Hello there are a few things that could be bad with your TV. First the t-con board might be bad. That would be my first guess. The signal board or the screen can also be bad on your tv.

you can get parts for this tv at www.interliquidparts.com

Need the operation manuel for my 22inch Gateway monitor can't change operating language


I have a smaller sized Gateway monitor than yours, but I'm sure the monitor buttons (on the front) perform the same functions on all sizes.

You should have eight control buttons on the front of the bezel (as listed from left to right): source, menu, down arrow, up arrow, left arrow, right arrow, auto/set, and on/off buttons.

Press the menu button, the first dialog screen that appears (at least on mine) is the brightness/contrast function. The screen will show the function to be changed, and a very small picture of what screen you have in view.

Once the first function is listed on the screen, press the down arrow to access the other screens (color, tracking and set-up), each having their own little picture indicating what screen you are looking at.

Brightness/contrast - picture of half light, half dark circle
color - RGB picture
tracking - two squares on top on one another slightly off center
set-up- hand pointing left

You want the set-up screen which shows a picture (I think) of a little hand pointing to the left. Once you are in the set-up screen, press the auto/set button and the first line will be highlighted (usually it is the language choice).

Once highlighted, press the right arrow button until your language name appears (i.e., English, Duetsch, Francais, Espanol Italiano, -there is no choice on mine for Japanese, etc.).

Press the menu button again and that should do it.

Screen shows blue patches on white also red lines on dark colour


Replace the video board, if you can find one. Letting it cool down will not help any.

LCD Philips 26pf8946 after about 45mins right hand 1/3rd picture not viewable


Hi Darnez,
It sound like to me that one of the boards that power the bad side of the screen is getting hot and quitting. The boards are not too expensive to replace but getting them is generally the big problem. ( At least for our company). The set would be worth tkaing to a local shop and have it looked at, but replacement costs are going down every day it seems.
Good Luck
I hope in some way this has helped

Left side of television just started having a shadowing problem?


I have the same problem and was told by a technician that I need to replace the light engine. Probably around $ 700.00.

Pictures are dark, even when flash is being used


Press the FN button under the toggle on right side of LCD screen. You will see white balance on left. Toggle down to the "flash" symbol".  Should work a treat now. If not using flash go to FN again and raise ISO.(Don"t forget to go to Auto white balance again!!)
