Title: Bad Picture (Wavy)
Post by: DarkSide on January 06, 2009, 05:45:15 pm

Hi.

First off, sorry about my bad english, and the spelling errors there is.

Chassis: Kortek Copy of Nanao MS720L.

Now my question, finally got a picture on the kortek chassis for my sega hang on bootleg.

The problem can be seen here: http://yousuck.dk/sync/ on the last 4 pictures.

The chassis had a complete re cap done, without any change.

Any ideas?

with stationary video, if a slight adjustment of the Hosc ( horizontal oscillator) affects pic tearing .
there may be a small value 'lytic that might have been missed in the osc circuit .
i'll need to look up a print to give u specifics ....

and your english is ok .   ;)
 now , what can be heard on the streets here (USA) is an entirely different matter.    :o
