Re: Samsung Plasma clicking

I found these great service manuals on the forum. I ran the diagnostics on the Power Supply, and all the voltages checked out fine. i should have checked the voltages on the posts indicated in the manuals, but instead checked them inside the connectors which lead to a very scary spark. It turns out my main board is bad.
Any idea where I can find Samsung PN BN94-018688?
The Power supply was available from many suppliers including China, but I can't find any suppliers for new versions of the main board. the only others I found were on ebay -...

Re: Samsung Plasma clicking

I forgot to mention, the Red LED on the front flashes simultaneously. the sound is usually a high annoying pitch. Here are photos of the boards:

Re: Samsung Plasma clicking

I have the Samsung PN50A550S1 Plasma. All four fuses (2 on PSU, 1 each on X and Y) test fine. I start hearing the music, then a click and various sounds while the TV cycles between off, on, noise, then off again and repeat. No visible cap swelling on any board.

I disconnected the X and Y boards from the PSU and had the same cycle of on, sound, noise, off, etc.

Re: New Members - please post your introductions here

I'm a newbie to this forum. My plasma TV went kaput and I'm trying to figure out what's wrong. I've replaced caps before in my Apple iMac and Klipsch subwoofer, so am comfortable with the process. Maybe someone here can help.
