Re: My first foray into Old model TV repairs.
I’ve got a couple of sets that also have that strange distortion when first turned on, one is an Ekco that I fitted a Mullard tube into, with that one I just turn the brightness up full which clears it in a couple of seconds, then turn it back to a normal viewing brightness. I don’t see it as a problem, just a quirk of old CRT’s. I also read somewhere that using anti-static foam cleanser on just the tube face can help keep static charges from building up on the CRT, but I’ve tried it on the Ekco and it didn’t seem to make any difference.
