The circuit is pretty simple - back when resisters where 1cm long and capacitors where big and fat. (ie: 1979 sort of stuff) The problem The problem i'm having is - instead of a single horizontal scan line, i get multiple horizontal scan lines. (see attached image). If i'd have to guess it be something like 10 of them. That's 10 scan lines all bunched together. Its as if the focus is out - way out. Hard to explain but you can see it working. I've checked the vertical amp, which control Y defection plates and works. The horizontal amp looks like its working - i mean there as 7400 TTL nand gate that does some tricky switching, but roughly measuring the voltage and waveforms seems to be there. The horizontal amp circuit also does the blanking (as well as the alt (dual channel display) and add (adding both channels to the vertical amp) My question is would the FBT (or circuity) be the cause. The unfortunate part is none of my test equipment is rated above 750ac - so im not able to place any test probes in that area. I was thinking of placing a large 1M 10W resister in the circuit and measuring that - but don't know if that works or if it will load the diode pump circuity too much. - Any ideas? Has any one seen something similar. Could the blanking circuity be the cause. http://genesisrealtycorp.com/images/canon-uc8000-manual.pdf

Looking at the capacitors (visually) nothing looks strange, no bulges or anything like that. The diodes and the bipolar transistors all conduct. I'd hate to retire my trusty CRO. Thanks for any help in advance. joe First suspicion would be the PSU reservoir capacitors on the low voltage supplies, it doesn't sound like a high voltage problem. Try changing C264, C265 and C266 first. It is worth spending a little money on fixing it. Brian. My CRO doesn't have C233 to C299 - however the point not lost. However, i just noticed (10minutes ago) that when i connected my multi-meter to one of the terminals of the focus POT, the trace returned to a single trace if not briefly (????). The focus is made of a series circuit starting with -1450V through to 1M5, 2M5 POT (focus) and then a pair of 3M9 resisters to ground. There's also a bypass capacitor (0.01uf) between the pot and ground. I can't check the -1450V directly as none of equipment is rated that high:-( However, i disconnected the bypass cap (0.01uf) hoping to see any changes - none. Do you still think its low power. Either way i'm checking all the power. (and the bypass caps) The -1450V is coming from the FBT via a pair of RC circuit and diode. (perhaps i should scan the circuit diagram) NB: 50Hz (Australia) PS: happy to spend the money - might have to look for a higher rated multi-meter. Either way hate to see this CRO not operational. Its survived too long to give up now. Looking at the one I have here I can see its for a similar but not identical model so my apologies for the false diagnosis. It COULD be a simple focussing fault but the fact that you can still adjust it and focus part of the image makes me think that isn't the problem. You should be able to confirm the resistors are OK by measuring them with a Ohmmeter, although rated for high voltage they will still measure as normal resistors. If they are OK at testmeter voltages they should be OK at 1450V.

I would concentrate on the power supply to the sweep oscillator and deflection amplifiers, as there is no apparent pattern to the 'fuzz' I'm guessing it isn't trying to display something but is more likely to be randomly scanning. If you can scan the schematic I might be able to give some pointers to likely culprits. I only have slow internet so if you can make it JPG or better still a PDF it would be appreciated, big files are difficult for me to download. Brian. I agree that a focus problem seems likely at first sight. Does the brightness control still work? The photo isnt a good one, it does look like a halo, however when you wind up full brightness then it becomes clearer to see the multiple scan lines - only my iphone can't seem to see that detail. So yes brightness still works and works well. Also it seems that a BWD 525 service manual are rare - so i've scanned my in and have attached it. It contains all the circuit diagrams, descriptions etc. On page 55 has the circuit diagram for the power supply, while on page 36 shows me how to and where to test them. All the power supplies (except for the -1450V) i can test and have tested. I registered a 45mVpp ripple and the specs are saying There must be an unwanted y deflection signal, the trace should reveal (thin scan lines?) if focus is O.K. or not. Faulty power supply filtering (e.g. capacitors dryed out) becomes more likely. First guess would now be C1 or C2 (or both) are dead. I would think the problem is on the 113V and 100V lines from the power supply. It feeds both deflection amplifiers so any ripple on them will show as deviations in the trace. Note that the reference voltage for the stabilizer comes from the -15V supply through R6 so that could also be suspect. It tells you how much ripple is acceptable but of course you need another oscilloscope to check it! Brian. It eventually gets to the positive side of D5 and i get a 25mVpp ripple coming through.

I don't have any caps rated that high so thats shopping tomorrow.NB: the size of C1 and C2 are as big as salt shaker. They degrade over time even if unused but with constant use will only have a few years before losing efficiency. Over 35 years or so, I would be suprised if they worked well at all. One of the first things done to recondition older equipment is replace ALL the electrolytic capacitors with new ones. Brian. A brand new can type today will probably have a life expectancy of just 2 years at max operating temperature and a declining graph as the temp lowers but still - Personally I'd change them all before spending too much time on other things given the age of the scope. Oh - Yes I see brian said that - course he would sorry! This is a common problem with scopes when they age. The pots become intermittent or develop cracks in their tracks and go open circuit. One of the resistors in this assembly can also go open circuit or intermittent. Make sure all resistance values measure ok. You should measure about 450V across the focus pot. Be careful with measurements around here as you could damage your meter if not rated for these voltages. You may need to get an HV probe to use with your DVM. Although this initially looks like a focus problem, the focus and brightness controls still work and some kind of image within the halo can still be made sharp. That's why I suggested it was interference in the deflection stages rather than a CRT voltage problem. It's one of those jobs I could probably fix in 5 minutes if it was on my bench and not almost exactly half a planet away ! Brian. Even if there not entirely the fault it can't hurt. I've check RV53 which is the focus control and confirmed its resistance - first thing i did. Its pin 8 that i placed my multimeter, that resulted in a return to a single trace. RV52 and pin 11 i have yet to check. My multimeter input resistance is measure at 10M, placing the probe must of sank some of the signal. {-Variable.fc_1_url-

PS: forgot how much fun it is messing with discrete components. Measure between all terminals and make sure it is not intermittent over its travel. I suspect a break in the top half of the track to terminal or connection to the resistor assembly. One more thing you could try as a test is to take a 10M resistor and solder it between pin 8 node and GND. If that restores the trace, you know you have a problem with the pot or resistive divider. Replacing R77 fixed it. So basically i must of stuffed up and couldn't measure resisters if my life depended on it. Before i made this post i measure the series resister and also the POT - at least i thought i did - now i'm not so sure any more. Really embarasing. Now to work out why the scan line doesn't use the entire screen. Many Thanks Joe By continuing to use this site, you are consenting to our use of cookies.

I would pull it and there was no resistance. The second one had the cord get all tangled inside. If they could make the starting more reliable, it would be a good product all the time. The corded electric starter is a must. These things need to be warmed up. Not 30 seconds or 60 seconds for that matter. Let them run at starting speed for 5 or 7 minutes while your cleaning and putting the mower away. Unlike 2 stroke engines that get their power from RPM's, 4 stroke engines get their power from torque. This need not be run in WOT, a moderate RPM and the torque generated will power through most things. They do not recommend using line larger than.095. I have chain link fencing, and it eats trimmer line. I run mine on.105 line and I get better line life than.095. Away from the fence the.105 line is indestructible and devours everything even saplings. To reload line from bulk, stretch line from your nose to arms length, 6 times and cut it off. It's that easy. This tool has never failed to do what ever job I've done from weed-whacking a 400 foot long ditch to tilling the ground for a new garden and flower bed. I can sum it all up in one word. Impressive!! It was defective out of the box. Something was rattling internally and there was no resistance on the pull cord. It would not start using the pull cord or the electric starter. I returned it to Lowes for a replacement. The replacement worked fine for that usage. When I tried to use it again several days later, it wouldn't start manually or electrically and had the same symptoms as the first unit I purchased. Lowes took it back and refunded my money. I wasn't impressed with the weight of the trimmer, it's length, and the throttle switch. It's quite heavy, too long for my reach, and the throttle switch is quite bulky and requires large hands to maintain grip while in use. I bought the trimmer from Lowe's July 2012, and the trimmer motor runs great. When the Cutting Head Assembly broke I ordered a new one and tried to remove the original Head. My internet search for a procedure resulted in finding out that the version of the TB525EC that I have was built without a slot in the curved shaft, which would normally allow easy removal of the Cutting Head Assembly. The version TB525EC I bought has a plastic collar on the shaft just above the Head, but there is not a slot where a screwdriver or pin can be placed to hold the shaft while Head is removed. I know others have the same issue, as I found out from Internet postings. QUESTION: Is the a procedure to remove the Cutting Head Assembly? I previously purchase 2-stroke trimmers, but got tired of the undependability of starting them. Thanks Troybilt for making the best trimmer available. When you have to do 8 steps just to start it I should of know better. Then when I get it going and move the lever to the final position it stops. Then what. I am so disappointed that I gave up and used my old one. Jump start is great but, it starts early as pull start. I did add replacement solid blades.
