Re: Samsung XL2370HD 23" LCD TV pink screen then powers off

Thanks for the advice.

Is it likely heat related, since it takes a shorter length of time on each consecutive restart, before it stays off? Can I spot blast main board components, and see if any improve duration?

I've seen flux residue and am pretty sure this is not.

I'll try a cleaning and check the screws.

TorqueMaster here. This is my obligatory introduction. Trying to fix a tv and this is required to download some linked documents that may help. If not, I'll post a new thread in the appropriate area.

I'm just a hobbyist at component level repairs. If it's bulging, or looks like the factory installed smoke got out, or the solder joints are bad, maybe I can fix it. On rare occasions I might attack with a multimeter. If cheap enough, I'lll swap out my best guess at which may be the bad board. Mostly self-taught with...
