Help needed for JVC FX1100BK tuner

earsandeyes · 22nd October 2005, 09:06 AM

I have a faulty FX1100BK. After years and years of good service it
drops out after a few minutes of playing. I did find a part of the
schematics on the yaho tuner site.

If I do DC measurements out of the "regurator" board (not on the
schematic) into the powersuply part of the main board (on the
schematics)Iget DC readings way above the indicate ones. Some parts do
run very hot.

Does someone has the full schematic of the "regurator" board
available, or even better the complete service manual?

Any other help or suggestions would be welcome.

Regards

my first suggestion would be to go in and do some soldering at the regulators and the output section. loose components will drive one crazy.

The Schematic is available at:
Tuner Information Centre

Thanks for the directions of the schematic. Problem is that the one you will find there is not complete. The people from the JVC service centre were so kind to send me the complete set as PDF.

Still having problems though. Replaced some parts that seemed faulty (leaking caps). No succes.

The schematic is hardly legible. Have put the thing aside for a while now. I asume there is (are) zener(s) faulty, cannot read the right values.
