First thing to check are the convergence chips, as these are the most likely point of failure. They are typically STK392-XXX part numbers, and are readily available. the second possibility (far less likely) is a fault in the digital convergence module, specifically the circuit controlling red. if the convergence chip(s) are bad, it is also likely that the fusible resistor between the chip output and the convergence yoke will be open, make sure to replace that with a suitable replacement.

This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Won't Close


Remove power from the opener. Then, pull the red release rope and manually lift open the door. It should move with little effort. Next, pull the door halfway down and let go. The door should stay where you left it. If it fails either test, the door lift springs need replacement or adjustment. If it works ok, follow the proceedure in the owners manual for adjusting the up and down limit sensors, and the emergency reverse adjustment.

Your TV most likely has one of two 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.

Ok, so I Replaced stk-392-110 (2) and......


Check the resistors in the red convergence circuit right next to the Ics you will need to lift one side of the resistor out of circuit to acurately check them but usually one or two resistors will be opened when the ICs go out
