EuroSX4:
Alright So i Replaced 5 bad capacitors and now The tv led changes color to yellow.However no pictures or sound.Anyone have manual or way to check other issues??

Ohm Supplies:
Hello,

Do you have a steady stand by voltage?it could be that the psu isn't switching from the main board. Does the psu have any markings on?
How come you only have 1 entry against your name by the way?

Regards
Andy

EuroSX4:
 Sorry to bring this thread back from the dead.I have been busy.Well I noticed the capacitors i replaced were bulging but now looking at other capacitors on the board no others are bulging but they all have a black sort of dried substance on top.Possible the rest of the capacitors are no good??and all need to be replaced.I tried looking for a power board for this tv no one seems to have it in stock.

 Part number of the psu or board is 5604230Q01-W manufactured by HIPRO

Also how can I check if I have standby voltage??Anyone have schematic to this tv??
or any manuals.

EuroSX4:
anyone experience this problem??I should say this tv has no raster.Meaning the screen does not display a image.I cannot find a replacement power supply board anywhere.

SlyAKs:
You say a lot of the caps have a black dried substance on top of them.. Sounds to me like they have been leaking.. No?  :dubbio: Try replacing those that have this black stuff on them, then go from there. Post a pic of the psu and caps.
