dead flyback?

Best take it to a shop...Sounds like you don't have a Clue. That way you stay alive.

i tested all the others i have here and they all read infinity. is it possible the secondary is shorting out or is this a type of flyback i haven't come across before.

It could be, but it's more likely something else. Do you have B+ at the HOT?

with the HOT removed, and a 40w bulb across C/gnd i get a B+ of

If you measured 2.68M ohm or lower in both directions between the anode cap and anyplace else, the flyback is bad. The resistance should be in the hundreds of M ohmz to infinity range.

i had another look and measured the resistance both ways but now im not getting any readings. the monitor has been inside next to the heater. maybe temp. is affecting readings? i did a few voltage measurements at the crt pins with the 40w lamp across C/gnd. G1 20v G2 167v G B & R 120v HTR 7v

if its not the flyback and i have B+ then what should i look at next?

Even if it was baking, the resistance shouldn't be less than a few hundred M ohms, and probably not less than infinity on a typical meter.

Do you mean HOT C to ground? Not sure what that proves other than you have B+, which from a previous post, sounded like it might be reasonable.

This is probably low, but due to your meter loading the circuit.

If I interpret what your saying here, in cutoff.

Did you try turning up the G2 pot to see if you can get a raster?

i put the HOT back in and tried the G2 pot, no raster. tried a neon globe around the flyback but it doesnt light up. theres a fluttering sound coming from the yoke area(deflection circuit?) G2 on the crt pin has gone up from 167v to 242v.

What would be the point? Monitors are rarely worth paying someone to fix anymore, better to do research and keep poking around, might learn something useful. Seems some qualified technicians have forgotten that they too started out not knowing how to fix things.

I resemble that remark, and had an EET behind me, as well as some radio/TV experience behind me, before I got into the consumer end. There are generic problems, and there are specific problems, and only time and experience will separate them to the point where they are actually separate.
