TELETEXT ERROR MESSAGE CODE c208-U2-L909 MEANS NO TELETEXT. WHAT CAN I DO?

Found your answer:
Thread Sharp AR M236 Service code U2 40

There is no Error code U2-40 for an AR-160. Did you mean an error code U2-04?

U2 04 mean eefrom read write error serial communication error

I was getting this on my new amstrad sky+ HD box on BBC txt. This happened using the txt button on the remote. Using the red button gets round the problem and now the txt button seems to work as well.

CLEAR THE ERROR

Enter SIM


# - * - C - * - 16 - START

This means that the cartridge's sensor is miscommunicating with the copier memory thus the code U2 -40. You should clean the inner sensor connector and the toner sensor of the spilled toner by low blower. Perform this code ;# , interrupt , C, Interrupt keys in that order and press 16 then Print key and the code will be cleared.

Hello sir; This error code it can be reset folloe the instruction;
1, press "clear", "interupt", " 0 ", "interupt"
2, enter 16 then press start.

U2 RAM error
U2-00 EPROM error
U2-01 Counter error
U2-01 Memory back-up battery dead
U2-04 EPROM error
U2-11 Main counter error
U2-12 EPROM error

As you can see there are many U2 error codes. Needless to say, find your code and the replace the bad part. The battery is on the main board. The EPROM is on the main board.
If you find your code, replace the part and error still remains -- replace main board.

To find out the sub code for the U2 error hold down the Start key. Below is a list of the errors:
U2-04 EEPROM serial communication error
U2-11 Counter check sum error
U2-12 Adjustment value check sum error (EEPROM)
U2-40 CRUM communication error

To clear the U2-40 error try pulling out the toner cartridge and firmly reinstalling it. If that doesn't work you must install a new toner cartridge. There is a CRUM chip on the cartridge that keeps up with how many impressions have been made with that cardridge. You cannot "refill" these cartridges without replacing the CRUM. This problem occurs frequently with remanufactured cartridges.

To clear other U2 errors you must enter simulation mode.
Perform the following procedure to enter the simulation mode.
Clear key - Interrupt key - "0" key - Interrupt key - 16 - Start key - Start key. The unit should reset.

There is a long list here for the U2 code so if you let me know I will tell you what it means..
Again what is the Last part of the Code?
If it is U2-40 code, it is a Crum Chip, Take the toner out clean the end of the toner cartridge, there is a chip, a small plastic connection piece with bronze/silver wire on it.
Or replace the toner cartridge.
You will also need to clear the code with simulation 16.
Turning the machine off might work but, not usually.
