Does anyone know where I can get service information for a Samsung
LCD TV Model LE37R87BDX.

Google gets lots of hits, but they are all dead ends in one way or
another.

Mine has just decided to switch itself off and sulk ! :-(

Thanks.

OK. Had a word with my mate, and he says that it's pretty much always
power supply caps on that model. He reckons that there's about four
of 'em which will all have blown their tops, and he says it's obvious
as soon as you take the back off. He also said that if it has been a
bit iffy at starting up for a while, then sometimes, it also ****s
the EEPROM, so if there are any further issues after replacing the
caps, that will be the cause.

Good luck with it ! d;~}

There are no obvious signs of any damage. No smells, no burning, no
noise, not that I would have heard it over the program sound. Though
bad caps was the first thing that I suspected.

I'm going to take it into work with me tomorrow and have a look at the
power rails with a scope.

I'll report back. Take care.
Thanks again.


Hi Arfa,
Well I scoped the power rails without finding anything I could report as
useful. The ripple that I did find was around 120mv and that was on
the 33v rail. Some really odd waveforms on other pins, but meaningless
without knowing what they were for. I did note that the heatsink for
the CPU got moderately hot over the ten/fifteen minutes that I was
checking voltage lines.

Stuck for the moment. :-(
