Samsung TV LN46B630N1F

Screen is black when you turn it on then white spots fade in and out on different parts of the screen. It almost looks like it is trying to calibrate the screen, but no picture ever comes on.

SOURCE: My SAMSUNG DLP HLT5675SX TV seems to develop

It is the chip that controls the millions of mirrors inside the tv. If they are black, they are stuck closed. If they are white, they are stuck open. I JUST had the same the same thing happen with mine. I bought it 3yr and 2 months ago and I had an extended warranty on it for 3 years. Well, needless to say, it was out of warranty and I was pissed. The store I bought it from suggested I call Samsung. Which, I did. They asked for the model number and told me that my model (hlt5675sx) was one of the ones that is covered becasue they had a problem with the chip. Within 2 weeks, my tv was fixed by a repairman who came to my house. It works perfectly, now and it didn't cost me a penny. Good luck.

I believe it is the digital projection chip that is beginning to fail. Causing white and black spots to appear. To repair this may cost more than a new tv. If you want to attempt it yourself check out the above link. Hope this helps

My tv has small white dots of lights in most of the screen can this be fixed.


Ensure your input device is not causing this, by changing the TV input to a different video device. Then, look for any loose contacts on the RC cable or input cable. If nothing works, better refer it to a qualified service technician.

Hp dv9000 switches on to show coloured lines on screen.


Hello

My first guess is that the screen circuitry has gone bad - although fixable. Use an external monitor to verify this. If the external monitor is fine then the screen circuitry is bad, if the external screen shows the same problem then the video chip or associated circuitry has gone bad. My company fixes these all the time.
