What are symptoms if MONITOR or TV’s EEPROM data is corrupted or damaged?

• No high voltage (no display). • Horizontal or vertical frequencies run. • Cannot save (store) current setting. • Certain control functions like sound, brightness and contrast control does not functioning. • On Screen Display (OSD) does not function or OSD have a corrupted display. • High voltage shut down (EEPROM set horizontal frequency way too low or twice line frequency perhaps leading to failure of horizontal output transistor (HOT)).

What is an EEPROM programmer or copier?

EEPROM seldom fail, they just lose or have their memory (data) corrupted may be due to high voltage and static discharge from a monitor. Once reprogrammed they are as good as new. As mentioned earlier, new EEPROMs are blank and need information or data to be loaded in order for it to functions. The job of copying data into an EEPROM is done by a programmer or a copier. Programmers comes in all shapes and sizes. You can copy these devices for repair replacement only. You cannot copy them for resale without a letter of approved from vendor who produced them. There is quite a number of companies selling EEPROM programmer: - Typical EEPROM part no: - 24C02, 24C04, 24C08 etc 24C325, 24C645AT17C65, AT17C128 etc 93C06, 93C46, 93C56, 93C66 etc 25010, 25020, 25040 etc

Based on my past experiences, I spent at least two hours each day to read electronic servicing books and magazines. I have learned tips and information, which helped me to be more efficient and enhanced my knowledge about electronic servicing. I have benefited tremendously from reading these technical books and magazines. I am now a successful technician with a rapidly growing business, which specializes in repairing monitors and printers. I believe that you, too can achieve what your heart desires!
