Westinghouse LTV-32w6 power light on, no video, no sound

Following an electrical storm, my out-of-warranty LTV-32w6 is no longer functional. After disconnecting and reconnecting power, I can press the power button and light the standard blue power LED on the front panel. However, there is no video and no sound. Pressing the power button again has no effect -- the power LED stays lit. I've used a multimeter to determine that the 5V line is active but all of the 12V and 24V lines are dead. There are no obviously damaged components on either the power supply or main board. I'm willing to buy a new power supply unit but replacing the main board will most likely be too costly. Does this sound like a power supply issue? Or could it be that the main board is not relaying the proper signal to fully activate the power supply?

    Thanks for the quick reply. I have observed the same symptoms and readings with the inverter completely removed -- nothing on the 12V and 24V lines, while 5V activates when powered on. I'm still relatively confident the power supply is at fault. Any other thoughts before I make my purchase?

    Exact same thing happening to me. I looked up other problems, which were similar, but not exact...which led me to take apart the TV and check for loose connections inside the unit. I now have a disassembled TV in my living room with no clear solution...
    If someone figures out exactly what is needed for this problem, I would love to know.

    belated followup: i ended up replacing the power supply unit -- i found one for just under 120$ -- and it's been working beautifully since then (nearly 8 months now)

    the supply i bought was not identical to the original part, though i don't recall exactly what model tv it came from. i took a gamble on my purchase after comparing the connectors in close-up photos in their ebay listing to the defective part i had. you may have similar luck following this same route.

    I've checked out before. They don't have a power unit for the 32w6. They do have one for the 37w6, though. Is that the one you bought, or is there something else I should be looking for? I'd assume it's the same unit, but I'd hate to get that one and it produce too much power and damage it even worse.
    Thanks for all your help!

    Belated, yet appreciated. My Westinghouse is still sitting in the back
    of my closet. Could you tell me where you ultimately purchased the
    power supply unit, and which model # it was?

One thing is to make sure the inverter board is unplugged when testing the voltages. A shorted inverter will shut down the power supply if the fuse dosen't blow first. There are fuses that don't look like fuses so they can be missed. The next thing would be to look for a connector from the main to power supply and see if there is a pin labeled power on or p.on or similar. The main board should turn this line high(5V) when you push the power button. If not you probably have a bad main board. Unless you can find good used boards they are both expensive. Around $200 for PS and $300 for main.

Why doesn't it stay on channel?

Gustav, Try factory reset, to get to the Setup Wizard. With the TV on press the menu button on your remote. While the menu is displayed press the 0 button four times. This should bring up a new menu with factory reset as an option.
Check the attached links,

I simply disconnected my ltv 32w6 and now I have no volume. can you assist me ?

Do you mean no sound or no volume bar on the screen when you push the volume at the remote or at the TV?
If it has no sound, then:
Let verify first to narrow down to where the problem can be. First, make sure the MUTE function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

My Westinghouse LTV-32w6 HD has sound but no picture

You may have problem with the T-C0N board, worst case will be the main logic board, try cooling the T-CON board with electronics freeze spray to see if the problem will go away, you can get it from Radio Shack.
If you are going to DIY and have proper tools and know safety precaution then please read on:

I bought a 32 LCD Westinghouse TV 12 months ago. It stopped working so I brought it to a TV repair shop. They determined that the main board went out. The TV's power supply is working but there is no screen or sound, nothing. The TV repair shop had to call Westinghouse to inquire about a replacement part. Funny, Westinghouse doesn’t make replacement parts for this TV. Westinghouse said we need to ship it back to them and they will send us a new TV. Okay that sounds good but they wont pay the $100 plus shipping costs for us to ship the broken TV back to them. Also, they make you send them the TV before they send you the replacement TV. That can take days. If the customer's TV went out because of the company’s faulty product, the customer shouldn't have to dic around with this shipping issue – Waa, Waa! The TV was nice but for it to conk out in one-year shows what shi++y merchandise Westinghouse is selling their consumers. “Buyer Beware”
