Fix my line problem but red LED flashes five times

Hi Guys, I fixed my horizontal line problem by adjusting the power adjustments for my RGB guns per your web instructions. Worked Great! The red LED is blinking five times (used to be 8 times but that stopped). What does this mean.

    Any Idea exactly which knob it is? They aren't marked. Do you have voltage output levels that I should work to obtain for each gun?

  • dtpatch Jan 27, 2009

    I decreased the power to I believe the blue and green guns to eliminate the horizontal lines that I was experiencing. Occaisionally during this process the screen would flash bright green and the LED indicator lights would blink eight times. The horizontal lines have disappeared but I now the red LED blinks five times

    I think you are adjusting screen volt of 3 guns through a box fixed at front corner near speaker.
    Let me explain procedure how to set power ( screen volt) HV Control has 6 knobs, upper 3 and lower 3, check there mark of SCREEN R-G-B.
    Room light should be low and cover 2 guns lenses with any thing like paper or book and adjust uncovered gun. now cover this and uncover any one other, same adjustment and do the same with last gun.
    Adjust screen volt of all 3 guns up to that level as retrace lines ( horizontal lines) disappear.
    now screen volts has been adjusted and tv will not give you 5 times error.

    Let me know what you had adjusted before at 8 times blinks?

    5 times blinks means poor white balance result.
    Please readjust those knobs of power (screen voltage).

Hi Guys, Looks like your advise took care of the problem. I adjusted the power knobs for each of the RGB guns on my Sony 51 inch projection TV. The color looks great and I don't seem to have the blinking indicator light bugging me any more. I will be sure to suggest you folks to anyone with these type of technical questions.

GREAT JOB!!

Have a Sony KP-65WV600, already replaced d board once, and replaced convergence ic's once also. Now as soon as I turn unit on, turns to red screen and shuts off, video that is, audio works ok, noticed...


Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)

Im seeing duble words,how can i fix it?


Hi,
There should be a convergence adjustment on this set. It will have a "cross hair" type pattern
You adjust the beams so that the cross hairs turn white. I believe Green is not adjustable intentionally. The procedure is to adjust the vertical Red line until it alligns with the Green line. Then adjust the vertical Blue line until it lines up with the Red and Green. The line should turn White.
Repeat the procedure for the horizontal lines. When you return to regular viewing mode the double
images should be greatly reduced or eliminated..
Hope I've helped you,
Best Regards,
Mark

I have a samsung 47 inch rear projection w/self focus there is a continuos blue shadow around images is there a quick fix


The blue is caused by the RGB gun alignment. Green is a fixed gun and Red and Blue are adjustable. In my Mitsubishi, the guns are motorized and can initially be adjusted (course) with the remote. There are more detailed adjustments that can be made if you purchase the service manual. I paid approx $19.00 on line 3 years ago and it is a complete manual. Unfortunetly I don't remember the site. To do a complete alignment, there are steps to take: starting with entering a code using the remote to enter the setup. To make a long story short, I had my tv aligned 3 or 4 times over 5 years under the extended warranty. After watching the tech, who was good, but under time constraints, it was clear that most anyone could do it if they could read and follow instructions.

No red in the image on the screen


The adjsutment that you turned down was the G2 voltage to the red tube which is just a temporary fix for a CRT which has a short developing in it. Try turning up the red adjustment again only slightly to see if the red CRT ( tube) will light up
if it does and then the set shuts down its most likely the red CRT which is bad . If it lights up but you get retrace lines but doesnt shut down it possible that its the CR board ( Red CRT Drive Board) which is at the very bottom of the red tube.

Red gun convergence problem


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.
