Is this a Hitachi set? If so then check the model number and be sure it's right.

The color on the tv is messed up the green and red i tried auto and manual magic focus but cannot move the green line on manual magic focus please help

Most likely this set has bad convergence ic's and some open resistors. This is a common problem for projection tv's. Check:
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
I hope this helps. Thanks for using fixya.

Resistors " RK42 3.3ohms
RK46 1.8ohms RK50 2.7ohms RK54 1.5ohms RK58 3.9ohms RK62 2.2ohms After you replace all of them then enter convergence by pulling OFF bottom front panel there on front of convergence board is a small blue button press it and a convergence pattern will come up now aline each color red then blue.

I need the resistor values for RK42, RK46, RK50, RK54, RK58, RK62 when using stk392-120 chips in Hitachi 53UWX10BA.

If it is 53uwx10B:

RK42 2.2 OHM 1 WATT
RK46 1.5 OHM 1 WATT
RK50 2.2 OHM 1 WATT
RK54 1.5 OHM 1 WATT
RK58 2.7 OHM 1 WATT
RK62 1.8 OHM 1 WATT

Double check the numbers on the STK chips as most of these sets use STK-392-110 OR 392-150 CHIPS-----ONLY A FEW OTHER MODELS(MOST 43 INCH USE THE 120 CHIP.)

I do this here for free so if this helps you take just a minute and give me a vote here.

If you have any questions or need help reply to this posting here--I am here to help people.

Everything looks like a 3-D movie!

Replace convergence IC's IK04 = STK392-150 and IK05 = STK392-110. Also check resistors RK42,RK46,RK50,RK54,RK58,RK62 for burnt/discolored.
