SOURCE: TV is dead

Could be many things, possibly a vertical IC failure, or bad soldered joints, or problems with the power supply. Considering your questions, if theres a problem with the tube, you don't want to change it, it won't be worth the expense, and since you're asking, then you probably shouldn't try anything with it. VERY dangerous, more or less like a microwave. TVs store very high voltages even when unplugged. What you could try is to unplug the TV over night, maybe the TV needs a bit of a discharge. also try another power outlet. other then that, you better take it to repair shop. Good luck

The set is still sensin a problem thats why it shuts off, in this units the problem is in the vcr section,check the cassette assambly sometimes is jammed and it will not load or one side of the cassette tray is pushed in too far or misaligned.It will continuo to shutdown until the problem is corrected.Be careful when working on it.

SOURCE: rca (tomson)t25062 keeps shutting off

First thing to check would be L401. Its a small coil from the secondary side of the horizontal driver transformer to the Base of the horizontal output transistor. Not a solder problem, You must take it out and scrap off the leads to remove the excess enamel paint the reinsert and resolder. Also check connections on the driver transformer too(horizontal). Next check for bad solder connections on the flyback transformer too. Good Luck PS please dont forget to rate this thread.

Tv wont turn on, geen light flickjers but goes back to red and does ot turn on, i unplugged tv while it was on by accident.


The main board and or power supply is seeing a problem is shutting down the TV.
The cause for your issue could be the power supply, main board, and or the drive board(s) that drive the plasma screen. Sorry, but to trouble shoot that issue would require some TV tools and knowledge of electronics.
Perhaps the following can help you with a warranty repair.
1. If your TV was purchased from January 1 2008 to today---The TV does have a 1 year warranty on parts/ labor and a 2 year warranty on just the plasma screen.
2. If your TV was purchased before January 1 2008---The TV does have a 2 year warranty on parts/ labor and a 2 year warranty on just the plasma screen.
I hope this information has helped you.
Good Luck.

Power will not stay on


With a problem like this, I would use the warranty for the TV.
It's possible a circuit board failure has occurred and the TV is automatically turning itself off to protect it from further damage. Is normally called " Protection Mode " for most TVs.

Being that it's 2 months old, it should be under warranty regardless. I would recommend contacting the store of where it was purchased and have them help you with the warranty issue.

TV keeps shutting off automatically


Since your plasma is less then a year old, I would suggest to contact the manufacturers to get it fix under warranty. If the plasma keeps shutting off by itself, that is not normal and should be repair.

LG 50PC5D-UL Plasma TV.... While playing XBox360 the screen just shrunk to the top 3" as though some one was holding a towel over the bottom portion of the screen. I have unplugged all inputs and the unit. I have let it cool down. Still it remains in this condition. I can't see the menu because it's in the portion of the screen that is "blacked out". What do I do?

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
