Wayman: you can try the 3 resistors and if that restores the picture then
you know it is the I K circuit problem.
Here is one other tip I found in WinSTIPS. As you can see it is not the
exact chassis, but may apply to yours. HTH

I tried this on a KV32S15 and it does work, value is not critical, I used
three 27K resistors. Like Jeff said, the picture fades in as the filament
warms up like a normal TV used to do and also the sleep/timer led no longer
flashes as it warms up. This is NOT going to fix the weak gun of course but
in some cases the owner could get another year or two out of the set this
way. Finally, a simple way to defeat the IK problem.

In follow-up to me earlier post on the IK Bypass , another tech had
mentioned this method.

Take three 18K resistors and connect one end of each to the Red , Green and
Blue Cathodes , the solder the other ends all together.

This works perfect , you can see the image come up as the filaments warm up.

Image looks like crap because of the dead green cathode BUT picture is not
flashing....and that is all the customer wanted..

> Hi Guys: Have asked for help on this one before and feel sheepish to ask
again. Its on a Sony KV35S65 Chassis # SCC-S07M-A.
> The set will cut the high voltage off and leave the sound on after a
minute or less. Thereby losing any other voltages derived from the flyback.
No fuses blow but sound and station selector work changing channels is OK
too.
>
> I have checked the voltage feeding the I.C. 351 which generates the
horizontal drive, thinking it might be being cut off, but Pin #34 keeps the
9V. on it. I then replaced the IC351 chip and no change. When this happens
you have to kill the AC input to the set so that it can re-set. Then you can
go thru the whole thing all over again. I have tried changing the setting on
the screen control and it works OK for a minute or two. The whole problem is
that I dont have any clues as to whether it is the HOT or the Driver
transistor or the Flyback or some condition that cuts the drive off.

certainly appreciate some help. I have had this set for months and the
customer has another set and a lot of patience.

> It might be an IK problem(but I dont think so) and it might be in the
Automatic Brightness Level circuit but I cant find anything wrong mostly
because when the flyback quits there is nothing to check in these areas and
there isnt enough time that it works to find the problem. The Regulator
Keeps a constant 135V. Regulator was replaced. I replaced the driver
transistor but havent replaced the HOT.
