I have a Pioneer 53 in. rear projection TV which will cut on with green light show image of channel and image will be covered all in red the shutoff by the protection circuit with red light staying on. I have pulled the red wire out of the splitter for the red lamp and cut on TV and TV works fine except no red color. I have also put the blue lamp (red wire) in where the red lamp was and everything works fine except no red in picture.
Have isolated it to the red lamp and its components, wondering what next to test or replace?
Wondering how to identify what is the Horizontal Output Transistor?

The color which you see has problem i think you might be seeing white slanting lines also with this. it mainly due to

3 green tr. defective

a 240 ac voltage appliance will run happily on 220 volts but ther is obviously a fault as the green spark was possibly a fuse blowing ie main fuse as power is not reaching the tv
This and a few other models like it have one real common issue:
they develop from age and heat bad solder connections all over the power board (rather large board).
My experience with them is the fix usually is remove rear cover and follow power cord to power board (a lot of plugs to mark) and remove that board----then solder every single connection on the board which by the way has some special fuses on it.
Hi, Press any channel button on tv remote to switch its input source as TV to watch tv channels. As you said, screen shows Video-1 display that means tv is set on input-1 that need to be changed, press channel button on remote or tv front to shift it on tv channels mode. Let me know if you have additional question. Thanks.
sounds like the high voltage transformer arc or one of the picture tubes arc causing the convergance ic to go bad you can try to replace the IC heres a site to help: http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm
Most projection TVs have an option to refocus. For example, my Sony rear projection TV has a button on the front for focusing the lamps. Try finding this button or option in the menus with your remote.
Projection TVs actually use three lamps, one red, one green and one blue. These need to line up exactly in order to form a good picture, and when they come out of focus, you see the edges which sometimes has the effect of a 3D image when you aren't wearing 3D glasses.
Hope this helps!
