Title: Samsung le40m86bdx eeprom clicking
Post by: kingchristo on April 07, 2011,17:37:47

Hi i have the common fault of the tv clicking. I opened it up and couldnt find any broken capacitors but i replaced them all just incase there was one that had gone that i couldnt see. The tv still clicks and doesnt come on. I read that you need to reset the eeprom chip but have no idea whitch one it is or how to do it any pictures would be great or a manual thanks hope someone can help me

The eprom is situated under the card reader slot and does not have to be programmed as the data is loaded from the micro

you can use a 26c64,thats just fine,when the eeprom gets corrupted ,if wont re-programme,as it gets damaged,a quick way to fire set up is short out pin5 and 6 on eeprom ,clk/data this will re-set and at least tell you whats going on
