Just wanted to pass something along for some of you guys that may run into some
of these newer Toshiba.
I had a 36" in yesterday with "No Blue" Found Q905 shorted which is the Blue
Drive. I replaced it, and restored my 182 volts to the collector which feed
thru a resistor directly to KB of the CRT (Blue). I checked right to the CRT
socket and found about 180 volts there. Don't let this throw you in your
Servicing...there is a 1K resistor between Collector and Blue Cathode, (R903),
and unless you actually remove the CRT board from the CRT you will see 180
volts on the other side of that resistor. I got this directly from
Toshiba...and I'msure it will relate to your R or G also. Mark it down in yur
book. Anyway...replaced R903 (1K..1/4 watt)...Problem solved. Toshiba figures
that this gun may have shorted taking these components out, I cleared the Blue
gun with my Sencore CR70...just in case. Set was 1 month short of the 2 year
warranty.
