JVC AV-61PRO ON SOME CHANNELS THE PICTURE BOWS IN ON BOTH SIDES AND ON OTHERS ON TOP AND BOTTOM. THE BOTTOM OF THE SCREEN IS CLIPPED AND I HAVE STRETCHING IN ALL FOUR CORNERS. PLEASE CAN YOU HELP

What you are describing can be due to a number of different settings.

Focus on the red and green guns
Sharpness on the red and green guns
Horizontal position and size
Vertical position and size.

Please consult a professional for adjustment on these items as they are all near or connect to parts that have Hazardous Voltage.

the part is called the convergence ic. replace those ics.

These sets have several common problems which are listed below.

Problem #1) Convergence

well take the back off on the transformer should be two adj. pot screen control on top focus on bottom normally try to turn up screen control good luck

most likely a sync problem

It's ring-cracked solder joints on the foil side of the board, most likely in the convergence circuit...

B+ voltages to run the convergence circuit missing == check power supply for open fuse devices..........................T.

civilman, the first set has either no high voltage or is collapsed vertically, until someone checks for high voltage there is no concrete answer, the AV27730 is vertical collapse from your description, either the voltage to the vertical IC is missing or the vertical IC has failed, not a big deal cost-wise, hope this answers your questions, if not e-mail me back, good luck, BMW Rider

unscrew the screws along the sides and top at back. gently lower screen forward and look inside--you should see the gasket--reattach it or remove it...I just removed it after staring at it for a year or more
