Hey there guys, it's been a while since I've picked up another tv project, so It's time to consult the experts yet again.
By the way, this forum has been a huge help to me in the past year. I really appreciate all the great advice & knowhow everyone has shared. Y'all rock!
Today, I found a Sony Brava KDL 40S4100 (2008) on craigslist. The guy took great care of the tv, almost perfect cosmetic condition with the stickers still on. Original remote.
The problem:
According to the owner, the unit started to get slower and slower at turning on. The owner would unplug it, replug it, and turn it on. This worked for a while until it finally petered out.
(To me, this sounded like something I might be able to fix. Power supply... Hopefully just some bad caps, so I went and got it.)
It has no power at all. I plugged it in, pressed the power button manually. No clicking, no blinking, no sound, no standby.
Opened the tv. No sign of any blown caps here, though I haven't taken the cover off of the A board yet. The fuse near the power supply is fine, reading '1'. Is anyone familiar with this model & maybe a common culprit for this particular problem?
I checked the forum threads for the model in question. Everyone who posted with problems, had standby power to the unit. Nothing similar.
I am by no means a tech or a pro, but I love taking things apart and figuring them out. I've fixed maybe 10 tvs. Trying to work smart here & get some good advice first. And again...
