You have a bad tuner or there is a capacitor bad in the color burst circuit.

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!

This model uses two convergence IC's----if 3 D one or both are bad.


Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.

Both chips and any bad protection resistors around them need to be replaced and the set adjusted.

If you are able to do the repair yourself total parts cost will be under 30 dollars.

Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.

When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.

After some years the grease dries out from the heat and one of the chips goes instantly.

You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--

If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.

If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.

If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.

IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know

I can tell you what you will need aside from the parts and how to proceed with the fix---

If all this helped rate this solution---I do this here for free.

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.

Regards, SD TECH

You have a bad light engine (optical block). This is the most expensive part of the TV. Do a search with the model number on Google or Ebay and even type the words "light engine" in your search. You can then find the price of the part. You can find a service manual by typing in the model number followed by "service manual". This will show disassembly instructions.

Broken screens on 53'' Hitachi rear-projection TV


I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.
