Samsung LE40B550A5 near disaster

(1/2) > >>

sinclairtv:
A customer phoned to say her 40" Sammy was going off so mentally rubbing my hands I quoted her for the repair. Turns out it wasnt the usual type of PSU but a PSU/inverter combi. I thought that the mains input socket was faulty so I removed the PSU. BIG MISTAKE as all the tubes then came out of the inverter board.
I had to replace the panel, turn set on to back and completely dismantle screen to pop the tubes back into the sockets. I really dont know how you are supposed to remove the PSU without the inverter as they are attached.

daz:
thank for the warning

how about a pic of the inards if youve still got the set,may help my memory as im sure to forget the warning and do the same when i see one
thanks

epi:
Any more info on this PSU/Inverter combi, only seen smaller sets with this type, code? photo?
Found no info on the web. :brinda:

Kilroys:
Are we talking about power/inverterboard BN44-00264C.
Screw off 4 black and 1 blank then push the board against the mainboard,
not the small ones that is for the tubes holder.

 :c017: Kilroys for the info, I've located a schematic, check downloads if its not there, I'll upload.
