Question about Akai PT4298HD Rear Projection Television

1 Answer

Double Vision This tv is only about 4 or 5 years old, always worked fine until now. Its kinda like a double vision with seeing everything in somewhat normal color and then seeing it again in green... Plus it looks like the screen is falling like curved, falling down starting in the middle. Any advice?

    I have the same problem, it just started this week out of the blue. We bought the tv in September 2004, (we bought it in anticipation of the Rex Sox World Series, that's how I remember) and it has a lot of green, the color is off and it's like there are double screens. In October of 2007, we paid $335.00 for another problem. It is so disappointing and I would never buy another Akai.

We recently moved the tv and now when we turn it on it has double vision. It kinda looks like a 3d movie. What could be the issue? Is it worth fixing?


Hi,
If tv picture was fine before moved then check dry/ cold solder joints/ connections on convergence output ICs and nearby circuit area.
Local tv repairman will resolder loose/ dry solder connections to solve double vision picture problem.
TV worth fixing if picture is good.
Thanks.

Double vision..


Adjust the convergence in the menu. If it will not adjust then solder connections on convergence ics or ics themselves need replaced.

This is a convergence problem and is either bad connections at the convergence ICs or defective ICs. If you can solder, you can repair this yourself. Let me know if you wish to repair this and I can provide you with additional details.
