As you can see , the | vertical size is 1/2 of what it should be and the width is in also.....an | elliptical shaped image! | | Went there yesterday for a basic checkout....didn't have service data with | me....I now do. | | A quick check of B+ levels from the main power supply board revealed no | problem there | | Main B+ is right at 135V , + & - 22V lines are at 20.5 ( should be OK) , + | & - 15V lines are in spec also. | | Disconnecting convergence coils made no difference....just made the picture | unconverged at best! | | If this was an early model set I'd bet the jungle IC was the problem! | | Going into service mode , the vertical size does respond but does not fill | the screen...... | | Looks like the drive levels are way to low. | | Any thoughts or experience on this newer set would be helpful. Going | back Monday with the manual....will pull the tubes and chassis if need be. | No lightbox :-( | | ========================== | Jeff Stielau | Shoreline Electronics Repair | 344 East Main Street | Clinton,CT 06413 | 860-399-1861 | 860-664-3535 (fax) | jstielau@xxxxxxxx | ======================== | "If you push something hard enough it will fall over." | Fudd's First Law of Opposition - Sir Sidney Fudd | | | | -------------------------------------------------------------------------- --- | Lost Password: | http://www.tech-assist.org and select "Login Problems?". | Email Archives: | //www.freelists.org/archives/techassist/ | ----------------------------------------------------------------------------- Lost Password: http://www.tech-assist.org and select "Login Problems?".
