Fault with the main power supply regulator 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.

    Thanks to the Knight for your help... power board inspection revealed 852 capacitor rounded on top... but the board was also brown around it like a burnout occured... the resisters in that area did not Ohm out so will go with a new board. Thanks for the link.. found valuable info on my model with pics of all the componants.

SOURCE: Blinking red light

It appears in all cases that the power supply needs to be service. The blinking light might indicate that there are shorted parts or the voltage is low or a combination of both.
The solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

My Samsung LN40C530 F1F just went out last night no power nothing I had it plugged into a surge protector, I tried an alternate power outlet I just purchased this TV last year July 10, 201.


Try without the surge protector.

Sometimes the power supplies go bad (could be your issue). Sometimes the back-lights go bad and it will seem like it is powering on (red light goes on/off) and you get audio but no picture.

You will be better off getting a new one rather than getting this one fixed. Unfortunately, sony and samsung are the best two brands. You can try calling Samsung to see what they will do for you (so close to your one-year warrantee).

Good luck.

We have a Samsung PS50Q91HDX Plasma Tv which is not quite 3yrs old. Ever since we have had it, it turns itself on & off at random but this is not the main problem. Last night we were watching a show...


This is weird. I also have a plasma 50" model PS5Q91HDX and on the 5/02/11 the screen went blank when my friends daughter was watching a Wiggles DVD. The image kept coming back, flashing a scene or two before going black again. But the sound is perfect.

I wonder what is going on? Is anyone else having trouble with their 3-4 year old Samsung 50" TVs???

Lost picture on plasma tv


Check the power board for any domed capacitors. Replace them. If this does not fix Replace the power board. You can check the voltages from the power board. they are labeled. VS and VA voltages are the panel voltages.

We had no control of the DVD that we watched last night. No pause, fast forward, etc. Tonight, trying to watch another DVD and the one from last night continues to be playing and will not eject. Neith


Sometimes when you unplug the set ffrom the wall power or a while 1-2 minutes, and then plug it back in the problem will resolve itself. The DVD may eject. If it does, check it for damage, warping or dirt. If this does not fix it- you probably should take it to a repair center.

My tv turns on but no picture or sound


power pack capacitors have failed they will need to be replaced with new ones and that should repair the tv, soldering skill is required to do this or replacement of the entire power pack.
