Having problems with your Flat Panel Televisions ?

I bought my Samsung LN40B530 nearly two years ago from Best Buy. Last night while watching cartoons, a vertical white strip about 4 inches wide appeared on the right side of the screen. This morning, the whole screen is white, and that strip is in color, but discolored. The sound works, the menu buttons work, we just can't see anything on the screen. Is there anything we can do?



Answers :

It cam be the LCD panel, T-CON board, or main board. Very difficult to narrow down to exact baord without manual and proper tools. I would first find out if the switched 12vdc feeding theT-CON board is OK, also try reseating the ribbon cables on the T-CON board.

I have a 2003, KF60WE610 60inch TV. My TV started occasionally losing the picture. The TV will go from normal picture to color patterns yellow/orange, green/blue, black and white. Then I'll have a black screen. The sound is fine. The picture returns without doing anything. The lamp light does NOT blink. The lamp was replaced a year ago. The green power light is steady. What could be the issue?

We have a Mitsubishi WD-57733. The lamp went out and we had a TV Repairman put a new one in. Then less than a week later we had the white dots on the screen problem. Mitsubishi sent someone to replace the DMD chip. After having these to things done whenever the screen is white or light in color, we have noticed that there are 3 very large magnified fingerprints on the screen. Mitsubishi sent the tech out again and he said it was not anything he did. He did clean the lens but the fingerprints

I have an LG LCD TV...model #52LD550-UB.AUSMLFR. Was working fine last night, turned on this morning to a massive white screen. It still has sound, just on a white screen. I turned on the surround system and have picture on that using the AV1 component, but nothing when using the HDMI1 component.

No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip.
