Sony rear projection screen is red then tv shuts off


Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

Bowed flickering green screen, black on bottom


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Go here for all puzzle walkthroughs
Puzzle No. 120 Tap the open manhole above from the Sewers below.
Get the Ball Out! 3: Slide the bottom-right blue block over to the right and drop that lower purple block in the slot with the hole. Now, drop the big yellow block down. Drop the top purple block down one and then reposition the top two blue blocks so they are touching end-to-end directly under the red ball. Raise the left green and the big yellow block up into the center. Slide the bottom-right-most blue block all the way to the left. Drop and slide the other right-hand-side blue block as far left as it can go now. Drop the green block on the right down and into the right-hand nook. Slide one of the top blue blocks to the far right along with the yellow block and the right-hand blue block on the bottom. Drop the red ball all the way down to the bottom row. Move the left-hand green block up into the ball's starting slot and slide the yellow block all the way to the left. Move the bottom-right blue block up and the small purple one that blocks the hole. Now simply put the red ball into the hole.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Top left corner double picture red and green


you have a failed IC resistor usually you can physically see the bad one because it burns out leaving you to guess what the value was. Hitachi offers a convergence fix kit which has 2 IC's and all approiate resistors.

Blue vertical line running down my 42" Plasma TV (42PF9631D/37)


I was not sure if the line was going from top to bottom or left to right. the X driver board is for left to right and the Y board is for top to bottom . The Y driver board is a common issue with these sets there is a Y main board and a upper and lower buffer board for the Y axis
