Question about Westinghouse LTV-40w1 HDC 40.02 in. LCD HDTV

3 Answers

Abnormal Screen Color/Resolution

I bought a Westinghouse LTV-40w1 HDC 40.02 in. HDTV LCD TV/DVD Combo about 1.5 years ago from Best Buy. Everything worked fine until it was disconnected it and gently moved the TV to another room while we painted. When we re-installed and turned on the screen image contains abnormal colors. A lot of blues and pinks. Have tried adjusting all differnt combinations of screen settings, (brightness, contrast, etc.) and nothing works. The abnormal screen colors happen with both cable and DVD. Is this economically repairable? Thanks!

    Is there another potential solution? Speakers are not hooked up. I shut down for 45 minuts and turned back on but problem persists.

    Do you know potential faults? THanks

  • random99 May 23, 2008

    Speakers were not plugged in but I moved them away from TV. I turned off TV for about 45 minutes and turned it back on and problem persists. Could cable box or cable phone receiveer stored nearby also contribute to problem? Thanks

It seems more a problem due to an external electromagnetic field. You can try using a degaussing wand, or try to realign the position of the TV.
Try removing any sources of electromagnetic radiation away from the TV. These include magnets (Speakers have magnets) and radios, etc.

You can even try a hard reset..unplug from wall and cables, wait about 15 minutes and replug.

Hope that helps! Should you have any further questions, please post them here.

    Well, if the degaussing did not work, it could be one of the smaller components on the main board that could be faulty. It is difficult to say exactly which, without performing any tests . However, the defective capacitors should be easy enough to identify. Their caps (tops) will be swollen and bulging. Here is a sample pic:


    The resistors are a bit more difficult and cannot be identified without an ohmeter.

    In any case, should the degaussing not work, I recommend getting a qualified technician to take a look. If the fault is just with the capacitors/resistors, then repair should easily be under $100. However, if one of the larger components are faulty (which I doubt), then the cost can go up likewise.

    Please check with Best Buy first, if your TV is still under warranty, cause this would definitely be covered by warranty.

    Hope that helps!

It depends on the fault, it seems it will be good if you go for repair

It has a magnetic feild nearby

    If you turn it off at the wall and leave for about 20 mins, then turn it onn again, it should DeGauss and reset the magnetic feild about the picture tube. If you have HiFi stereo speaker nearby, they too will create the colour impurities that you mention. Remeber, it is an external magnetic feild that causes the problem, so be aware of where they may be in relation to your television.

Hi Patty Jo,

I would suggest calling 1-888-Best Buy™ or 1-866-287-5555 for Westinghouse Support. Typically televisions become an in-home serviceable item near the 25-40 inch range.

Thank you,
Jason,
