Viewsonic N2635W freezing

[rlee]

I acquired a Viewsonic LCD TV model N2635W.
The unit works fine for a several minutes and it freezes.
And later on it restarts but without the sound.

after turning of the unit for a 5 to 10 minutes , the unit powers on and after freezes again.

any body has similar issue?

Thanks

Sounds like its overheating. Point a big old box fan or something at it and see if it stays on longer?

Thanks for the suggestion. I put a fan on the back of the LCD.. and the TV has been running for 5 hours now without single freezing. .
The fan seems cooling the LCD and preventing the overheating.
Is there any faulty component inside that causes overheating..
I am thinking of installing a small fan inside the TV.

thanks again

Try checking (carefully) inside for the thermally sensitive component. A small cooling fan, a heat sink might do the job, or it is even possible a thermal transfer pad may have been omitted.

I dont suggest messing around/feeling aroun for hot components. You kight get shocked or the tv could get damaged. Just add a small fan somewhere inside...

Ps: lol i was right! Not bad for my first time answered a tv questiom

usually the solder balls break on the CPU BGA and causes just this. you can heatsink the main CPU and put a fan on it, or reflow the BGA with a heatgun controllably.
