Short circuit on the "Y" sustain board

Do you know what would cause the "Y" sustain board to short circuit on a Samsung 50" plasma television(PS50C96HDX) that is only 2 1/2 years old?
A couple of days back the tv screen went black but there was still sound,the tv repair shop has said the Y Sustain board has a short circuit and will need to be replaced along with the upper and lower buffer boards...which is gonna cost quite alot to fix.
Any ideas what would cause it to short circuit when the television is not very old?

    Thanks for the reply...... I posted this question a couple of months ago and since then I contacted Samsung who took the TV in for repair....Only charging for labour costs(The parts were going to cost nearly £300 and labour was going to be £75) but after waiting 2 weeks for them to fix it when they said it would be done within 10 days, they then said it was going to take another month to get the parts....after complaining alot to them they decided to give me a new tv...which is better than the one I had.....So if anyone else has this same problem after warranty runs out contact the manufacturer you should hopefully at least get it repaired for a lot less than a repair shop.

The problem is heat!!! If the tv has fans they should be checked for normal operation,although on the early samsung models there were none, and the problem is that the panel drive buffers are getting to hot due to inadequate cooling. This is most apperent when tv is mounted to close to the wall, also external fan blowing on the rear left side will dissapate the heat. It is a problem on early Samsung and Electrograph 42 " plasma models. Hope this helps.

Did it work with the Y-sustain board replaced? Likely if it did not work then there is an issue with the capacitors on the Y-sustain board and the power board. Check these caps for failure and replace them with the exact type. Likely the caps are blown and cause voltage loss in one or both boards.

My Samsung Plasma TV Hp-T5450 turns itself off. I have power connected through extension cord to power outlet. Is their a software fix for this problem?


There should be sufficient reason for this shut down. If any sustain board has short circuit with it, this should happen. Being a Plasma TV; it will be best to contact either the authorized service center for your Brand TV; or any experienced service technician. Normally; a user can't do anything with this fault.

I have a samsung ps50c7000 plasma tv that is powering on/off every 5/6 minutes.


If it powers On/OFF; repeatedly, surely there is a short circuited board inside it. Most likely, it can be Y-Sustain drive board. But, make it sure is somewhat skilled work, that a normal user can't do.
I advice you to contact any service technician in this case. The best thing is to contact the authorized service center for Samsung.

It can be bad power supply or shorted circuits in the sustain boards which will cause the power supply to go into shutdown mode. You need to open it up and inspect those board for bad caps, blown fuses or burnt parts, Most failure in the PLASMA TV are due to bad power supply, failed Z-sustain Y-sustain boards.
