Question about Toshiba TZ55V61 55" Rear Projection Television

Tosiba TZ55V61 Convergence IC 150?s vs 110?s

I am working on a friends set that needs the convergence IC’s replaced. I am wondering if it is advisable to use STK392-150’s instead of the factory STK392-110’s. I see in the spec sheet that they are rated for higher wattage, but wondering if anything will really be gained. Also, if the 150’s are used will any other components need to be changed out such as a resistor?

Thanks,

STK392-150 can be replacement for 110's no other resister values need to be changed, however be sure bad resisters are replaced and check all the resisters (6) have been taken out of circuit and checked. also check for solder cracks and cold solder joints.

Changing convergence I.C.s in Toshiba 61HX70


the 392-110 used in this set can be replaced with either 392-110 or 392-150----The 150 is a higher current rated IC-------I do a lot of these sets---I would not go to the 160 IC as you may run into problems----also---the 110 should last 3-5 years and the 150 longer---make sure when you change them to check all the protection resistors in front of them and do not forget to put heat sink grease on the new IC's

If this answers your question give me a vote here----I have repaired hundreds of sets with convergence problems---its ok to go up a step or two on the quality of the IC, just don't get carried away---keep it simple

Poor colour balance


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.

This website:

http://www.techlore.com/forum/thread/18547/Mitsubishi-convergence-IC-s-used-in-the-differant-models/

says your model uses the STK393-110 convergence chip. Another site I looked at said that was a 6 channel amplifier so I'm guessing you only need one to repair your TV.

If you do some google searches on "stk392-110 convergence problem" you'll find some good sites that discuss how to repair the tv. The STK392-110 is a convergence amplifier that is used any many other sets.

Good luck.

Most likely the convergence output IC has shorted out and has overloaded the convergence power supply, which has stopped working. The computer senses that the convergence power supply is not running and shuts the set down. The convergence IC should be replaced, the power supply restored and the convergence circuits realigned by someone experienced in Mitsubishi projection sets. When I do a housecall for a set like that I charge $150, but shops in your area will vary so ask around.
