Westinghouse LTV-32w1 32 in. HDTV-Ready

I have sound but no picture.  The signal is on TV and it still doesn't work!  It worked fine before and suddenly went blank.  I need help right away.  Thank you....tattlerwest@aol.com My 2 year old LTV-32w1 worked perfectly until today. I turned it off during dinner and when I turned it back on 30 min later the screen was completely dark and blank. Sound is perfect and it seems to switch channels based on the audio.

1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key.

Try these first and let me know how it goes..

    If the troubleshooting steps above did not work, you may have to get the power board replaced. (that would be the easier option than having to replace individual components on the board.

    Most likely there is a bust capacitor/s on the board that need replacement. It could also be a problem with the convergence IC modules.

    As you can see, there are many things that could cause this issue, and its difficult to say exactly whats wrong based on my long-distance-judgment. I would recommend getting this inspected by a qualified TV repairman for an on the spot check and diagnosis...

Hello, you are getting some signs that your inverter boards on this unit are going to go out.

Its probably a broken backlight inverter, it costs about $130 for a new 1, and thats if you install it yourself, which shouldn't be too hard You can probably find instructions online about how to do that (P.S. Check before buying and trying to install yourself.)

Westinghouse ltv 32w4 hdc 32.02 in. hdtv lcd tv / dvd combo


My 42" Westinghouse HDMI inputs just stopped working. I thought it was the TW Explorer 4250HDC issue so I got a new one from TW. Still said no signal from HDMI. So, I shut the TV down and pulled the power cord out of the back. I waited a few seconds and reconnected the pwr cord. The TV "re-booted" so to say and now the HDMI inputs work. I think TVTEK has the right idea that it is firmware/software related. In the mean time, you might want to give that a try.
