Thanks Max, I haven't seen that CPU yet but as soon as I do I will send
the $14.00 to you covering the EPROM too. Many thanks for the
convenience; I live in the boonies here, 80km from Ottawa, 40km from
Cornwall.
on the Garry River. Alexandria is in the Township of North Glengarry
North Glengarry is a township in eastern Ontario, Canada, in the United
Counties of Stormont, Dundas and Glengarry.
According to the 2001 Statistics Canada Census:
Population: 10,589
% Change (1996-2001): -2.0
Dwellings: 4,509
Area (sq. km.): 642.38
Density (persons per sq. km.): 16.5
Alexandria was settled in 1794 by forty families who emigrated with
Alexander MacLeod and, subsequently, blended with the French culture of
the area to the east. The community was originally known as Priest's
Mill in tribute to the grist mill founded by Reverend Alexander
Macdonnell and which still stands on the site. In fact they recently
started renovating the mill, the opening of The Priest's Mill restaurant
is sometime in August.

David I will send you a 223940 (pre-programmed). $4.00 should cover it.
I hope I can find your address again.

I tried another EPROM from a CTC177AA2 chassis, it didn't work, but if I
remember correctly that TV had a system control problem at the time,
probably the EPROM....LOL.
I'm sure I'll find one. If anyone has a known good EPROM to send my way,
don't be shy. BTW are these things preprogrammed?

I don't have Chipper Checker but I will get my hands on another good
EPROM. Do you know where I can get a pre-programmed EPROM? In Canada,
near Ontario would be nice.

If the data never stops after AC plug in the EEPROM is defective. The
micro is asking for the data from eeprom until it answers it keeps
sending data
Change or reinitialize the eeprom with chipper check Robert

OK, just got back to this dog today.
I have (5V) data activity on pins 5 and 6 of EPROM. Data is always
active, it never stops after AC plug-in, and this may indicate a bad
EPROM. Also I'm not too sure about U3101-5 (KD1 pin), schematic says
voltage should be 0V; I'm reading 5V off the pin (disconnected from the
PCB). I can see how the panel button matrix works for CH UP, CH DN and
MENU but I can't make sense of POWER, VOL UP and VOL DN. How does
U3101-5 (KD1 pin) work for those buttons that don't seem to work?
Perhaps I have two problems here.
Looking for input on this as I've never done a system control problem
before.
Thanks techs,

look for +5 volts on pins 5 and 6 of eeprom if not there or low, replace
it
if ok at pin 8. If +5 ok all pins look for data momentarily on pin 5
while
applying ac power

Hey Gang,
I need a troubleshooting chart for this TV, a schematic would also be
appreciated, any tips out there? Fuse and HOT good, SMPS fires up when
TV is plugged in. I use to have lots of information on the CTC187 before
my other computer crashed. What did I learn, back things up on to CD!
Thanks,
