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.

"Perfect Focus" problem on Samsung HCN4727W

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

I have a Philips 51PW9303 Rear Projection TV that had blue shadows around the sides of the screen and now has a green and red bowed line at bottom. Does I need a convergence board to solve this?

If the following doesn't work the tubes could be at the end of life:
Adjusting convergence:
Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

To adjust the convergence of the picture tubes:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Press CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT to select CONVERGE RED or press CURSOR RIGHT and DOWN to select CONVERGE BLUE.
  5. A crosshair will be shown on the screen. If there is any red or blue fringe around the crosshair, use CURSOR RIGHT, LEFT, UP, DOWN to try and merge the fringe colors with the crosshair.
  6. Press the 'MENU/SELECT' button to return to MANUAL CONVERGE menu.
  7. Press the 'EXIT' button to exit the menu.
If you are satisfied with the convergence you may stop now. Otherwise, you can continue and adjust the convergence more using mult ipoint convergence.
To Adjust multipoint convergence:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Use CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT on the cursor ring to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT and DOWN on the cursor ring to select MULTIPOINT RED or MULTIPOINT BLUE.
  5. A grid of crosshairs will appear on the screen. If there is any red or blue fringe around any of them, press CURSOR RIGHT to enter NAVIGATE mode.
  6. Use CURSOR RIGHT, LEFT, UP, and DOWN to move to a crosshair that has a color outline.
  7. Press the 'EXIT' button to enter ADJUST mode.
  8. Use CURSOR RIGHT, LEFT, UP, and DOWN to merge the color with the crosshair.
  9. Press the 'STATUS/EXIT' button to return to NAVIGATE mode. Repeat as necessary.
  10. Press the 'MENU' button to return to the MANUAL CONVERGE menu.
  11. Press CURSOR DOWN until SAVE MULTIPOINT is selected.
  12. Press CURSOR RIGHT to save the multipoint settings.
  13. Press the 'EXIT' button to exit the menu.

Dark picture

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

PT5499HD Covergence Akai

Yes, you have a size problem you have horizontal and vertical size. Either its' in the service mode or somewhere on the set, with this set it's probably in menu. Must be set too high. I will look for menu codes! Is this an Akai or Panasonic set?

Convergence chip

Now is this what really is the problem is your friend's have a tech man tell him so? in any case you're looking at roughly $150-300 repair cost plus labor. but you can try the following your self by entering the service mode follow this steeps: Read the _ SERVICE MODE WARNING _ before proceeding. To enter service mode, push and hold the [Menu] button on the set. While holding, push and release the [Power] button, then the [Vol +] button. You will now have some information on the screen: "P0 V0" To actually be able to change these values, you must push [Vol +] on the remote so the information reads V76. Then pushing on the Channel +/- will change the "P" value. P1 - 3 are error codes. If there is a problem with the set that can be self-diagnosed, the "V" will report the code. These codes are available in the RCA repair manual. P4 - 7 control the horizontal size, shift, vertical size and shift. You may also find a summary leaflet for the service tech clipped somewhere inside the chassis. The procedures for getting into the service mode, as well as the service items of interest will be there. If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material. Adjust the problems manually with any luck you might be able to get it back to normal. Good Luck!
