This sounds like a crt. What is the make and model number? It could be in the convergence circuit of the tv. To trouble shoot this, you need to have a qualified technician look at it.

Replace a projection bulb on a RCA D52W23?


Hi,
I have this tv.
pull it out and start undoing the screws towards the bottom half of the tv around the back, get the speaker grille off and then in there is your access cover for your bulbs. theres three of them red blue green. the bulb assemblies and circuit boards are integrated 3 bulbs -three separate assemblies. you will probably have to turn the tv back on when its disassembled to see which bulb went.

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.

I have a toshiba 65hm167 no red color on the screen


Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

Turns green and shuts off


I had an electrician come over. He pulled out the bulb that was dead (for me it was the color that was flashing before it would turn off) and now I have a blue and green TV with no red. He said that the only way to fix it is to replace the red lamp with a new one.
