Re: Sylvania lcd tv model ld370ss8 works fine for 30 min, then shuts off



Let me see what I can do for you. If I have to, I'll draw a schematic of it all and clearly mark what is hooked to what and where everything else leads off too....

Re: Sylvania lcd tv model ld370ss8 works fine for 30 min, then shuts off



Would this be the main board, correct? If so, how do I force the psu (and what is that?) and the back lights on with the main board disconnected?

Admittedly I am a novice at best at this. And at the low end. So, laymen terms would be great. I was required to take an intro class to electrical engineering, so I know at least what the components are supposed to do and how to make readings, but beyond that, these boards look like its from an alien spaceship to me.

The whole set shuts off. Green light goes out, red stand-by light comes on.

So, the tv turns on and operates just fine. Runs for about 30 minutes, then shuts itself off. I can then immediately turn it back on. However the length of time shortens, to maybe about 15 min? And then I can again turn it right back on.

I have read thru all the threads on this forum concerning similar issues with like sets, and have checked all of other fixes, including:

The wires that connect the bulbs to the transformers arcing. I made sure they were separated and not touching, and placed cardboard in between the wires to make sure there was no arcing. Still shut...

Re: New Members - please post your introductions here

Hello everyone.

I have very limited experience with electronics repair, but love to dabble. If I know the issue, I am mechanically inclined enough to do the repair. But, as a civil engineer, I have only had an intro class to electrical engineering. Rumor has it that is only so I can pass the electrical engineering part of the EIT exam. So, enter me tracking down this site and joining.

I really enjoy electronic problem solving, and want to hone my abilities. I'm here to do just that.
