Question about Samsung LN-T4665F 46 in. LCD Television

Open Question

Samsung LN-T4665 tv Screen blinks between regular brightness and dark picture quality several times and then remains with darker colors. About 2 weeks ago my Samsung LN-T4665F lcd tv picture started to display a very dark picture quality. I turned the brightness and backlight both to maximum which made it better but was still dark. The next morning after being off overnight I turned it on and the picture quality was back to regular brightness. After about 1 hour the picture blinked several times between the regular brightness picture and the dark picture then stopped and remained with the dark picture quality. Now every morning the picture is alright for about 15 minutes then blinks several times and finally changes to the dark picture quality. I noticed that if I turn off the source in Dynamic mode the screen is a dark grey on the left part of the screen while the area to the right that is near white.

Hi. You can try to go into service mode and reset the LCDTV to Factory Default. This will clear out all buffer over run's and any software related issues. It may fix the problem or it may not. If this doesnt fix the problem than you need to have a qualified Technician to look at it. The problem is in the AV circuit board, a technician who is qualified to repair electronics at circuit board level should be able to repair this problem rather quickly and inexpensively. Most technicians who do not have the expertise in repairing cicuit boards to component level would rather replace the whole AV board than repair it and this will be rather expensive.So talk to the repair shop before you drop the TV off.

Be very careful when accessing service mode. I suggest to write down all information in all areas before proceeding to a factory reset. If you do not record all values correclty you run the chance of not being able to use the TV again. To go into Factory Service mode, use the original remote and in this sequence push POWER OFF-MUTE-1-8-2-Power ON, the set will turn on and enter service mode, if you hit all previous keys correctly. If it doesnt try again. When you are done hit POWER OFF and this will exit service mode and save the data.
