off topic... crt set issues...

S

SFM-Ptgal

My old but not vintage crt set is shooting bursts from time to time... These bursts are a sudden flash and the image becomes softly tinted in sometimes in red, in green/blueish... Sometimes the problem goes, sometimes remains... Not that I know "how to" what can the problem be?
 
Sounds like an intermittent short. Can you test the CRT?
 
Yep, sounds like possibly a heater-cathode short in the CRT ... the only weird thing is that you report that the tint isn't always the same color, where H-K shorts generally affect one color. It could also be an intermittent short in the flyback.
 
It's a very, very soft tint, very random, I can't replicate the conditions to make it happen... most of the time the problem's not even there... The crt is about 16 yo., something impossible to a lcd ;D

Ok... (...)heater-cathode short... (...)flyback Youtube here I go ;D
