Hi All,

My G70 have been serving me well and all of the sudden the red colour become expose out of other colour.

It mean it used to be a thin line and now become very thick. When I go to the MG focus I try to focus all and it from round flare it become 1 straight. No longer round anymore. It seem the the round flare and core disappear.

Is the the focus board problem or convergence board. Only Red colour.

Appr 3000 hrs non tube and chassis. Tube condition 8/10.

Please advise.

It most likely is either the focus driver/V board, or the focus output board which is hidden underneath the internal keyboard. your tube will be fine.

I can repair that, but I'm out of town for 2 weeks as of this afternoon. Email me at curtpalme at shaw.ca.

Hi Curt,

Thanks for your quick reply. I switch on the PJ last night and it back to normal again.

Once it happen again I will check which is the problem board.

Thanks

Hi, the problem resurface again. May I know where can I locate the Focus Driver/V board or the output board?

Thanks

they are under the internal keyboard. that's the output board. The driver board sits vertically beside the red tube on the outside of the chassis.
