Twit needs help on Grundig TV

[Anti-Spam]

Having problems with my Grundig "Elegance 70" TV model MW 70-150/8
Dolby. The set kept switching itself into standby, and would reattempt
to fire up again, which after a few goes it managed to refire up. A
friend of mine who is a TV engineer suggested that I change the LOPT
and the high voltage caps around the LOPT. I took them out after
numbering them, took them to a component shop who had most of them
(including the LOPT), got back and found that I am one short of the
capacitors. Trouble is, I do not know the value. The board designation
says "C53572" Does any kind soul out there have a circuit diagram for
this chassis and can tell me the value of the missing cap. TIA. Mark
in Spain.

PS If this is the wrong newsgroup, please let me know, thanks.

LOPT= line transistor or transformer?
check the schematic, see www.eserviceinfo.com. also
post on dudaelectronica.net forum if no luck.

you need the chassis reference of the tv, starts cuc XXXX. look on the
rear panel or consult model to chasis list on cromavideo site.

good luck. b

Thanks B, the eserviceinfo web site I put straight into my favourites
folder, great site. Spent 20 mins. trying to find the CUC part number
somewhere on the chassis, but the buggers have hidden it, lots of part
numbers for the various bits of metalwork and PCB's but no number I
could find for the Chassis in total. Could not find the Cromavideo web
site you mentioned, any chance of the complete address? LOPT I meant
as Line Output Transformer, already changed the LOPT driver
transistor. Thanks for you help. Mark.

B, sorry mate, further investigated the eservice site and found the
chassis number through that, and have now found the part I need to
get. Your help has saved my day, if by chance your ever in Spain, call
by and I will buy you a large drink, thanks. Mark.
