Question about Toshiba 50H72 50" Rear Projection Television

1 Answer

I think the color tube is shot

I have half a screen top part is black and bottom part is picture with yellow red and blue line across the middle section of the tv. Seems like the tube is shot. I have looked online for this part and if I am correct it is about $200,00 plus a service call. I have only had this tv for 5 years... I thought I would have had it longer than this before repair... Anything I can do without calling in repair???

Red screen, horizontal lines, 2'' black vertical bars both sides


it looks to me that you are not a technician becouse you are measuring at the wrong places risking a hazard shock if you have a little experience get the service manual and check your power supply and the h v capacitors near the horizontal output if not please take it to your service center

On a white picture my screen has a yellow color to it and at times mill have a blue blur on the bottom left corner of the screen. also i get blue dots in the middle on the screen.


Hello: Seems like you have a picture tube problem. The yellow color is from a weak green crt. I suggest replacing the Red and Green Crt's in this model. They are nortoriuos for Failure especially the Red. The cost for these tube vary from 110.00ea to 150.00each. I don't know if you want to spend that type of money on this set, as i Know this peticular set has an expectional picture quailty, my experience with replacing sony picture tubes, is to replace all three tubes, as the new ones will show brighter. So replacing the red and green crt's and not the blue is not recommened. But thats up to you, you might not notice the color difference yourself. You also have the option of sending the Crt's for refurbished ones or having the originals rebuilt by a company in Calif, called VDC, Video display Corp. They sell and refurbish sony CRTs. This route is much cheaper, the only problem is having the crt's taken out and sent for repair. The other option is to think about purchasing a new set. As this repair price could reach into hundreds of dollars, Around $600 to $700 for parts and Labor..

Color issues are harder to solve without seeing the problem. It sound like the red amplifier on the crt board is bad. Is there any red in the picture at all? If not, that will be you problem

Colors off. blue and yellow not lined up


try to set the convergance if you cant you can adjust the color tubes from inside the tv but have to be very careful to do this. There is actually only 3 colors in the tv red, blue green so I would say your blue and green need lined up

Blue tint and lines on screen.


Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
