Hi,
I've got from my friend LG 50PM670S Plasma-TV which doesn't start. (Standby light on, when press power it goes for sec of..)
Replaced shorted Q404: 30F126, Q509: KF7N60F:, Q403: 30F126, D402: SF20A300H and few small caps
from Y-sus board (EAX64282201). Some screwhole shorted to ground (fixed it tape)
Now I hear a faint buzzing, logic board green led is on and center board where flex multiple flex cable goes it green led blinking sequence. Also chips going to warm to touch.
Checked VA+VS+5V+17V voltages there are OK, also resoldered coils and transformers.. (checked Y buffer board cap voltage, it was ~5v)
What to do now??
