Got this free one with a cracked screen. It's hard
to tell, but it's possible only the covering glass is cracked,
and the panel itself may be ok. Story is, the person
won the TV, got it delivered, and it was cracked
during shipping. They delivered another one, and
she gave this one to me.
At any rate, the original owners didn't have the
remote control, and amazingly, in what must be
one of the stupidest engineering decisions ever,
there is no power switch on the edge of the TV
itself! Unheard of! My only guess is that they
were desperate to shrink the size of the TV, and
got rid of the manual controls in the process.
But what the hell do you do when you don't have
the #$@#*% remote?
Anyhow, when I plug it in, a relay clicks, an LED
on the logic main blinks 3 times, and there
is a somewhat disturbing buzzing noise, and then
another relay click, before it settles down, so there
is obviously standby voltage.
The caps seemed ok, but as everyone knows, you can't
tell by looking....but there were no obvious signs of anything
burned out.
In the second photo, I measured PS_ON to be +3.3V, and
STBY to be +5.33. There were no other voltages present
(i.e., no Vs, etc.),
I've read on the other threads of using batteries to turn
on the board, can this be done with this tv? Or does PS_ON
have to be 0 volts for the PS to turn on? Or can you
fool the board into thinking there was an IR sensor signal
for turning the set "ON", with the connector in the extreme
lower right corner of the first photo?
If I'm amazingly lucky, the set will turn on, and the plasma
panel will still be good, and I'll just need a new glass covering.
But much more likely is that only the boards work. But I still need
to at least verify the voltages are present, before I post these
to Ebay......
Thanks in advance......
