Samsung HP-4252 screen goes black

The device sources and the inputs have not been set to the correct mod.There could be a problem with the TV it's self for it to be turning off like a problem with the power supply for the TV.

replace TCON board.
see procedure at Samsung Plasma TV Repair How to Repair and Replace Main Board

I a feeling that your computers screen is blank because it is displaying to the TV and the TV is blank because it is on the wrong input. Your TV/remote should have an input or source button which you can use to select the appropriate input.

DOES THE TV TURN ON , HAVE YOU TRIED OTHER SOURCES LIKE DVD ,DID YOU CHECK YOUR HDMI CABLE IF ALL OF THIS SEEMS GOOD IT LOOKS LIKE A DEFECTIVE MAIN BOARD REPAIRE ABOUT 325 DOLLARS

It depands if you watch say 5 hours a night times 7 nights 35 hours a week times 52 weeks a year. you be suprise.

Dear Sir,

Welcome to Fixya

Solution:
Generally in all lcd tv you have to select input source in TV menu settings,if TV taking input from AGP,you have to select input as AGP ,if it is composite,select source as composit,if it is RGB select RGB as input by using your TV remote.Then press Fn+F5 in your laptop.
I think it helps.
if you have any problem regarding this issue leave a comment or feedback we were happy to assist you.


Have a Nice Day!

this can be in your video cable or LCD Connector issue. but most problem is in the flex cable of LCD. some other cases cannot be fix and replace new LCD Screen.

Be sure the TV has no problem by playing a DVD player. If problem remains unchanged, call for service because a few boards could involve to. In the worse case, panel should be defective.

You probably have some bad buffer boards as well as a bad Y-main bd and or a bad X-Main bd. Have a trained samsung tech troubleshoot the set.

This is a screen address failure from part of the matrix addressing. This can be caused by fair number of types of faults to cause a missing part of the addressing. You will not be able to fix this yourself.

Find out who the authorised local Samsung service is for your area. They will be able to give you an estimate.
