After a forum member recently posted his LCD TV failure, I figured I could do this write up, hope it helps.
(oztules, please chip in anything you may find omitted, wrong, or otherwise helpful as you desire)
Sorry images were an afterthought on this project, so not many to show what was done.
I picked this LCD TV up some time back, of course because it did not work.
The problem was the typical power supply capacitor problems that plague many LCD.
This particular supply was designed a bit less than great from the start.
These power supply are built to work over large voltage ranges, and with less than perfect power but these supplies are mean on capacitors given the bad ripple they feed these caps even with the best of power conditions.
This is the TV with the back off, in this set the top module is the power supply.
It should be easy to pick out as in most LCD sets its the one with the big caps, transformers, and likely the largest heat sinks
( FYI this is certainy not true in a plasma set)
In this set there where two caps at fault, it was very easy to pick out the problem as these had swelled and leaked
These where the two black caps near and right of the two yellow transformers. Pictured are the new caps already installed.
Sorry I do not have the images of the originals available at the time I typed this up.
After finding and installing some caps that had somewhat better specs for the circuit, replacing the fuse, and reassembling everything
I had a new ( to me) cheaply obtained television.
This seems a fair walk through for someone with average electronics ability , Im sure there are hundreds of such videos on youtube, maybe even for whatever model you may be working on..
