    were you able to solve with this fix? Service man was here today and told me that parts were not avail.

    I replaced the 2 stk convergence modules part numbers STK392-040 and also replaced the vertical deflection output IC part number LA7845 and it did not fix the problem. It is doing the same thing. I do hear the sound amplifier clicking while trying to turn on.

    I lost picture, the power button continues to power on, the sound comes and goes for a second only when it tries to power itself on.

Hi.

Either the stk convergence modules or the vertical ic have failed.
replace the 3 parts and it should fire up again.

The TV turns on and off after a few seconds and repeats itself.


There could be quite a few things that would cause the set not to power up. I dont have the service manual, however you can get a copy of the service manual at the following link for your model. As thats the only proper way to be able to check for the proper voltages to determine whats wrong with the set.
Heres the link.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

TV turns itself off after a few seconds, no picture at all


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
