Others wondered if I had checked vertical and horizontal pulses and I
did see them at the convergence board. Same with clock, data and I2C
buses.

Like I said, I do get 2 good signals out of module prior to the
STK392-110 (desoldered at this moment), other 4 has bad signals or
flatlined.

I tried to adjust by playing with convergence in service mode, and
everything responded to remote but the signals on scope did not change
at all. I have feeling it is the T7K64 IC or four of PCM56PL DACs are
the problem.

In mean time we sent off request for parts numbers and prices and
Toshiba responded back:

QH001 (T7K64) available and quoted $64.78.

PCM56PL (DAC, DIP package, I needed four if I must.) 48.56 each.
YIKES!

Convergence generator module, *DING!* NLA.

For this? On a not too old TOSHIBA 1999 Projector with PERFECT CRTs?
I can get new parts from either samsung (more than 3 to 5 years old)
and RCA to keep old projectors (PTK195) going.

I have a feeling this have to do with the T7K64 IC is partially
failed. Your Opinions?

I have to make estimate shortly that I have done much of
troubleshooting and narrowed down to few possible problems.

By the way: Toshiba, THANK VERY MUCH FOR 200+ settings to record on 4
pages paper before I zapped the main EEPROM. Took long time, either
Samsung or RCA is already done in minutes with paper and chipper
checker or by hand. The convergence's EEPROM data isn't resettable
(to defaults) via menu far as I can determine.

BTW, thanks for the service manual download site, this helped!
