Question about Akai PT4298HD Rear Projection Television

1 Answer

Green color gun shot

The green color module (for lack of a techy word)seems to have gone out. I have a red arc at the top and bottom of the pic, and any writing on the screen is arched to match, with ghosting, straight red writing. This is the second set of RGB color modules. Is this something an average DIY'er can fix?Is it worth paying someone to fix?

    Thanks, found a guy to come out and replace them for $195.00 cash, but he discovered the blue color is completely shot, no blue at all. He wouldn't give me a price to replace one, as he feels you need to replace all 3, and at that point I'd be better off buying a new TV. At least he was upfront with me on the cost, but is he right? Can I get just the blue lamp replaced? Is it worth it?

Have gone from a good picture to green and blue picture.what happened?


Hi:
If you are connecting the unit by componet cables (RED,GREEN<BLUE) check the cables first to make sure all are connected. If you find they are ok then your red tube may not be lighting up. If you are using a cable box try connectioning the set direct to the cable outlet on your wall. You could also be missing red drive signal to the CRT, in which case service is needed.

When the display is dark i get red and green arcs on the screen


Hi,

Color arching is an easy fix. You need a screw driver and some patience removing the front panel. You will be looking for a box with 3 screws on it. This is the color gun. THe scews are Red, Green and Blue color only, however, they usually don't indicate the color on them. Turn the screw (Slighlty) till the arching is no longer there. You have to do this with the tv on.. LOL

My E771 monitor colors suddenly shifted with


Possibilities:
1. video-card gone bad;
2. video-cable gone bad;
3. video-cable not tightly-connected to CRT;
4. video-cable not tightly-connected to video-card;
5. "red" gun inside CRT gone bad.

Disconnect the video-cable from the computer, and try again to adjust the "red". If red-free, then it's time to responsibly recycle the CRT.

Reconnect & wiggle the video-cable, to see if that induces any "red" onto the CRT.

Connect the CRT to the VGA-output port on a notebook computer, to see if that video-card generates "red" as one of the primary colours.

Give the CRT a strong "whack" on the side, to see if "red" makes an appearance.

Green picture only


The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Toshiba 32A41 TV -- color problem


Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements. It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron
