Check if fuse F5700 is blown. Replace if necessary and then replace C5709 if fuse is blown.

Let me know if it works. If not, we can check other things.

    HOw do i go about checking this fuse? Do i need to take off back panel of TV? I have the manual but don't seem to find any info in it there regarding this fuse.

    Yes, you have to remove the back cover.
    Be sure you disconnect mains first.

    Have taken panel off but can't located the fuses you are talking about. Please point me in the right direction if you can.

Samsung plasma tv flickering


It is 9 years old and old technology being plasma. You have too many individual problems that makes it uneconomical to fix. Time for a new one.

My tv has sound, but no picture. When I turn it on the blue light blinks eight times and the screen is black. What is wrong?


Hi Tammy,
Please check the INPUT of your TV by pressing INPUT, SOURCE or TV/VIDEO on your TV remote. Once you press one of those ( that was on your TV remote ) you should have INPUT lists on your TV screen. All you have to do is select each one on the list until you get a picture ( normally input is TV ). Hope it helps.

Plasma has no picture but sound works???


If the set was struck even a moderate blow anywhere near the screen you may have a bad plasma display panel---the diffused picture sounds like that.

Hi, I used to be a TV Technician and I am considering buy a Samsung PS50Q91HD 50"Plasma TV with an alleged Power supply problem. Just wondering how difficult that would be to replace and how...


I would not advise you to buy a non working TV specially when Plasma is moving out and the new technologies with 3D- LED is around bringing the prices down.
Also the cost is not the factor but if there is fault on the mother board then you are stuck and would have wasted money on a junk. So please do not commit UNLESS you can source a power supply unit - SMPS unit - and make sure that it is the ONLY issue. Let the TV work and then after seeing a good picture you can take tbhe risk... but the cost is also important and must be checked out.

Does anything come on the screen? Input display box? 
If no:

Help - 15 mth old 42" edtv "plasma" black screen" have power and sound


First thing to check is if the back lighting has just failed... Power the set on and looking across the screen can you see a shadow of a picture happening? You might even use a flashlight to shine directly at the screen while you look at it from an angle.
