Have you ever dropped it? If so, there may be something wrong inside it and you may have to open it up and see. I am not much of a technition on the inside of the calculators, but check to see if any thing is busted or if there are any "loose wires". If not I suggest that you ask a professional.

Why can't I get any video when I connect the S-video output from ny laptop to the S-video input jack on my TV?


Not only must you connect the two physically with the S-video cable, but also divert the laptop screen display to the TV or replicate the laptop screen display on the TV screen.

On Toshiba laptops, you use the Fn-F5 key combination to play with the display. Look at the screen capture from my Toshiba laptop. While pressing simultaneously on the Fn and F5 keys, use the right arrow to cycle through the various schemes. For your case use the 4th or 5th scheme.

Neptune TL locked lid light stays lit


foxste
I will give you a few things to try that are non technical and let’s see if the Control Board will let you in Service Mode. If so we will try lock and unlock the washer in Service Mode.
The Service Manual for reference. Sears Parts Direct for reference.
Let enter Service Mode;
Enter the Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”

Board Output Test
While in Service Mode, pressing the Delicates key will begin the Board Output Test. This test turns on a
specified output after a key press. (Pressing the Delicates key again cancels the test.) All outputs
will be turned off after five (5) minutes.

Now Press the Colors / Jeans key this should lock the Left and Right Lid Locks….. did it?

If the lid locked now press the Extra Rinse Key and this should Unlock the Left and Right Lid Locks….. did it?


Let me know and we will go from there. I’m trying to get a feel for what Control Board functionality you have……Rich

My JVC TH-G30 gives me a locked message when I try to open the load tray what should I do?


hello Setting the disc ejection lock
You can lock the disc tray to prevent the disc form
being ejected.
When the main unit is turned off, hold down the STOP

If you attempt to open the disc tray by pressing
OPEN/CLOSE key, the disc tray does not open and
“LOCKED” appears in the display window.
To cancel the disc ejection lock, hold down the STOP

Washer keeps getting dc code, doesn't matter how big the load is. Have unplugged the machine and moved clothes around but it still keeps doing it.


Most of the time this is a clutch malfunction. If you feel you can DIY after reading this post we will try to help.

I always recommend folks to check the Tub Displacement Sensor its fairly easy to do thru the washer lid.

Some handy links the Service Manual for reference. Sears Parts Direct for reference.

TDS check from the SM slightly modified;

It is possible the Tub Displacement Sensor may have failed try this check which is in the Troubleshooting guide stored in your washer console or refer to the SM. This done thru the lid.

a. Enter Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”

b. Press the Super Wash key display reads “in”…something like that.

c. Press Delicates the Display will show “UC” (Unbalance Closed).

d. Push tub to the back right corner of the machine the display should change to “UO” (Unbalance open). Release tub and the display will show “UC” (Unbalance Closed).

e. Press Hand Wash.

f. Pull tub to the front left corner while pushing the tub down the display should change to “UO” (Unbalance open). Release tub and the display will show “UC” (Unbalance Closed).

If you get these results your TDS sensor should be just fine.


You can pump out the excess Tub water with this process from the Service Manual;


I would go to page 16 of the SM lower right hand part of page, Board Output Test and turn on the drain pump in service mode to pump out the tub.


Enter Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”

Pressing the Delicates key will lock the lid. Now press the Presoak key the drain pump will turn on. Turn off the drain pump with twith the off button or hit the Presoak key.

Poat back if you have questions or concerns....Rich aka dh1200s

All keys in the 4th column enter a 6; press 3 displays 6


Does pressing the '6' key do nothing? If so, it sounds like the '6' key is stuck. Try repeatedly tapping on the '6' key to get it un-stuck.If that doesn't work, it's probably time to get a new calculator.

Scanner won't make copies


Maybe this will hellp others with this, if it's an output issue vs. scnaning, or those w/related Copy problem. I could not Copy without the message about Incorrect Paper Size. I finally found this link which solved that problem AND one of the paper feeding in poorly and at an angle which preceded the error msg by a week, resulted in angled prints on the page.

You may have an issue with your "spot sensor" and it needs to be calibrated.

Instructions:

1. Press * and # at the same time, and then release both keys.
The display reads "Enter Special Key Combo".
2. Press 3, 2, and then 9, releasing each key before pressing the next.
The display window should read "Service: R0622M" with a revision number.
3. Press the right arrow button once.
The display should read "System Configuration".
4. Press Enter or OK.
5. You will be prompted to enter serial number. Do not enter any information
on the unit.
Press the right arrow button until "media sense calibration" appears in the
display.
6. Load Paper into the unit and then press Enter or OK.
7. Media Sense Calibration process will take place.

Hello, Kindly ineed your'Support ihave IBM Thinkpad Laptop keyboard function give output error i type u come output 4 wrong key fuction kindly ineed your;s help Thanks for your support with best regards,...


When the RH side of the keboard types numbers instead of letters then the Num Lock (number lock) key has been pressed.
Press the Num Lock Key again to return to letters again, usually this is usually done by pressing the Shift key plus the ScrLk (Scroll lock) key, this key will be also marked NumLk, and there will be a LED light that will indicate when the number lock is on.
