We have a westinghouse lcd 32w3 hd and when we hooked up a hdmi for the first time the screen went black and no picture or sound, how do we fix this?

If you have n input setting, change it to ant.

Likely have a bad cable box. Could cable have bad connection before box also.

Why pay GOLDENREPRICON when you can download it for free? It is a ripped off!

You need to replace the LCD controller board, there are two versions (V320B1-C, 35D003848) you need to open up the tv and remove the shield cover to get to the LCD controller board, this is a common problem with this model. Look here parts (make sure to get the part number of the LCD panel sticker to match wit the LCD controller): http://www.shopjimmy.com/catalogsearch/result/index/?q=LTV-32W3HD&stock=all

You cam see the one I fixed here: http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/

Notes: be real careful when you remove the back cover, the side switch assembly is attached to the back panel, so do not pull it off too far, or you will damage the switch assembly!

The LCD controller is bad, after about on for 30 minutes, see sample here: http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/
Notee: my pix show the board with the cover removed. You can run the TV with the back open and have s small fan blowing in the back to keep it cool.
You need new LCD controller (there are more than one version, you need to match with the LCD panel): http://www.shopjimmy.com/catalogsearch/result/index/?q=ltv-32w3hd&stock=all

The "Picture in Picture" function will only work with a "digital" source like hdmi or dvi input. It will not work with an s-video or vga input source.

Hi John.
Try unplugging the TV for about 30 minutes to an hour (reset TV) to see if this fixes your issue. If it does not, leave the TV unplugged all night and see if it will operate normally. Hope this helps.

hi possably is the fan in the back make shour it is working all the time that there is no dust bild up on it stops it from spining it may need a cleen ,or it is a transister heeting up and cooling down the transister is on its way out it will be a hard fix for a tech to fined thay will fined it but it will cost you a heep ,its best to whate till its gon completly .cheers peter

It is worth fixing but you have to replace the power supply. It is a fairly common problem with the Westinghouse units.

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.
