Question about Televison & Video
I have a Westinghouse TV Model LD-4650 and the screen went blank. I've tried all the remedies with the power adapter but no luck thus far. I've ordered a new replacement ac to dc adapter from ebay but won't get it til sometime next week. I'm hoping it will fix the problem. The model of the adapter is: ENG model:3A-903DN19. QUESTION: Is there anything in the meantime I can do? Like pushing a combination of buttons on the TV etc.?

This is known as SLEEP MODE problem.
1. Get a power surge protector / strip.
2. Plug your TV power cord to the power surge.
3.Then turn-on your TV using the remote control. Just in case it won't go all the way to normal state.
4. Turn-off the switch of your power surge like 5 times with an interval of 3-5 seconds.
5. Then repeat step 3 and 4.
6. These step is done to over-ride the sleep mode.

This sounds like the inverter board has gone out. The inverter board is in charge of turning on and off the back light. If this goes out the TV is still able to fully function meaning you will still get power indicator to turn on, but since the back light is off you cannot see anything on the screen. You will need to replace this part so your TV can be fully functional again. For more information on how to replace, obtaining the correct part #, and parts as well as price availability please send me a quick email to email@example.com.

One of two symptoms on this model (LTV-32W6HD) Blue light comes on but cannot shut off. No picture; OR No picture but sound is OK. 1: In both cases replace ALL the electrolytic capacitors onthe output side of the power supply. This should get the power switch to worknormally. 2: Replace the small tiny wee little tiny small 2.0A fuse onthe inverter board labeled F1. This is the small black fuse, not the slightly bigger whiteones labeled F2 and F3.Ta Da...all fixed.
