When powering off with remote, TV goes to another channel.

[Jim Lazzaro]

I have this Masuda S25TXS ctv-8259 whitout the original remote;
I am trying to use a universal remote (auto search) which does make
all the controls respond except for the power on/off button: when I
power off it does click but goes to a spare channel(just snow) and
when I power on it clicks and returns to the channel I was viewing
(with sound and picture, it acts as if TV turns on from an already on
state).

Which one is most likely at fault? the universal remote signal code or
the standby function of the TV? Please help as I need some real
expertise here before I venture into purchasing another remote.

Thanks
Jim

Hmm did you go through all of the possible combinations? I was using a
universal with a JVC for quite a while with the #1 not working. When
I had to reprogram the remote i ran past the original code at about
#62 and found another combo that worked at # 99. That one worked
perfectly.

My guess is the TVs switching is faulty, but the only real way to tell
is to try another remote. Most dealers would allow you to buy and
bring back if not the solution, explain the circumstances.

Thanks for suggestions, I followed the standby back to an IC
(CTV322S)and tested components nearby but found nothing faulty; only
replaced a sus cap by using my trusty ESR meter.
However Frank is right about all other function on the remote do
respond when the TV is on a spare channel (presumably now in the off
state) but each one of them act like a swith because they make the TV
come on as normal.
I wonder where to narrow my search. The rely is obviously responding
so I will check further in that section.

Hello Franc and thanks for your input, I had another quick search for
faulty components and just as you said I found a shorted transistor. I
have run out of time but once I complete the repair I would like to
report back to all;

FWIW, that appears to be a mask ROMmed uC:
