Question about Vizio GV42L 42 in. LCD Television

Vizio picture polarizes

My Vizio 42" LCD is doing a weird thing where the darks drop out and turn into polarized red areas, like a photoshop filter. It happens a few minutes after I turn it on, and sometimes it stops on its own, sometimes not. It's not the cable box because it does it when playing DVD's as well. It seems serious, I hope I don't have to buy a new TV. Changing the contrast doesn't work by the way.

    Thanks a lot! That part isn't expensive but there's no way I'm going to try this myself. I'm going to start by unplugging it. Very possible there are power surges here. I'm in New Mexico.

It sounds like it has bad T-CON board due to poor 12vdc feeding it or failed parts on the board.

It sounds like the polarizer filters are starting to ware due to heat build up, if you remove the lid and the main booard, there is a white plastic mesh cover over the lcd panels, you can remove this and adjust the polarizers for the red, green and blue lcds to adjust the black level, there are 3 hex bolts holding a plastic frames which in turn hold the pre polarizer filters, buy slightly loosening the bolt you can slide the plastic frames left or right to adjust the levels, buy you should mark the position before you start. this may not solve the problem but may help to improve it, unfortunately these projectors require special software to make electrical adjustments which is hard to get hold of.

I,ve got a red spot in the screen i replaced the bulp but stil have the problem


it is most likely a burned polarizing filter. There is a polarizing filter on the blue light channel and another on the red channel. When black, or other dark colours are displayed, the red polarizing filter is supposed to block ALL of the red light being projecter. If the filter is burned, some light slips through and creates a red tinge on the projected image. If the red tinge only appears on dark images, but is absent when the images is completely white, a damaged filter is likely the problem.

Seems its hard to buy them. Best bet is probably buying a broken projector from ebay and stealing the filters out of it.

Yellow tint


Hello. Here's the visual key to remember about projectors--LCD panels show their colors like this: RED lcd panel displays cyan onscreen(baby blue); GREEN lcd displays purple; BLUE lcd displays yellow. ( You now know where the displayed dust is!) The problem is most likely a burned blue lcd or polarizer filter in front of the blue lcd panel. This occurs when the dust filter isn't cleaned regularly or properly and heat builds up--yes, enough to "cook" the lcd panel or actually cause a burn to develop on the polarizer. The polarizer is just like a lens in a pair of good sunglasses. It is a small, extremely thin, pane of glass with polarizer material glued onto one side. When burned, it causes a "shadow" effect--that enhances the display of that particular color--in this case, yellow.--Hope I was of assistance!---Rick

Color fades when wathcing TV from greens to reds and also get dark.


Typical problems with lcds.. When they get hot, the color tends to shift. The reason your seeing the problem on the red and green is because of a lack of blue.. Makes sence if you think about it as blue is the hottest wave of light, so the blue panal is getting too hot or possibly the polarizing filter on the tv..

Lamps can cause this somtimes as they tend to shift twords the higher waves at the end of there life.. So if you have another lamp, try it out.

Another possible cause is the driver board for the lcds.. If there is a chip that has a small short, it will overheat as well and cause it not to function properly. I see this all the time on lcd projectors. 1 of 3 things.

Blueish tint on picture


no... lcp panels will look different when going bad ! this is the polarization filter, most of the time the one BEFORE the lcd panel (blue in this case). these should be cheap but are not easy to get...so you might pay quite a lot. you can also buy polarization filter sheets and cut them to size. keep in mind to check for the right orientation !
