search on the internet under "how to clean grape juice from a wool carpet" (assuming the carpet is wool not silk), you'll find lots of methods. For example,

I am not recommending these or any other methods.

Spill a small amount of warm water and let it run down to wash out the pickle juice. Of course do this without the power cord connected. Let the tv dry long enough to be sure the water has evaporated before re applying power. Just might work.

HI,
To solve this problem you have to open your tv and using a hair dryer het the are of the control panel this will evaporate the moisture at the touch panle switches . After that reassemble the same and check. The problem will be cured.

To disable receipt printing:

• Press the Rcpt/PO key in the OP X/Z position. This key toggles the receipt printing status ON andOFF.
• To check the receipt printing status, turn the mode switch to the OP X/Z position or press the CL key in the REG mode.
  
• When the function is in the OFF mode, the receipt off indicator “_” illuminates.

To issue a receipt when receipt ON/OFF function is set to OFF:
If your customer wants a receipt after you finalized a transaction with the receipt ON/OFF function in the OFF
mode, press the RCPT/PO key. This will produce a receipt. If more than 50 items were entered, the receipt will be
issued in a summary receipt format. Your register can also print a copy receipt when the receipt ON/OFF
function is in the “ON” status.

The following is the process to stop customer receipt printing. It will also describe how to print an individual receipt on demand. Best of luck and thank you for using Fixya! Kindly return to rate this solution.

Receipt ON/OFF function

You can disable receipt printing in the REG mode to save paper using the receipt ON/OFF function. To disable
receipt printing, press the Rkey in the OP X/Z position. This key toggles the receipt printing status ON and
OFF.
To check the receipt printing status, turn the mode switch to the OP X/Z position or press the lkey in the REG
mode. When the function is in the OFF mode, the receipt off indicator “_” illuminates.
The register will print reports regardless of the receipt state, so the paper roll must be installed.

not knowing what the model is I suspect the machine suffered a power surge or got a spill

I believe this might help, not exactly familiar with this exact model but here it goes.
Receipt ON/OFF function
When you use the printer to issue receipts, you can disable receipt printing in the REG mode to save paper
using the receipt ON/OFF function. To disable receipt printing, press the Rkey in the OP X/Z position. This
key toggles the receipt printing status ON and OFF.
The register will print reports regardless of the receipt state, so the paper roll must be installed.
To issue a receipt when receipt ON/OFF function is set to OFF:
If your customer wants a receipt after you finalized a transaction with the receipt ON/OFF function being OFF
status, press the Rkey. This will produce a receipt. However, if more than 30 items were entered, the
receipt will be issued in a summary receipt.
Copy receipt
You can print a copy receipt by pressing the Rkey when the receipt ON/OFF function is in the “ON” status.
To realize this function, you must enable the function. Please refer to page 62 (Job code 63).

To give it a good cleaning, you will need to remove the keyboard and clean anywhere you can see juice or feel stickiness. You can buy the expensive computer cleaners, but I suggest 50/50 rubbing alcohol and Q-tips. Remove the battery and C-mos battery to make sure there is absolutely no power to the machine what so ever. After cleaning inside, you will want to give it a good 24 hours to dry, ensure that there is no moisture before applying power. If the juice reached the bottom of the machine, you may need to remove the screen, split the cases, and take the motherboard out, in order to clean the bottom side of the board. If you leave juice anywhere on the board it will gum up, and the acids in the juice will corrode and detierate the circuitry on the board causing a motherboard failure. Now the keyboard, in order to thoroughly clean the keyboard, I suggest that you spray a good amount of the rubbing alcohol in the keyboard, shake it or blow it out with air, then take paper towels and daub up the rest. Repeat this two or three times, then let it dry approx 24 hours. Sometimes the keyboard won't recover after a spill and will need replaced. If it works properly, then, after using the keyboard for a while, you will notice if any of the keys are sticking. Take the sticky key or keys off and clean them individually. I know it's alot of work, but it'll teach you not to keep open drinks around your laptop. It did me, I've ruined one machine, two keyboards, and thoroughly cleaned a third very expensive machine of mine to keep it working, but I finally learned to drink from a sippy around my laptops.
