Title: bally gamemaker monitor problem Post by: resanberto on September 28, 2009, 02:13:05 PM Hi all
I need hlp with a gamemaker monitor Horiz size is to wide , you cant adjust it. i suspect a small cap 50v/4.7 uf near the flyback. after replace i can adjust the size back to normal. the problem is after 3 or 4 days the cap blow again. i change it with higher voltage caps and still blows it. :25- Does somebody had the same problem i face here?.

Cheers, Berto You are using a NP or BP cap right ??? Title: Re: bally gamemaker monitor problem Post by: resanberto on September 28, 2009, 05:47:19 PM i use BP type
original is a non polar cap ty, Berto Title: Re: bally gamemaker monitor problem Post by: Jeff on September 28, 2009, 08:12:22 PM It sounds like you have a transistor or a diode leaking. You need to trace back,
and look for a resistor that's probably going to be way off the specified ohm rating, and also withen that circuit you'll probably also find the leaking semiconductor. Regards, Jeff Title: Re: bally gamemaker monitor problem Post by: resanberto on September 29, 2009, 07:35:31 AM thanks joey , jeff.
i replace diode's , resistor's and also the D1138 transistor and still the prob. everything that lead to that circuit you can feel that the cap is getting hot and blow. i have two of the monitor with the same problem. cheers, Berto :31- |
