Magic Focus does not work.

I got convergence problem and have a double images. After being failed Magic Focus, I tried to use manual adjust by interrupting the magic focus. However, when I finished the manual convergence (actually not help), I lost my magic focus function. Every time when I press the Magic Focus button, I got a grid screen, not the working Magic Focus. Does anyone know how to get the magic focus back?

Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
with upgrade Stk394-160E Hitachi part # CZ 01341,change both
for reliability.....check B+ feed resistors for over-heating....T.

There are 2 primary things that can cause this problem - a bad TEMP sensor that is sensing too much heat, OR, a lamp that is going bad, which sometimes causes excessive heat before it dies. Either way, the set will shut itself off, and you can turn it back on in about 5 min or so, and it will work OK....for another period of time before it shuts off again.

You need a good TV Tech with the Sony Service Codes for your set, to come out & check your set. The Service Codes will tell him the exact problem you are having, and how many hours your set has been running. Most of the time a new bulb solves this problem, (if youe set is at least 3 years old).

Good Day,

Sounds like the TV's convergence circuit has failed:
*Call an Authorized Service Center and them give you an estimate cost of the repair, or
*Repair it your self; get KIT 10 locally or B&D Enterprises

Good luck, big IRISH.

HITACHI ultrascan hd tv....

color is suddenly oversaturated, and the picture is "dark" , been trying to adjust with the remote... help!

I recently moved and after it had been off the moving truck and working for a few days, I noticed the picture has shadowing and a double image.

Almost as if the RGB coloring is out of alignment. Does this relate to the convergence or focus problems I have read about.

Hitachi TV, has red ghost lines outlining image on screen! Help!

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.

f0900cb.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.

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.

color convergence on Hitachi Projector TV

Color convergence will not align

Answer

  • Most Helpful of 2 Answers

The color has gone crazy on you because your convergence IC's have gone bad.
These IC's operate at a very high temp, and usually only last 4-5 years. 
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-120's or something close...regardless - you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack.
Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go.
If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!
Hope that helps!

Manual Convergence adjustment on Hitachi 43UWX10B

I have Hitachi 43UWX10B and the color is out of sync. I have replaced the convergence chips with the updated STK-392-150 version. I checked the resistors and they all seem OK, no burn marks and resistance is as it should be. The problem is that the picture is still distorted. I press the "Magic" button and picture is still the same as before. How do I manually adjust the convergence on this TV? Magic button goes thru the sequence but the picture is still like 3D. Please help.

I would guess you missed a open resistor--there are only about 12 of them--how did you check them?

This set (43uwx10b) has a tiny blue micro switch on the front of the chassis---if you engage it from the front the set will go into the DECAM or convergence mode--let me know the CLU number on your original remote and I will scan and paste instructions---98% of the time if the set is wacked out and will not adjust one of the resistors is gone---ONE OF THE CHIPS GETS THEM.
