The convergence ICs located on the signal board will need replacing. This is the board with all your RCA and RF connectors are. You will also need to inspect those low ohm small wattage resistors and check the bottom side of the boards for bad grounds. (These will need to be resoldered) Take this note to your local TV doctor, you have concrete proof, you know what needs to be done.( This can save you a few bucks.) Good Luck and thank you for asking. Show a few hands of support!

convergence issue. Press menu and then scroll down to the setup option enter setup and scroll to Autoconvergence and activate the auto convergence feature that will realign the convergence . If that doesnt correct the issue you will need a Convergence power board, If the auto convergence feature is missing from the setup menu then you need the convergence option missing repair kit.

Can a ps3 cause problems for your tv


If the convergence is normal with VHF antenna or video input, convergence circuit is OK.

If convergence problem becomes visible when you switch to HD input, the convergence needs adjustment for that size or picture mode. Sony TV has different memory data for different size or format pictures.

If adjustment in the customer convergence adjust screen is not satisfactory, someone has to enter the service mode and adjust. Not recommended for rookies.

The game box or any other input will not damage or stress the TV if the game box is working normally.

If convergence is not correct in all size modes and can not be adjusted you need a repair to the convergence circuits.

Occasionally the convergence ICs are on the verge of failure from accumulated AC power bumps or lightning pulses on the AC line.

A small spark from poor grounding or static electricity can occur when connecting an input and the TV is powered on. Semiconductors (transistors, diodes and ICs) that have accumulated junction damage may fail when the effect of the arc is applied to the junction of the semiconductor.

The failures are often blamed on the Game or other external device. The TV would probably have failed in a short period of time with normal operation.

Turn off power to TVs and external devices when connecting or disconnecting video, audio or antennas. It is also important to use power sockets correctly. All electronic equipment has polarized plugs or 3 prong plugs to make sure the grounding is correct. Using multiple extension cords that are not grounded correctly or incorrect house wiring causes ground loops and unexpected problems. Best is a power bar with 3 prong plug in the wall.

My tv is showing at teh bottom of the screen the red and green lines from the projectors , and if a change the bullb how do I focus the lense again


This set does not have a bulb. It has three picture tubes and a convergence correction circuit. Find the convergence adjustment mode in the setup menu. If you cannot adjust the convergence, most likely you have bad convergence IC's. This can be a complicated repair. Have a shop check it out for you. Thanks for using fixya.
