SOURCE: element elchs321----tv cuts off on

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors. That crackling sound is the capacitors burning out.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

When the power is off, I can see the red light on bottom left, but when I turn it on why do I get nothing, no picture, sound or anything?


The red light indicates power is getting to your TV and it is in "standby". When you turn your TV on, an open internal fuse or power supply failure may be preventing normal operation.

No sound, no picture


If by catscan sound you mean a high pitched whine? That usually indicates that the power section has had a part fail. The capacitors on the main board will cause this. You can take it to the shop but get an estimate first as the repair cost can be close to replacement as the prices keep falling. The repair parts are pretty cheap but the labour isn't.

DP23 LED not lit on deflection board no picture on tv


Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

No Picture, Power LED goes from Blue to Red


It sounds like the red LED is signifying a fault. Check your manual (or ring the manufacturer's support line) to find out what the red LED means. If it does in fact signify a fault, file a fault with the manufacturer and return it to them under warranty (if you still have it).
