You can, but it's a hard fix. I'm a repairman, and I don't even like to do this one!

My tv looks weird red and green. The people are bright red/orangish and backgrounds are green. The picture is perfect. I already reset. I believe the colors are out. I want to change myself. Can you help.


If the convergence appear to be correct, the next step is replace the fluid in one of the projection TV tubes. You will have to very carefully remove the screen and see into the mirror which picture tube is not clear. All the instructions will be found to fix this, by searching the this website....TvRepairKits.com. Have your TV model number and chassis number near by. Thanks for asking and show a few hands of support.

Tv comes on for 10 seconds then fades to a green tint then turns completely green for a few seconds than turns off


Hi,
Symptom shows tv got problem with green picture tube that need to be replaced.
Rear projection tv has 3 picture tubes, red-green-blue to make color picture.
Since its an old model so spare parts would hardly be available and local tv repair shop will help you to arrange required part, if they can.
Thanks.

SONY TV PICTURE TURN GREEN WITHOUT RETRACE


Picture goes to high green with retrace lines that shows picture tube is defective and requires replacement.
Usually in above symptom, TV goes to standby mode and standby light blinks when green raster problem occurred.
New TV is better option because picture tube of KV-34XBR960 would not be available any more.
Thanks.

TV picture is red.


Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

The picture is green


your picture tube is wearing out . there is a way around it it will work for a while .you need to lower the drive for the green . on the board on the neck of the picture tube there are three adjustments marked red , blue, green on the front of the tv turn down the color all the way down . normally you would have a black in white picture but now you have a green and white find the screw adjustment marked green and carefully turn it down untill the picture is black in white and your fixed . adjust color back up .... dont do this repair unless you are confortable working around high voltages a wrong move inside a tv can kill you , this adjusment must be made with power on so you can see the picture as your going ... so this may not be for you . use your own judgement ........Please if this answer helped , please rate this 3 or 4 stars . and keep me in the paid answer department . A 1 or 2 may knock me down into the unpaid ranks. Thanks Cactus Bob .

Toshiba 57h81 green will not focus


Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Picture turned green


It sound like a bad tube there are three tubes red green and blue.
i suspect the blue tube is bad. tubes cost 160.00 plus labor 450.total . sometimes the tubes
can be fixed or the tv tech can adjust the screen voltage on the tube.


good luck thanks jay leadingedgeelectronics.com
