Red lamp issue

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?

What's your problem?Pioneer PRO-530HD 53 in. Rear Projection Television flashing red standby light

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.

I have a Sony KP-53S35 53 inch Rear Projection TV connected to a Directv Receiver. The TV does turn on, but the screen goes blank and VIDEO 1 is displayed. It will stay on, but will continue to do this. ...

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.

Red green and blue lines

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!

Lamp Light Red - No Screen Image

It could be the a problem with the lamp ballist circuit, or just a bad lamp socket, or simply a bad lamp. The only way to tell is to call out a servicer as that would be alot less expensive then to get a new lamp and then that not be the problem. These problems can be a little hair pulling at times, thats why i have no hair left!! LOL Good Luck
