Not responding after replacing my cartidge the control panel has become unresponsive. it will not make copies or except faxes. its online and loaded with paper and a fresh properly installed cartridge. it continues to make a (double beep) noise whether i press a number button or copy button.

All buttons are on and not responding except half load isn’t lit up ? Can you help thx ?

TV in totally unresponsive in many if not all areas. Only thing they all have in common is the set's power supply. They are big culprits.

Check the board for burnt rsisitors, diodes, bulging capacitors.

Go to tools then "compatibility view". If you wish to add it to the list so that it always renders Facebook this way click compatibility view settings. Facebook is a progressive company and they have been phasing out support for older browsers. I assume you are on XP otherwise you would be up to IE9+. My suggestion would be to possibly move to Chrome, Firefox or Opera which do not have an operating system limitation.

if you have another browser you can use temporarily, like IE or Google Chrome...then go to your control panel, program uninstall and delete Firefox. Then use your alternate browser to go to mozilla.com and download a fresh copy of it. Install it and you should be fine. Sometimes browsers just need to be replaced..do this and let me know how it comes out.

I have a Miele G2830sci dish washer since brand new, used twice a week in a domestic environment. I am very dissatisfied with this dishwasher because the front control panel (touch screen, no buttons) became unresponsive after six years, outside the warranty. I had the panel replaced (part was AUD$290 and labour/callout fee $210) and the dishwasher was working properly again for another 3 years. Now the same issue is appearing again. I believe that these control panels only have a relatively short lifespan relative to the other parts of the machine. The touch pane becomes unresponsive, or erratic to respond to your touch when the panel is warm, typically towards the middle or end of the cycle when the hot wash or drying is occurring. The panel would be OK when cold. But give it enough time and even when cold, it would no longer work properly. It looks like this panel only has a short useful working life relative to the rest of the machine, based on my direct first hand experience. Not good.

Replace the print cartridge
When you notice that the print becomes light or ink low or when install new ink cartridge appears in the display, replace the print cartridge. The part number for replacement cartridges is HP 20.
1. Take out a cartridge from its packaging and carefully remove the tape covering the printhead.
Hold the cartridge by the colored top or black areas only. Do not touch the copper area.
2. Press the Access Cartridge button on the control panel.
The cartridge carrier moves to the install position.
3. Open the control panel and cartridge compartment cover (it will click and remain open).
4. Pull the cartridge toward you and remove it.
3 To load the cartridge insert the cartridge as shown below. When the cartridge is pushed to the back of the cartridge carrier, push the top of the cartridge until it clicks into place.
If the cartridge moves loosely in the carrier, it has not clicked into place. Repeat this step.
5. Close the cartridge compartment cover and control panel.
6. Press Start/Enter.
7. Press 1 for new cartridge, or 2 for the old one.
• When you put in a new cartridge, you must choose 1:New
• When you put in a used cartridge, choose 2:Used. This helps you to check the correct amount of ink you have left.
TIP: If you mix up several used cartridges, it is not possible to check the correct amount of remaining ink. Once you have put in a new cartridge, use it until it is completely exhausted.

Have you replaced the image unit lately? The toner disposal section of the cartridge fills up and then spills out causing this problem. The interior of your machine is probably caked with toner also, so when you replace cartidge, you need to clean inside machine also.

Sometimes just a static shock can do that, you need to replace the control panel pcb to fix it.

cracked keyboard from a heavy hand. Will need a tech to replace.
