Cannot adjust convergence on the blue. Its curved upward in the middle.Also showing a second image in blue.

Yes,the tv have convergence problems again.The tv convergence board require changes parts again.

Yes! an idea that the flyback transformer is shot!

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.

Solution #1

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.

Solution #2


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.

that sounds like a typical Convergence IC problem..

this is a picture of what typical convergence ics look like

THE CONVERGENCE DRIVER CHIPS NEED REPLACED. CHECKSUPPLY SAFETY RES ARE OK AFTER REPLACEING STKs RESET CONVERGENCE. CHANCE BOTH STKs.

whats the model number and i will post the ICs you need and post a link where you can get them with free step by step instructions with pictures so you can do the repair yourself and the ICs arent exspensive. Please reply to this same post.

sounds like the convergence ICs have failed. Will the red and blue move in all 4 directions when you try to adjust the convergence? If not the convergence ICs are bad replace both of them also check the resistors that power the ICs as they may be open as well.

Check the resistors right next to the Convergence ICs often 1 or 2 of them go oen when the ICs fail.

Did you replace the stk's?

The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
