How do I fix my Samsung 60" Plasma flat Screen TV


Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Plasma tv takes time to start then picture flickers really badly then picture returns as normaal for a few hours then goes black but still has sound i turn off tv for a number of hours & repeat the...


This tv seem to have two problems.The problems that the tv take a long time the tv to turn on,the tv power supply board have dying capacitors most likely.That the board where the power a/c cord plug into it.The picture flickers badly this problems is harder to determine because this causes by two backlight buffers boards X,Z buffers boards could be either one it is dying.This tv should get an estamate by a shop or shops and repair it by them,bcause the tv must have to be doing replacing x munbers capacitors components to the tv power supply board and alot more work to trouble shoot and to detrmine which of the buffers boards it is the causes of to the picture screen to be badly flickers and replacing it.

Same as ericgustafso. My Samsung HP-T4254 42 in. Plasma TV randomly turns on and off. The short while it stays on, the picture and sound are perfect.


the capastor on the mains power board are on way out check them look for raised tops ( they look like little bateries with white line) if you are going to replace them yourself take picture so you put back same way

I have a 42in plasma samsung and somehow have sound but not picture, need help. Thanks!


This can be from the power supply, main processor, screen drive, or the screen itself.

The modules must be tried to determine the defective one.
