Westinghouse power supply

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.?

SOURCE: Blank screen when tv has been on for 10-20 minutes

Hi jilanfa00, 
I am happy to help, we need to check the backlight inverter.

  1. Turn tv on and get to a point that you have audio.
  2. Take a flashlight and shine it on the screen.
  3. Look very closely at the screen for a very dark video image.
If you see an image you have a bad inverter, you should be able to replace it yourself. I can walk you through in chat. Let me know your findings. Lone99star

SOURCE: westinghouse model tx-47f430s lcd tv wil not turn on

This is known as SLEEP MODE problem.

Simple solutions:
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 westytech@westinghousedigital.com. Please rate this comment if it was useful.

Why is it that my westinghouse 32 in LEDTV model#LD-3265 just went blank on me no sound no picture but powered up properly


Do the menus work or input labels appear when you change sources?
Have you tried unplugging the power with the tv turned on, waiting a few minutes, then plugging it back in and turning it on?

Westinghouse LD-4655VX Power on fine, nice picture, but around 5 minutes turn off self it,


If the set is still under warranty, the power supply board is going bad. If not you can replace it yourself. It's not that big of a job. You can find the parts you need at www.shopjimmy.com

Need to find out where power cord for Westinghouse ld-3255vx goes


Hello
You have to use an AC adapter to this set, which will be already been supplied with this set, when you bought it. Connect the adapters' output to the "DC IN" connetion socet at the back of the TV.

It can be the backlight inverter board is going out or the power supply that supplys the power to the inverter board is going out if what you mean by 'BLANK' no light on the screen. Look for bad capacitors in the power supply first it is easier to get to than the inverter board.
