Question about Hitachi 57SWX20B 57" Rear Projection Television

Red Light My picture is very green. I looked in the back of the TV and it seems the red light is not on. I can see green and blue, but no red. When I try to do "Magic Focus" the green and blue colors on the screen flash as usual. When it gets to red it just stops.

I forgot to mention that when I did the "Magic Focus" it stopped at the red and a Number 5 appeared on the screen. What does this mean?

No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

No picture coming from red lamp

Sounds like you have two differant problems. A red drive or red picture tube is bad and the conbvergence IC's are bad. To test the red drive disconnect the green picture tube socket BUT MAKE SURE THE SET IS UNPLUGGED!!Then remove the red socket and move over to the green tube. Then turn on the set. If you get the same out of the green then you have a drive problem that needs to be trouble shot for a bad componet. If you do get a picture with the red connected to the green then the red tube is shot. If you know how to read a schematic, get one and then you should have no problem troubleshooting the red drive and the convergence problem. If you dont then there is no easy or quick fix as this is a solid state set and there are no user replaceable parts inside this.,. Your going to need, for safetys sake, call in a trained tech to assist you with this repair

Hitachi 57swx20b color bad, all 3 lamps are still working, bringing tint control all the way over to the left (max red) helps a little but still to much green in picture. picture is still sharp and cl TV has never been touched until today, 12-31-12. I pulled the front inspection panel off and could see all 3 lamps lit. On the convergence screen the red and blue are aligned perfectly but no green shows up just a white, red, and blue and all are aligned, no bowing in picture at all). What can I do to repair?
