Projection TV Problem

I have a 50-inch rear projection TV. When it is turned on, it works good for 10 or 15 minutes (sometimes for 25 minutes), then forms images with separated color. Any suggestions will be greatly appreciated.

(Many posts suggest convergence-circuit problem. If so, why does it work fine for several minutes when turned on, and then only go bad?)

Thanks, Slinteriors. In replacing the ICs, I am concerned about the residual high-voltages. Are there any locations I should avoid coming into contact with? Are these easily identified?

Also, can I find step-by-step instructions on the IC replacement process? Thanks again.

The convergence ICs are nearing the end of their operating lifespan. You will need to replace both ICs . Let me know if you need more information.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.

Veon tv manual


The eject button on the remote appears as an upward-pointing arrow with an underline - see below image. The eject button on the TV has a similar symbol.

However, I suspect that in your case, you might not be having a Remote.

This link says that your TV doesn't come with a Remote and DVD cannot be ejected without the remote :

I have a 39 inch element tv i cant program the cable channels


Typically you can access the menu, select "tuner" or something similar, make sure you're selected either on CATV or ANT (or similar), then do a channel scan. Should be pretty straightforward. Oh, and make sure you actually HAVE cable. If it's digital cable, you may need an external converter box for it to work.
