Customer Question
When I turn on...

When I turn on my Samsung model LN52A55 55" TV (bought in 2008), it displays a bunch of pixels, turns itself off and on again, and then displays a good picture. And either the TV or AT&T cable is pixelating occasionally.

Technician's Assistant: Are there any HDMI cables or A/V jacks (red, yellow, and white cables) plugged into your LN52A55?

Yes - 1 for AT&T cable box, and 1 for Apple TV box

Technician's Assistant: Was there a power outage recently?

No

OK, this kind of problem mostly occurs due to failing capacitors on power supply board, in coming days TV may take longer time to get stable and solution is to replace bad capacitors or entire power board in TV.

Please check with following supplier to get required parts/ board if you have plan to do it yourself..

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page so I can get credit of my work on website.
