Check all the voltages that comes to its back-light inverter, from the main power supply regulator board. Check for any loose connections with the connecting wires in between. Re-seat all of it once and check. Back-light shuts off; after some time by anyway, is the problem to your TV. If you wish to get some details; check the site linked here.

SOURCE: Samsung LCD TV, no picture only sound

My Samsung LNT4669F has two problems..the first is that it takes about 3 minutes to turn on. The red light at TV bases flickers on and off but the sound is there back and forth..Finally, the wite light at base turns on and the TV makes a noise as if it just got turned on and it stays on..why does it take so long?

Secondly, sometimes, the HD channels flicker so badly that I cannot even watch TV..so badly that sometimes the picture is blank..however, the regular channels are fine..Can you help?

SOURCE: samsung 27" lcd tv picture goes black, still have

0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!(*&^%

How do I repair our Samsung LCD Television? I would really appreciate an answer ASAP. Where will my answer appear for my review.


Don't know what service provider you have, free to air, satellite, cable or what? Try feeding the TV another signal and see what it does. Play recorder movie from DVD, or if you have a VCR around even try that. If it plays the DVD etc, with no issues, then TV is not the problem, most likely the cable box, satellite box etc, could be as simple as a bad cable connection at the house, a splitter or street box. Eliminate all the simple things first, then look at the TV.

My tv keeps losing the picture, i can still hear the sound but no picture after i turn it off for a few minutes it will come on again.


Overheated semiconductor circuit. Maybe due to moisture condensation. Use a fan to cool the back of the tv?

I have a problem with samsung sp 50 l7h a 50 inch dlp tv


I can see you have a Samsung TV, well the issue seems to be your ballast which doesn't have enough voltage to keep on with your lamp. This is why you keep losing the picture every certain amount of minutes. The thing with Samsung Tv's is that they have issues with the ballast and the color wheel, they tend to go bad pretty fast.

Samsung DLP 72inch, recurring loud pop then fuzz for 3 seconds


I pulled out the Lamp, cleared the dust inside with one of those air blowers and returned the Lamp. That seems to have fixed the picture problems I was having.
