Broken Cap on PCB board
billthesage:
Hi Guys I have an 11ak45b5 sharp with a disintegrated disc ceramic cap connected from scart 2 pin 20 to ground. Its a sharp 28lf92h model and according to manual its a 150 pf but lots of values on manual are incorrect on chassis fitted to this set. It also has a samsung tube fitted which isnt on manual either.
I need to know the correct value of cap as broken one is unreadable :c017:
Bill.

Update fitted 150pf cap according to manual but still have a picture fault. Original fault was R613 burned out and C 623 next to it melted. Replaced both and also eprom now have line tearing and set cutting out intermittently. It could also be described as cogging on verticals. Has anybody come across this before and cured it.
Best Regards
Bill

R-613 (47R or 33R)
C-623 (820nF)
Check Q-602 (BU2508),Q-600(BUK444-on EW sector) and diode D-611 and D-625
