Ok, up front...based on all the reading I've done so far, I should just pitch this in the trash and save myself the headache. That said, I've tried to research as much as possible and here is where I'm at:
- U5000 chassis set to medium res
- no neck glow, no picture
- I do have a high pitched buzzing when the chassis is powered up
- the buzzing seems to be in the HV area
- while checking voltages on the bottom of the board, the buzzing would stop when i touched some of the pads on the resistors that lead to legs on the U101
- I did the light bulb test and got no light at all
I've seen multiple suggestions that said start with U101 so I'll do that first. Before that, I wanted to ask a few questions.
- should I start pulling and testing all components in the HV area or are there some specific ones I can focus on?
- Is there a set of components I should just replace from the start and skip the testing?
- Is there a specific place or person where you can order non-standard items like U101 or do you just need to start tracking parts down at the various electronics sites. I've mainly dealt with flybacks and cap kits up to this point.
Thanks in advance for any help you can offer. This forum is awesome... and a treasure trove of information! You folks are great.
