Question about Philips 20PT643R 20" TV

1 Answer

Our Tv will turn on by itself, at full volume and I can't change the channel. The remote doesn't work at all, the only way to shut it off at all is to unplug it from the wall. It's only about 4 years old can it be repaired?

If someone has ever sprayed glass cleaner or the like on the screen , it's possible that liquid got down into the control button board.
It's fixable but it may be cheaper to buy another new.

"snow" screen, full volume, remotes don"t work

good day
due to the long time the buttons were not used, they tend to get stuck and this causes channels eighter to stay in one station or continou scanning. it could be resolved by spraying WD40 on the buttons and press it many times then dry it before operating the unit.
