I have a Westinghouse LTV 32w3 HD LCD TV (LTV32w3HD)and it does not come on. I know it is getting power as when i unplug from the wall i can hear a noise.

If everything but the HDMI is working, its a possibility that the source has a compatibility issue or your TV needs a software/firmware update needed

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.

my tv says no signal, and everything is just blank. my tv is a samsung 27, and it doesn't say anything. we tried everything like rebooth, and all that stuff. but it doesn't work plzzzz help!!!

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

The "lvds" cable which is connected to the lcd controller board is taped to the backlight housing and is transmitting interference to the controller board. Remove the tape and pull the cable away from the backlight housing slightly. You will have to remove the mainboard to do this since it is underneath it. Do not touch the power supply or power supply connectors (dangerous high voltage).

I had the same problem these LCD TV's are designed poorly and have very little ventilation my warranty was up so i took it apart and installed cooling fan have no problems what so ever now.
