Re: sharp lc32bt8ea

What's the part # on the power board -- a schematic or parts list might be available.
Picture of the diode and the region around where it is found would help too.
It's rare for a diode to fail open circuit - not saying it doesn't happen but short circuit is at least 100x more common.

Re: sharp lc32bt8ea

Is the stby led green ?
Tighten the 6 screws that hold the inverterboard.
very common.
Not !!!
Lamp error caused by the crystal X3001.
Second line should NOT read KDS 6D or KDS 6E
if it does its a bad crystal
Try to get into the service meny.
Is the led red ?
Could be IC708

Re: sharp lc32bt8ea

Sorry, not ic708 course you got stby 5 volt so
the power supply seems to work.
What happens if you press the power switch to ON 2-3 sec.
Nothing.
Try then to get into the service menu.

1- Unplug the AC power cord of TV set to force power off.
2- While holding down the “VOL (–)” and “INPUT” keys on the set at once, plug in the AC power cord to turn on the
set. The letter K appears on the screen. (Factory mode)
3- Next, hold down the “VOL (—)” and “P ( V )” keys on the set at once. Multiple lines of orange characters appearing
on the screen indicate that the set is now in the adjustment process mode. If you fail to enter the adjustment process
mode (the display is the same as normal start up), retry the procedure.
4- To exit the adjustment process mode after the adjustment is done, unplug the AC power cord to force off the
power. (When the power is turned off by the remote controller, unplug also the AC power cord and wait for 10
seconds before plug it in again.)
5- To remove “K” mode, just repeat steps 1 and 2. This time the letter K disappears from screen.

Still nothing ?
Is there not any signs of green led when you start the tv ?
