I was hoping that someone here might be able to tell me the value of
R9610 on a Mitsubishi TV.
I just replaced the vertical IC401 LA7838 and C458 100 MF at 35
volts, but the vertical is still not working. I am assuming this open
resistor is the cause. Just for the archives, it's on the circuit board
which is mounted to the right rear of the picture tube, right next to
the switching transformer.
One Technician suggested I also check C9160 and C9140 which are also
next to the switching supply transformer, and Two zeners off pin one of
the vertical IC. He mentioned that on similar models, if they are bad,
the vertical IC will keep blowing.
Thanks, Dave

PS. The VCC for the vertical ICs on many Mitsubishi TVs comes from the
switching supply rather than the Flyback Transformer.

I think I can answer my own question here, a similar model Mitsubishi
uses a 1.8 ohm 5 watt resistor for R9610, so I hope its the same.
Unfortunatly it didn't fix the problem, but if I can figure it out, I
will post my repair tip here.

It turned out that the new vertical chip I just installed was bad.
Just some additional info, I believe that R9610 is a 3 watt resistor,
not a five watter, and ONLY 1.6 OHMS. It was also suggested that I
replace all the caps next to the vertical IC, and check for shorted
zener diods in the same area. If they are shorted, I was told that
your new vertical IC will blow out.
I hope this info helps some one.
