Hello ,
I have Sanyo DP42545 that has sound but no picture .

I got a service manual , but know very little . So here is the walk thru iam hoping to get help with . The back panel is removed , I notice two green led's . One is solid green , the other one , has one that is flashing .

Looked at a couple other things today also if it helps ---

On the main Logic Main/Logic Board ( one in pic ) the circled area in the pic - has 4 leds -- the second one ( from left to right ) marked led2002 on power up blinks a couple times then goes and stays out ... the last one ( from left to right ) marked led2000 is the one that blinks all the time .

Also did a complete in dark test --- the left side of screen will light up - but only very quickly and then its out .

The manual says if no picture check :

line: ic2001 - ic301 - ic7001 - pdp Panel
Parts: Around IC2001 ( DIGITAL DECODER), IC301 (SCAN CONVERTER),IC7001 (LVDS Interface),PDP Panel

well $ 95.00 later , i got an estimate that it would be approx $450.00 to
$500.00 to fix it . I asked what was wrong with it and was told " a main board inside needs replaced " Rolling Eyes
Its kinda big for a door stop but guess thats what it will be now . lol
