Hi Peter, I had a very intermittent fault like this but I would lose most of
my vertical deflection and all of my audio, and it was VERY INTERMITTENT !
I found the Minus -12V supply off pin 7 (thru a diode) of the FBT was being
lost. Check on the ANODE of the diode for -12 volts. If it is +4 or
something, you may have a bad connection INSIDE the FBT.

Subject: [TechAssist] RCA PTK169BE chas- very intermitant loss of pix and
sound
> Hello all, Have 1 in the shop and 1 out on the road( still in cust house,
ha ha), 2 PTK 169 chassis that have extremely intermittent audio and video
drop out. When it happens, the fault duration is usually about 10-15
seconds. Both sets have been in previously for int pix and have had joints
repaired, components in PS and sweep replaced. Both sets were in last year
and had started to act up again after 2-3 months. Has anyone any insights to
an extremely int interruption of sound and pix ? Also the one set
occasionally seems to reset itself as if there had been a total loss of
power. peter Kowalik pe.kow@xxxxxxxxxxxx Keith's Stereo Burl Ont
