STK4274 IS the correct part number. 3 18 pin chips mounted to the right (looking in from the back) on heat sinks. Cross reference is NTE7187 available from www.mouser.com

Usually there are 2 convergence IC's, labeled STK392-110. Each IC has 3 channes. Each color needs to be corrected 2 ways, vertically and horizontally, so 6 channels are needed. usually one IC does red, red and haf of green while the other IC does the other half of green, blue and blue. If the red colors are off, change the IC closest to the red jack. If the blue is off, change the IC closest to the blue jack. If the green is out, you have a 50/50 shot at replacing the correct IC. It is recommended to use the STK392-150 when replacing the IC's so it might not be a bad idea to go ahead and replace both with the newer numbers.

Conergence issue

The convergence output IC's need to be replaced. This is a very common problem for all projection sets as those amps are high current devices with a fairly high failure rate. The job can be done in the home. Depending on where you live the cost is around $200 to $300.

your model uses two STK392-110 Convergence ICs. Hitachi also recomends replacing the feed resistors which are two 2.2 ohm 1watt, two 1.5 ohm 1watt, one 3.3 ohm 1watt and one 1.8 ohm 1watt resistor. You can get repolacement ICs and resistors at the following link and they provide step by step installation instructions with pictures. Heres the link.

Sounds like a convergence problem. First, try using your set's user convergence mode.
