Most probably the blue tube is going short, there is a screen control to readjust the screen but there is about 1.5 thounsand volts on every pin and its very dangerous.if you are not qualified technician you can not do it.

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....


Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

Screen all blue


Try looking into the blue CRT lens while its on and see if the coolant has congealed. You will be able to tell if it has bacteria growing as this can cause the blue to be unresposive and make your screen have a blue haze. The coolant will need changing if this is congealed with bacteria. This is a common problem in all projection tvs blue and green are more prone to this sympton red is not.

Red screen on 50" toshiba rear projection


red tub bad, you can adjust the red tub when you take the lower part of the front panel off and the plastic cover under the front screen
there will be 6 controls on the right hand side the three top are the brightness look for the one mark "R" and see if turning it down helps.

TV Image not bright enough

I'm not sure if my answer will help much, but it is free. My experieence with this site is that without paying for premium service, you won't get much help.
I had a similar problem with a different model Panasonic projection set.I got no answer on this site, but I did from an outside repairman.
Turn your color all the way down. If it looks black and white it is probably not a bulb problem. If you see a tint (blue, green, red) over the screen, it probably is a weak bulb.
The entire bottom front of my model was held on by velco and could be pulled off.
Behind this was a removable black panel. Behind this were adjustment screws for the three bulbs. This will probably only help temporarily if the bulbs continue to weaken, but it might buy you some time as the replacement bulbs are quite expensive. Good Luck
