Question about Olevia 237T 37 in. LCD TV

1 Answer

Periodically we will lose pic and sound for a few seconds or a few minutes. sometimes it comes back on its own, other times we have to turn tv off and back on to reboot. sometimes if we have to turn it off it will go into the flashing led mode and we have to turn main switch on back off and on to get tv to play again.

The ambient temperature might be high. Check whether the foolinf fans are working or not. If not, check out the reason for it. The TV must be placed at least 6cm away from wall, and should have sufficant ventilaation.
