[TechAssist] 2nd Request: Need SCHEMATIC for ANY TOSH. Which Uses TA1310 Jungle Chip

Toshiba 27" TV
Model CZ27V51 or ANY SIMILAR model
Chassis TAC 9911
2000 Model
I DIDN'T GET ANY RESPONSE FROM SEVERAL LISTS I POSTED TO LAST NIGHT
I REALIZE IT'S A HASSLE TO SCAN TV SCHEMATICS. Maybe someone has a
1999 or 2001 print or even a 19" with the same jungle chip - Just
need a small portion or even a couple voltages to check instead.
NEED SCHEMATIC OR HELP
Bright screen with retrace lines
Screen voltage is normal (and turning screen down causes red smear)
CRT cathodes are around 70V (200V supply is normal). Color output
transistors base and emitter voltage is normal.
ADJUSTING THE BRIGHTNESS LIMITER IN THE SERVICE MENU CAUSES NO
CHANGE. Other adjustments do work
A few weeks ago the CRT went bad (no vacuum) and R216 was smoking.
I replaced the CRT and R216 (with a 22k) and the set worked OK.
I need a partial print (brightness limiter circuit - flyback to
jungle chip) or someone to tell me the correct value of R216 and
other parts in that circuit which may be causing a brightness
limiter problem.
