All those resistors and a pico fuse around the convergence board,must used a Ohm meter test all of those resistors torlerance and the pico fuse changes those resistors are not have the wright tolorance of it colors bands on those resistors and also the pico fuse,will fix this problems.

Sounds like your over half way there lol..
You now need to check the resistors positioned near the convergence ic's. They are your likely problem and go bad often when the ic's fail.

They are normally about 2watt and the values will vary but normally are like .10 ohms to 1 ohm.
I cant find a schematic to give you the exact values and locations but if these resistors measure off value at all you need to replace them with the exact value of the originals.

Heres a link to resistor color code guides just in case the value numbers are not printed on the resistors

Good Luck!!!

Most of my red crosses will line up how do i get all of them to line up. i can only move them so much


If red (or blue) will not line up in some part of the screen:

1. damaged resistor to one of the convergence chips

2. bad convergence chip

3. Problem in the DCU---digital convergence (memory) module.

If the crosses will not move at all in some area of the screen replace the chips and check the resistors(all are low value like 1.5 ohm etc)

Let me know if you have questions

The color is off and the figures are outlined in blue and yellow, plus the picture is cloudy looking.


Press menu on your set scroll down to where it says picture then press select. Now scroll down to convergence and press select. A white cross should appear on your screen. Your objective is to merge or converge all the crosses into the one white cross. If done right you should see only the white cross. You may see a little green and blue but don't be to picky. Make sure you read the on screen instructions on how to do this. After this you continue to the next step and you should see several white crosses across your screen. Do a convergence for each one of these crosses. Your picture should brighten up and your yellow and blue lines should go away. If it doesnt you have a bad convergence chip or some bad capacitors. If the first step doesn't fix it I would that you had a tech come and check it out.

Convergence chips replaced, tv powers on and no picture


You have to replace the chip with the same kind, or at least crossed referenced, but still exactly the same but diffrent manufacturer.

Convergence Problem


Unfortunately you will have to replace the convergence board in this unit. it has failed. this particular board regulates the alignment procedure that you are having issues with. replacing this board will fix this issue.

I have green outlines in the pictures


go into your menu there should be something called convergence in the menu a red and a blue convergence. when you select one you will get a cross in the center of your screen use the selection keys to move this so the two crosses are on top of each other. once you align both the red and blue ( the green is the base) then go to the multi point convergence if all crosses are lined up you are good if not then you will need to replace the convergence I.C. for that color or both. let me know how this turns out.

Do not open anything until you. Go to menu on your remote find convergence and press the volume button to the right go to manual and press right again. you should see a bunch of rectangles, now you should also see a set of red cross heirs press the #2 to move cross heirs up and eight to move down numbers 4 and 6 will move left and right and 5 will place the cross heirs back to the center once you have chosen the selected section to adjust line up the magenta with the other colors using the channel and volume buttons these move the lines up down left to right adjust all lines until they are white. i do not know how to switch from magenta to green or blue but this should get you started on the right track with out having to replace anything. good luck! if you figure out how to switch from maqgent to green or blue please post it so that I may adjust mine as well tahnks

Toshiba 65H81 convergence issue


Does the blue and red crosses move at all ... eather vertically or horizontally. if they move at all then it may not be the chips.. could be a resistor. if the crosses dont move then it probally the ic. these chips run about 7 to 45 dollars apeace depending on type. at our shop we charge around 125 to put in.

Convergence Problem - PT-61HX41


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, 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.

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.
