Color alginment is off


Your TV most likely has one of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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.

3dc9420.jpg
645fba6.jpg
0dcec37.jpg
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.

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.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Covergence out of alignment on 1/4 Vertical left side of screen


You need to manually adjust the alignment:
On remote, press Menu to get to the main menu
Then arrow down to "ADVANCED FEATURES"
Then press "enter"
Then Arrow down to "CONVERGENCE" and press "enter"
"Red Convergence" should be highlighted
Press "enter"
You now have Green, Red, and Blue overlapping crosses.
If Red is out of whack, use arrows to align
To toggle to blue (and back to red), press "VIDEO"
Then align blue cross
Once the crosses look aligned, and nice and white, press "AUDIO"
This will bring up the Advanced Convergence screen
This is a grid of the same overlapping colors
You have control over the Red and Blue
If Green is very out of whack, you'll need a repairman…
While the "target" is flashing, you can move it around the screen with the arrows
Place it over an intersection to adjust, then press "enter"
Now the "target" is steady (not flashing), and you can use the arrows move your color
When it's aligned, press "enter" again
Now "target is flashing, and you can go to the next square.
You cannot adjust every intersection.
Some areas need to be adjusted via the adjacent intersection
When you're happy with color you're working on,
Press "video" while target is flashing to change to the other color
Repeat the above (blue is much harder to see and adjust for me…)
When you're happy with the entire grid, start hitting "Menu"
Each press brings you back out one menu level, until you are out of them
Once you're used to the process, it should take no more than a minute or two.

Toshiba 57H81 Flashing Red Power Light, Blown Fused F850+F852


Solved by resoldering some solder joints!!!!!!!
********
Toshiba Model 57H81 Rear Projection TV - Purchased 11-09-2001

Problem: Toshiba 57H81 Flashing Red Power Light, No Picture/Sound, Blown Fuses F850 + F852

Symptoms January, 2009:

  • Upon turning on set I got flashing red power light and nothing else.
  • Removing plug for one minute and plugging in results in:
    • Audible click, steady red power light for 2 seconds then slow flashing red light
    • Pushing power button results in steady red for about 2 seconds then slow flashing red light, no other set activity
  • Removing power cord for several hours and plugging back in made no change
    • Audible click, steady red for about 2 seconds then slow flashing red light
  • Possible related note: Over past several months occasionally the entire screen would flicker momentarily and at other times be problem free for weeks.
  • Fuses F850 and F852 found blown

Repairs Made:
  • PD0074 DEF/CON Power Board
    • There are two main power supply capacitors in this set. They are C-809 and C-810. One their negative lead on the printed circuit board re-soldered leads and nearby contacts. I’m told that because the factory left out a printed circuit board eyelet, the connection will come loose over time. When I called Toshiba customer service they said there was a known solder joint problem causing blinking red light.
    • Replaced blown fuses F850 and F852.
      • I actually installed a fuse panel on the inside of the cabinet and routed the fuse connections here instead of ordering the special fuses and replacing them on the circuit board.
      • Had to use a 5 Amp SLO-BLOW for F850. Fast blow does not survive power up. Get the red blinking light.
      • Used a fast blow 2 Amp for F852.
  • PD0073 SIGNAL Board
    • Re-soldered Q751 + Q752 STK392-110 Convergence Amps
    • Re-soldered adjacent pads that looks suspicious

Total Cost to Repair about $10
  • Twelve hours of my time over three days to research issue, disassemble set, make repairs, add fuse panel.
  • Already owned Service Manual and Circuit diagrams from a different 2004 repair.
  • Less than ten dollars at Radio Shack for fuses and fuse panel. Already had wires, etc.
  • Some solder. Already owned de-soldering tools, etc.
  • Visited both local authorized Toshiba factory service repair facilities. One said repair would have to include replacing Q751 + Q752 STK392-110 Convergence Amps with ST392-180, and realigning set for a total of $500+ and it would be more if they had to order a power board. NO THANK YOU! Other shop said $65 for site visit and $30 to make an estimate that could be applied to repair.

Panny pt-50lc13 steady amber flashing light


Sounds like a defective lamp diever or ballast.Listen for a buzzing sound when you turn the set on. If you do not hear it then most likely you have a bad ballast or lamp driver. Worst case scenerio would be the engine itself.

Thomson DTI6300-16 digital TV recorder frozen, red light on constantly, no resposnse to any commands. I think it needs a factory reset - how do I do this?


Try Resetting the box to its factory setting:
  • Menu > Setup > Help
  • Then press the Green Button (Even though it doesn't show as an option)
  • Then press the Red button for a full reset
Warning: You will lose all data on the Hard Disk!

I did this when mine wouldn't record anything and dumped all my pre-recorded programs.
Worked a treat.

Thomson dti 6300 freeview box will not come on just shows constant red/orange light flashing all the time, tried leaving power off etc....anyone know?


What to do: if you have a solid amber light If the power light on the box will not change from solid Amber to solid Red then it is possible that a problem has occurred with the current in use software. Before attempting a fix, power the box off and on at the power socket and then wait at least 5 minutes for the solid RED lamp to appear.
If it still remains solid Amber and the box will not come out of standby to ON (Green light) then this can be corrected using the software revert procedure which is done using the box front panel buttons as follows:

1. Remove power to the unit by removing the power cable from the back of the box.

2. Wait 20 seconds and then restore the power cable while pressing the standby button repeatedly on the front panel of the box.

3. Release the standby button immediately when you see a lamp flash on the box's front display, and then immediately press the following front panel arrow buttons in this sequence:

- Menu
- OK

Note: you have to do this quickly and in sequence

4.The Orange light will flash and the STB will then reboot and should return with the previous version of software.

5. The box will now be running with the previous software version but it will automatically update with the latest version within approx 2 hours and you will be notified by message which will appear in the Message area within the Main Menu.

If you're still having problems please call 08444 159 159 and a member of the Technical Team will be happy to help.

Screen went blurry 20 minutes later no picture no sound just red flashing light on front


These sets had bad welds in the gun assemblies of the picture tubes. Now, one of the tubes has failed (shorted) and the cost would be too high to replace all three.
