Question about Hitachi 43FWX20B 43" Rear Projection Television
The red lines on the grid will not line up. They are curved, the ones on the top curve up and the ones on the bottom curve down. We have replace the stk's. What could be the problem?
red lines across screen
EXACTLY it Big Irish!! Different levels + different bleed level. Tube means this set is shot to snot to me unless rejuv works. Can you please post HOW to rejuv a tube? For that matter - what is rejuv? :D

Good Day y'all;
First of all if the lights are on, that's good, the red light,LED's, indicates that there is power to the power regulator IC. The green lights, LED's, indicate that the DC voltages are present for those particular circuits. ALL GOOD! If off bad!
If after replacing the IC's with the 150's and still have color shift and all resistors are within 2% tolerance and adjustments were made properly. The digital convergence board may be defective.
If the picture is bleeding that normally is a gassy CRT, picture tube, and the bleeding changes with the brightness levels. You may try to rejuv but that may short life the tube.
Good Luck, get back if you want more details, Big Irish.

SOURCE: red will not line up
Had the same problem a couple of years ago, it is a defect in the TV. Contact Hitachi it's a convergence issue they will do everything to tell you it's wear but that is not true. I made a big deal about it and finally after contacting many people and doing much research on the problem Hitachi agreed to paid for the part which costs $360.00 Cdn. However, they did not pay labour (only $65.00). Hope this helps.
