Power supply problem Finlandia TV
I've a intermittenly dead Granada/Finlandia TV i.e. nothing when power-on,
except a low buzz.But works alright,if and when it starts. I need a schematic on this 28in TV or an operation manual(especially the front end power supply) before I dismount the chassis (mainboard is mounted on a tilting board for easy dismount) for repair. Any help wld be much appreciated (except suggestions for replacement,that is). Thanks YG |

Did you tried to replace them and see what it does? Al |

TV has gone dead totally since post.I've been gathering info om this make from local lib. & web & is about to open the 'can' with a TV repairman. I reckon that since it managed to servive this long (since 3/90),it deserves to live on.. YG |
