Hitachi Model # 53fdx01ba v1b002594 has a red shadow on picture

I have a hitachi Model # 53fdx01ba v1b002594 that has a red shadow appears on objects on the tv. Is there a way to fix this on my own? I have had experience pulling apart smaller tv's and fixing boards before, but this is my first time messing with a projection type tv.

If you mean that one of the colors has suddenly drooped toward the center, creating a curve along the side where the colors no longer line up, it means that one of your convergence IC's has burned out and needs to be replaced. You should not play with the convergence settings when this happens because when the IC is replaced, the settings will be all out and have to be reset. It is a good idea to replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's or realigned convergence circuits then allow a qualified tech to handle it for you.

Either the pins on the convergence ICs need to be resoldered or the ICs need to be replaced. These are large black ICs attached to a heat sink and should be marked STKxxx. Resolder first. If that does not resolve it, replace the ICs.

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!

Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!
