Megatouch type 58 monitor wanted new

Chances are thats a Tatung VGA monitor. I have a spare untested chassis somewhere, but if you have any electronics skills at all we may be able to help you troubleshoot it.
 
I have two 58 monitors but both have a not bright picture. No burn in just dim. Thanks Ron

There are no tubes just a picture tube. What is a rejuvenator? Will a rejuvenator help to make it brighter? Where would I get one? Thanks Ron


A rejuvenator can clean the guns in the tube making the picture brighter. A cap kit on the chassis may help brightness issues as well.

They can be found on ebay, or someone local may be willing to let you borrow one.
 
Type 58 monitor

Have the brightness OK at present. Does the two adjustments on the flyback tranformer help with brightness? Does anyone know where there would be a focus pot on the chassis to get it sharper? Thanks Ron

There are also 3 pots on the back of the picture tube on a plate. Would these help fine tune focus? The flyback did sharpen the focus but not quite enough. Wish I had a pic to include. Thanks Ron
 
Those three pots control the individual guns on the tube. Don't mess with those unless you have a single dim color.

How bad is the focus? As the tube ages, it's going to get dimmer, and lose focus. Other things can cause low focus voltage though. Can you turn up the SCREEN control to get it bright enough without creating retrace lines in the picture?
