32LG3000 LCD TV shows no picture when resuming from standby

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

After the screen goes black, do you still have sound or you have none but a blank screen? If you have no picture and sound does the power LED in front of the tv indicate that the set is on, or does it go into standby? Please provide this info so that I can help you with your problem.

Sai.

Sorry about that. When the tv goes bad like not turning on, the green light will blink, and goes right back to red standby light while the dtv letters will briefly show on the lower right of the tv screen, then go back to blank screen. The tv will need to be taken to an authorized service center for repair. Common causes are a bad inverter/power supply, power control board, or circuit board.

I think TV on for minute or so, goes to standby and again power up, show picture for minute and again standby.
If above are symptoms then its time to replace lamp in TV.

Let me know if symptoms are different.

hi it sounds like when tunned in tv it was tunned in shop mode.
do a factory reset and choose home when installing

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

TV seem to be ok on standby but when a chanel button is operated the standby activates but the screen remains blank an no sound
