Model # 25GT522JX2, Chassis # CTC177AF3, was dead, onboard tuner was
very bad, & corrupted the EEPROM. Repaired the tuner, & put in a new EEPROM from a CTC177AF...slightly different, but ok for test! Now, on the first page of the customer menu, the SAP section is blank, & see thru. Did the "write trick" by turning the set off & installing the old EEPROM while pluged but turned off! Now the old EEPROM has more sensible info in it, but with either EEPROM, pressing the menu button a couple of times the set will shut down, or lock up the set, even make the tuner tune off frequency, it's doing all kinds of wild things. Is the Micro bad? I never saw this before. Ideas anyone? Thanks, Dani. |
