samsung hcl4715w shuts off, help

When I turn the set on, red light blinks a couple times, and the set shuts off immediately. I replaced the AA9501846D board with AA95-01846D from partstore.com, and the set turned on and worked perfectly.. for 30 minutes, then shut off. Now, can turn it on when it's cold and it works for a brief period before it shuts off.

I'm not a tech, but have stumbled on this website looking for alternatives to the inevitably expensive service call. The only shop in town only does house calls and has quoted me $300 minimum for what he thinks would be my problem.

Replacing Sony Convergence ICs

I have a Sony KP-51WS510 rear projection TV with convergence problems.  I am replacing the convergence ICs and have gotten hung-up pulling the board.  It seems that it is somehow secured in the area of the transformer (flyback).  It's not lifting or sliding, I've pulled all of the board screws (I think) and am hesitant to "muscle" it.  Any ideas on what I'm missing???

Mits 46805 - replaced IC's - picture now too Dim.

Having a problem with a Mitsubishi wt-46805 - I'm trying to fix my
father's TV that developed convergence issues. I replaced the
STK392-040 IC's with new ones from Acme and it fixed the convergence
issue, however now the picture is really dim.

The picture seems to be dimmer on the right side of the screen, but
it's like looking at a 20 year old tube set, just unwatchable. If I
activate the "iris" feature the picture goes completely black.

AKAI PTH5498 "Signal : *******" Notification

I've experienced the "convergence" issue as well, but hopefully that is behind me, along with the $600 repair bill.  The problem now is an annoyance....When the signal changes from "MONO" to "STEREO" to whatever, I get this very annoying notice on the screen that say "SIGNAL: MONO", "SIGNAL:STEREO", etc. Some channels change signals very frequently, especially ESPN. Sure would like to get rid of the notice. Anybody with a solution (other than "A big hammer"........Thanks

Panasonic 52lcx66

My Panasonic 52" rear projection tv will not turn on when I came home from work and it might have been from a blackout. The TV does not turn on at all no light red or green. I believe its just a fuse. I opened up the back of my rear projection tv to locate these fuses. I found 2 on the circut board of what seems to be the right shape and size but....the clear glass that the fuse usually is s covered in white. Now also the 1 fuse near the pwer cord attached to the circut board has a clear plastic tape around it making it tough for removal.
