Question about Akai PTH5498 54" Rear Projection HDTV-Ready Television

1 Answer

Screen is off centered

I have had my Akai projection screen 5498 for awhile now, i have noticed recently that my screen is off center. Is there a way to center the screen back to where it should be. It is a little to high and a little to the right. I dont see anywhere on the on screen menu to do anything with the vertical or horizontal positioning of the screen. If anybody has a solution please inform me. Thank you

Every tv has a secret service menu accessed through a secret sequence of buttons on your non-secret remote.

With the power off, press this button sequence:

mute
1
8
2
power on

You should now be seeing the secret service menu.

TOUCH NOTHING IF YOU DON'T KNOW WHAT IT DOES!!!!!!!!!
Before you touch ANYTHING write down what the initial setting was. I mean it mister.
I think hitting volume down selects an option, while hitting "menu" takes you out of that option and into the area you were just in. There are lots of things to do here.

Before you do anything, go to the video options (there ought to be four of them), under one of them (second one I think) is the option to turn VM or SVM on or off (a setting of "zero" is off). For God's sake turn this off. I think it says "VM level" or something. Anything that says "VM" needs to be set to zero.

Now, to center the picture, I think you'll want the very top menu at the start of the service menu. One is horizontal something and the other is vertical something. BTW, it helps to have a test pattern for overscan when doing this. Do you own a copy of Digital Video Essentials? You should. Again, write down settings before you change them, so if you screw up you can fix it. To save your settings, keep hitting menu until you're back to the first screen, and hit mute twice. Then turn your tv off and back on. After using the service menu, my tv is always put in "dynamic" picture mode. Never, ever, ever use this mode. It will make the picture way too bright and kill your tv before its time. Use DVE or another calibration DVD to get the settings right on your tv.

BTW, you can also correct overscan in the service menu, but I wouldn't push it lower than 5%.

Do the AKAI PTH 5498 TV's have replaceable lamps like you hear so much about for other rear projection TV's? And if so, any suggetions on where to find the lamps? I am hoping this can improve the sharpness...


No your model has three CRTs (picture Tubes) cleaning the mirror may help to restore the sharpness and brightness unless you have other issues. I would try cleaning the mirror first. Dont use windex, just a soft damp cloth with water then dry
