Ive owned the LG plasma for several months now and I am having a problem with the set failing to respond to being turned off and on.Also the tv is failing to repond to any switch's leaving me with a the set turned on but no picture no sound and wont do anything. However unplugging and reinplugging seems to cure it, its becoming quite a regular problem!!! Engineer has been called out (COMET) but did nothing as it did not happen whilst he was here infact he never even took back of the set off.
Usually this problem is caused by poor solder connections on the main power supply board. The unit being a plasma tv has many supply voltages and sometimes has multiple power supply boards. By removing these boards and resoldering any suspect connections, the problem is usually resolved. Many companies will do anything to avoid repairing a unit that is working, even intermittantly. Call the responsible parties and demand that they service your unit properly, not brush you off. Scrivitron
I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem.
My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of
course) and found four bulged capacitors.
Many electronics companies were sold capacitors that failed in 2-5 years
instead of 10-20. The capacitors fail
prematurely due to a lack of preservatives. Unfortunately, they were installed in all
sorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional
2. Open your TV and find PSB. Check
for faulty caps. If you find some (bulged
or leaking) bad caps replace the entire board.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourself
it will save you hundreds.
I have a tip/tutorial
on this site that may also help. It
gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's
called: Fixing the Philips Turns/shuts off on its own problem.
Hope this helps and Good luck.
