| The tube. G2 sounds ok. Stick a hv probe under the cap of the flyback and see what your voltage is. If it's around 20k,,, I'd suspect a bad picture tube. | |

| Hi Guys, It.s me again with the RCA ATC113AA Has been giving a Headache.
I started with dim picture i resolder everthing no avail. then turned up g2 have enough bright but get bad poor covergency on greens. when i turn down the G2 to the rihgt level where i can get a good pic and convergence,then when turn off set then turn back up again the pic is dim or without bright,i have to keep the G2 a litle bit higher thus degrades the green convergence,I don't have sckematic, i suspect either FLY or IC TDA6107G Video Amp, any ideas thanks in advance. Took measurements of the IC Drivers Amp TDA6107G , Unplugged the CRT board from the neck of the tube, turned on set. This were the measurements Pin #1=1.6v,2=1.5v,3=1.5,4=0.00, 5=5.00v,6=193v,7=160v,8=160v,9=154v, I plugged in the CRT board in the neck of the tube, turned on set. P#1=1.9v,2=2.3v,3=1.7v,4=0.00v,5=5.00v,6=192v,7=150v,8=119v, 9=139v,all this was taken from the hit sink G. and with no RF connection also Measured G2 on the crt board while i was turning up and down the g2 control, minimum control 151v,maximum 380v |
