Before installing replacement parts???

I can assume that the t-con board or the video board had terminal connectors or ribbon connectors. What is often overlooked is a misaligned connector or worse, a broken or bent pin. Try examining these connection points. You may have to use a magnifying glass. A defective screen usually goes black or produces broken images and/or color points.
I hope this helps.

Here is a great link for the manual:

Try page 21 through 25. There is no "factory restore" function, but you can adjust the hue and colors.

Hi, You may need a digital tuner to watch regular TV shows. (set top box) Your TV tuner may need also to be adjusted or repaired. Have a TV tech have a look at it. Good luck.

You may have turned the tv's speakers off. check your menu to see if thats the case.

Hi Dwayne,

The Proton has an NTSC analog tuner and also an ATSC digital tuner. Have you tried switching or changing the SOURCE inputs?
You may also have to use the scan button to have the tuner "find" the channels for you once you determine that you have selected the correct source for the antenna.
See page 9 of the manual.

Hello, I have one of these tvs and it works great. My problem is that my screen is cracked and cannot find a replacement. Do you want to do a swap, either for your screen or you can purchase my working tv, and replace with your screen? Just a thought. LRoller
