This Westinghouse tv 1080pure will not turn on, all it shows is the orange light every time i plug it in. I've tried unplugging it and plugging it back in but it still dosent turn on

Try this....with the TV off put a hair dryer in the back lower fins of the TV and let it run on high for about 5 mins, shut the hair dryer off and see if the set comes on the way it should..If it does I'll tell you how to fix it, if it doesn't I've got some other ideas but want you to try this first

The main board is out.

Hi i would need more info. what is the model number. its not always the power board it can be a processor fault. and thats the main av board. the processor is what turns on all the parts to start up.

Check and replace the main power supply regulator board. http://electronicshelponline.blogspot.com/

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.

I had a similar problem with 2 other lcds. In one of them there were 3 capacitors that needed to be changed. In the other the main (biggest capactior) needed to be replaced. Someone may have already posted the solution for this tv with more details than I can provide.

I just fixed the same model and with your symptom. What it appears to be is the main module is locking up just after the Logo goes away. All you can do is unplug and try again and all you will get is the logo for 5 seconds and then black screen, no sound and led stays lit. Cannot turn off or on. The power supply is actually working fine, it's the main module that has died. This module is no longer available, the part number was W470PROLX68. What i did to restore operation on this unit was to insert 3 volts into the plug going to the master inverter board and then plugged the tv AC cord in. The set showed the logo and then it started working. I removed the 3 volts and it has worked every time since then.
Here is what you should try to do: First take two AA batteries and solder them in series and attach two short wires so you can use it as a power source. Now you have a 3 volts power supply. Next Remove the stand first before removing the back cover. Looking at the back of the unit you will see the power supply and the main circuit boards in the middle (under metal shields) and two boards on each side. These are partially covered with a metal shield, the one on the left side is the master inverter, the one on the right is the slave inv. They both have a plug and wires going to them from the power supply, but the one to the master will have two extra wires. I believe the colors are purple and blue, and they are separated with an empty hole (unused part of the plug). The wire on the end is where you will hook up the positive lead of your battery pack. The negative lead simply goes to the metal shield. With these hooked up plug the tv into the ac and give it a couple seconds and hopfully you will see the tv come on. If it does then disconnect the battery pack and try it without it. good luck.

I had the same problem...turned out it wasnt the TV at all. It was actually the wall socket. Seems I had to many things plugged into one wall supply. (i.e. xbox 360, wii, audio reciever, dvd player, vcr, etc...) after switching some other items to a different socket my TV works GREAT!! I hope your problem is this simple!
