The colours are no longer lining up. On captions you can see the three seperate colours. The auto focus does not fix. How do you enter service mode to adjust grid lines?

U can't do any grid lines adjustments for this problems,the tv problems it is having are known as a convergence pictures problems,it is dead.The tv have any colors lines like R,G,B mis alignments,tv have any colors shadows pictures or have a 3D pictures look alike?Yes,than the tv convergence board it is dead for the tv to causes all of these convergence pictures problems.The tv convergence board must have to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost like $300-350 for parts and labors.

Three colors are "bowing"...

I would take it to a TV repair place, they will charge around $50 and let you know what the problem is with it. this is your cheapest way out, it you want to get it. If you chose to take it please give me a fixya rateing. Thanks, Farren

My Hitachi 43fdx01B went from a perfectly clear picture to one with red "ghosts" and very blurry. I my TV toast?

No,ur tv have a problems,known as a convergence problems,it dead.Very common problems on the DLP tvs design flaw.Most commom problems are R,G,B mis alignment,will not align,Colors shadows pictures,3D pictured and blurry?The tv convergence board require changing the 2 STK convergence ICS and some or all it resistors are dead,must changes to solved convergence problems.The shop will cost u $300-350 for parts and labors.

Rcs hdtv multiple images

The problem you're having is due to the failure of the convergence amplifier circuit. In that circuit are some components which amplify or control the signals to the dynamic convergence yokes, which line up the red green and blue images to superimpose them over each other to create a proper colour picture. When you get a failure in that circuit, it no longer aligns the images properly, and generally you get what appears to be badly set geometry in multiple colours. In some cases you will also get a problem with the part of the power supply that supplies the convergence amplifiers, or the digicon, which is the digital convergence control module.

This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

Hello wookie300,

This sounds like a convergence problem. The convergence amplifiers in these projection TV tend to malfunction and cause this problem. Here is a way of dealing with this if you choose to repair this problem yourself.

I posted this earlier but it applies in your case:

The problem is your Convergence Amplifiers, they are usually marked with a STK392-110. You will have to also change out the fusable links connected to the STK392-110s. Desolder the pins and unscrew the ICs and remove both of them. Then desolder the fusable liks and replace them with the new ones, then insert the new ICs and solder them in (being careful not to create solder bridges). Then you will have to perform the convergence on your TV, Try to use Auto-Convergence to do this.

The STK392-110 look like two flat 6 sides rectangular boxes with screw holes on each side and they are attached to a large metal heat sink.

I hope this helps,

3 colors on TV

It sounds like we had the same problem. Our TV is the same make and model also about 6 yrs. I went to the Mitsubishi website and was able to find a service company in my area. It turned out to be the convergence amplifier. In the end we replaced a pair of convergence amplifiers and he also soldered the pins. (in home) The cost of the repair was $375, much less than purchasing a new TV. I realize I was no help in locating the amplifiers for you but maybe if you call a service company in your area they can help you with their location inside. Hope I was of some help.

This website:

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.

because you have defective convergence correction circuit amplifier! the only thing you can do now is to replace the convergence IC.
