Buck if you've got another keyboard, plug it in and see if that works. Also
you might check the board around the CPU, eeprom and keypad plug for any
spills dropping down from CRT. Peter K. pe.kow@xxxxxxxxxxxx Keith's
Stereo Burl On and thanks for the schematic looks like the power
transformer may have a shorted winding---should have about 22 v on either
side of hi secondary, getting closer to 35v

Set brought in no power. Replaced F/B and H/O , ran set for 6 hours on
bench. Customer picked up on Thursday. He returned with it on Monday. It is
some times interment and won't start. When it does start it will run for
15-20 mins OK , then it will start to change channels every 1 or 2 secs, you
also lose any control from the buttons (ON/OFF) etc. There is a connector
that connects the front panel control board to the main chassis. If you pull
the connector from the main chassis it will stop changing channels and will
stay on the last one that was there before connector was pulled. It will run
fine from that configuration..
Changed the EEPROM, checked soldering,checked switches on front panel and
all to no removed remote receiver and still same. I haven't done the tuner
job yet, so I will try that tomorrow
Anyone have any ideas on this as its got me baffled.
