    I have since been advised by a friend to click Fn key along with F5 key. I have done this and it solved my problem.

    You probably assumed that I'd hafve done this.

    Thanks anyway.

Blue screen is usually a default screen when there is no signal. Check to be sure that you have selected the correct input and that the computer resolution is not beyond what the projector can handle. If you still have problems, please update this and we'll look further.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

I have a 2001 sony 53' rear projection tv model #KP-53HS30. It seems has a wavy section on the upper left hand corner and lower right hand corner of the screen. All the bulbs are working fine but seems...


Try this. The follow was found on tv-forums dot com by Zyntar...
There is a secret service menu to converge the Sony KP53HS30.
Caution: Be careful, there are many settings that can be tampered with. Some may be hard to undo.
Procedure: (use the remote control for these steps unless noted)
1. Turn TV off with System Off (under flap on remote)
2. Press: Display, 5, Volume +, then Power. If successful, service text will appear on the screen.
3. Use 2 & 5 to select the PJE Category.
4. Press 9 to get to fine convergence adjusting.
5. Press 6 several times to get the convergence screen of choice. I like the grid.
6. Use the remote's arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color. Press 3 to change color to adjust. When done, press center of joystick again.
Note: Try to keep the grid even and squared up.
7. Repeat steps 5 and/or 6 for all parts of the screen that need it.
8. Once done, you need to save your settings. Press: Mute, Enter. Then on the TV, press "Flash Focus"
9. Turn off power.
TV is ready to use.

I believe the blue lamp in my 57H81 is going bad.


You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips.
Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.

4) Press 9 - to get to the convergence adjusting.
5) Press 6 several times to get the convergence screen of choice. (I like the grid)
6) Use the remotes arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color(Push it sideways or up and down and hold). Press 3 to change color to adjust(red, green or blue). When done, press center of joystick again, this will turn it back to white.
Note: Try to keep the grid even and square.
7) Repeat step 6 for all parts of the screen that need it.
8) Once done, you need to save your settings. Press: Mute,Enter. Then on the T.V. press "Flash Focus" (it will set it self)

SONY PROJECTION TV TROUBLE SHOOTING BLUE SCREEN


This was one of several Sony models that had bad picture tubes--the set uses a red, green, and blue tube.

There is something easy you can try that may help you get some more life from the set.

SONY SCREEN ADJUSTMENT:

Here is what you need to do.

1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.

2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)

3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.

4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.

5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)

6.)Usually the GREEN will be in the middle.

7.) Once you locate the BLUE screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Screen control.

8.) Best way to do this if the set is on is on a video input clip_image001.gif with nothing connected--you turn the Blue screen down until the set stays on and then very slowly turn it up until you see a slightly Blue screen with or without diagonal trace lines----turn it down slowly until the Blue screen and trace lines just disappear.

Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the screen down a few times to get it to stay on.

If it works you may only be buying some time--if the blue tube caused this it may return at some point.

If all this information has helped you rate this solution as I do this here for free.

The Screen looks 3D & Colors don't line up on my big screen????


If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

Color alignment


Your TV most likely a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • 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.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
