The residual function as well as the r squared function are gone! They aren't even in the catalog and when I reset it they don't come back! What can I do to get them back?

Check it with setting up after an other code to your device. If you wish to get more codes to your Insiginia set, check this link.

Your keypad seems to be worn. You can order a new one by model off the internet and aren't that hard to replace. Just be careful.

Does the front drive shaft turn? Maybe the hubs aren't locking in. If the hubs don't lock, then even if the transfercase is functioning you still won't turn the front tires. Hope this helps, Shaun

Ink levels are usually calculated several ways. It typically does an average page count for the cartridges, and starts notifying you when you're running out of pages. There is also a microchip on the cartridge itself that notifies of the level. Sometimes there are even additional ways, such as cartridge weight, etc. If you're trying to reset the levels to get more life out of your cartridge, don't worry about it. It'll keep printing until the ink is gone. When you see the quality start to decline (IE colors aren't as vibrant, pages aren't as dark) that means it's time to start looking into more ink.

WD-40 will get it off very quickly.

This error generally means that your cartridge chips cannot be recognized. The primary causes are: Covering of the LED at the back of the chip (by ink?). Incorrect chip positioning on the cartridge.The LED on one or more of the cartridges has been damaged if removed from original cartridge.The Chips have been mixed up, if removed and replaced, the wrong Chip has gone on the wrong color. And lastly Ink is covering the cartridge chip or a sensitive area of the cartridge and preventing the LED light sensor from functioning. ( my problem)

Hello,
Turn the satistical plots OFF
Press [2nd][Y=] (STATPLOT). Select or enter 4: to execute the command [PlotsOff] [ENTER]

Clear the lists (statistical lists)
Press [2nd][0] (Catalog]. Press [PGRM] C. The cursor jumps to the first command in catalog that starts with C (The greek letters in names do not matter). Scroll down a bit to reach the command [ClrAllLists]. Select it and press [ENTER].

Try your graphs again.
If you still have problems, just reset the RAM:
Press [2nd][+] (MEM). Press 7 to select [Reset] then [1:All Ram][2:Reset]. Press [Clear] to erase the Ram Cleard message.

Now you should be able to draw the graphs.

Hope it helps.
Thanks for using FixYa.

To turn on the residuals, you must turn diagnostics on.

Press 2nd then zero. You are now in an alphabetical catalog list. Go to the d's in the list highlight "diagnostic on" and press enter. This will take you back to the home screen. You must press enter and get the word "done" on the home screen.

If you are trying to get the residuals in a list, you must calculate a regression first. Then when you press 2nd stat, resid should be in that menu.

From a physics perspective, there may be a residual charge on some of the digital bits that could be read with sensitive instruments and manually reconstructed after hours or days of manipulation, but as a practical matter, your data is probably gone. Unless your data is worth tens of thousands of dollars or more, it's probably not economical to recover it, if it's even possible.

don´t you activate the text function of your tv check in the menu if that are active.
