this unit came in for no power symtom. found vertical diode and resister open . replaced vertical ic and diode and resister, now it turns on but have no picture or sound. checked votages on tuner and i can't seem to find a 12v supply anywhere. does this set have a 12v supply to tuner. does anyone have a print on this chassis or info on tuning circuit.after futher checking the channel up and channel down button turn the tv on and off, that's all they do. sounds to me like an epprom problem. does anyone have a number for the eeprom or any suggestions i don't see many mags around here. al marquardt ampm@xxxxxxx ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html ------------------------------------------ ***NEW*** Tips Added Instantly!!!*** Submit Repair Tips here: http://www.tech-assist.org/secure/tip/
