[trunks81]

Hello

Got this board and in the begin the next parts where defective

CM810 = 1KV 2.2nf
QM801
QM802
NT811S = DSC_5D15
And the fuse was blown

After replacing these parts the tv worked for like 15 seconds and i had an image, After this the fuse did blow again.

i did replace those parts again and now only the fuse in the fuse closet goes.
Fuse on the board is good.

Perhaps this will help.

Check that the gate components are all ok,RM811, RM813, DM803, Dm804, DZM803 etc. you will likely need to remove one end of the component because of the parallel resistor

Also check BD801S. If only the fuse is blowing then you may well have a damaged bridge rectifier.

Look like the bridge rectifier is defective also,
Iam getting very low ohm between AC (Also when desoldered)
The type is TS4B05G, Can i please any rectifier back ?
