Samsung TV won't turn on. Red light is solid, won't blink when pressed. All capacitors seem fine (none swollen or vented).


That model is covered under a class actions lawsuit settlement over bad power supply boards. You need to contact Samsung about this and get a warranty claim started, even if the original warranty is over the settlement terms will cover parts and labor. You can get additional information about this along with contact information here: http://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/

Samsung plasma tv made a really loud pop and the screen and sound do not work but the red power light won't come off unless the tv is unplugged what happened?


The main power supply regulator board has the fault. Check if any electrolytic capcitor/s has bursted out. Replace them if any. If this do not help you. repalce the board as card basis.
Replacing it as card basis is fine, rather than making 'surgery' to it.

Samsung T220hd won't turn back on from standby


Power up issues on the T220HD monitor are caused by a failure of the capacitors on the IP-49135b power supply board that this unit uses. The repair is easy, you just need to replace the 7 failed capacitors and the unit should be as good as new. Here is a link to some information showing what needs to be replaced to repair the power supply board.

I hope this helps.

Hi all i have a samsung 42inch plasma and i have sound , no pic ?


Your info doesn't indicate if you have a good onscreen display or not. If you do the problem is highly likely to be on the IO board on the rear patch panel of the tv. Replace this board and it should take care of the problem.

If you don't have a good on screen display the two common problems are either on the power supply module or the digital control module. Samsung is known to have problems on both these modules and an electronics technician should be able to remove these modules to inspect for cracked solder joints, or out of tolerance electrolytic filters.

If these conditions do not exist on either board then the power supply board should be replaced first before replacing the digital control board. Search for a vendor that will offer you a full refund will a small restocking fee if the board does not take care of the problem.
