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.

Hi Baron

I don't have access to service info for that tv unfortunately, but if
it's like most LCDs, the dead set symptom is mostly down to psu
trouble, and most are not that difficult to sort without schematics.
Often, it's just caps, as I'm sure you've seen mentioned on here many
times. You will often find the voltages marked on the psu boards. By
connectors is a good place to look. Typically, there will be a standby
supply of 3v3 and/or 5v. The main switched rails are usually some or
all of 3v3, 5v, 12v, 24v for the backlight supply, and 33v for the
tuner. Occasionally, the odd negative rail.

If it does come down to psu, and you can't fix it, a replacement board
is available here

for a very reasonable price. In the meantime, I will ask my mate who
does a great deal of LCD tv repairs, if there is anything common on
that model that he knows of.

Hi Arfa,
Thanks. I did pull the back off today and as you say the voltages are
marked on the PSU PCB. All the ones that I could identify I probed
without finding one that wasn't correct.

I did note that the red led in the middle of the power button seems to
have a weird flash sequence, so I suspect that its some kind of fault
code, a bit like the BIOS beep codes.

Once again I'm grateful for any help I can get.
Many Thanks.
