Saw a few postings lately that make reference to a P50 service menu that allows you to view the display timer and other goodies.


Any tips on how one can access this menu?

The numbers are interesting. Present time said 95717 min. That's

1595 hours! I've had the plasma 2 months. However, if you divide

by 10, it's closer to an accurate number, ~20 hours/week. However,

I believe I watch more than 20 hours per week, but maybe not. I'll

have to pay closer attention. The 1595 also matched the total

in Mode A. But the RGB and Video numbers were 165h and 175h.


So, I'm a tad confused.


Also, in the Adjustments menu, what happens when you select

"Defaults"? I was afraid to press it! :)

Edit: I also noticed a baud rate for the serial port. I wonder if

if it's for logging/diagnostics or will it also take commands for

"professional" adjustments?

I placed a copy of the Fujitsu RS-232 command manual on my server, if anyone is interested... at the moment, it's at:

http://www.2150.com/files/rs232_commands_P50XHA10.pdf


I may relocate it once I have enough pieces of material to make some reference pages, so if you're reading this some time later than I've posted it, and you can't download it, send me a note asking for where I've put it. :)

Anyone know what the V Orbiter "On/Off" does?

It opens up the option in the regular menu to apply the screen orbiter to all video modes. Wish I had know that sooner before I burnt in the number of Rupees from Zelda in the lower right corner.

Has anybody pressed the "Default" selection in the last service menu?

I'm still chicken.. :)

Pressing default in the last menu will zero out your hours and erase all your custom presets, so don't do it. Also keep in mind that when you are in the timer menu, the larger number simply refers to how long the unit has been "plugged in" and the smaller number refers to how long the unit has been on in the various modes.

larry,


I did it just after I accessed the service mode for the first time. It resets everything on the P50 to the default settings, including all memory presets. It also wipes out the hours.

Ouch!


beware of anyone offering to sell a used P50 with 'low hours' on the clock!


you should not be able to zero out the hour meter that easily

Phew. I almost did it because I thought the little icon next to"Default"

meant it would open a sub-menu. Thanks for the info.

I also noticed that on non-digital inputs, there is an option for AGC on or off.


I assume this is the Automatic Gain Control.


Anyone tried turning this off or on?

Thanks for the "Default" warning, I almost used it.


The "Fan0" setting sets the fan speed. I wonder if the speed increase is automatic as the unit starts overheating?

Do you have a space heater? :)

John, I'm fairly sure the fan speed is controlled by internal temperature

inside the housing. The fans are louder and pushing more air

when the unit is "hot" vs initial power up state after sitting overnight.


I was just thinking that I hope these fans are of higher quality than

some PC power supply or case fans I've had the dubious pleasure

of owning. Hearing the fans "sing their song" would definitely be unwelcome.

Although, the fans should be covered by the 3 year warranty.

No I don't have a space heater; but the summers get over 100° and I could leave open the windows/doors and the AirCo off. Now my wife and 2 Huskies would be real upset.

I would most likely be forced to the DOG HOUSE!!! Worst yet not able to use the P50.

Just hope they are the ball bearing type!
