Post by: P.R.Gore on September 15, 2015,08:27:16

Hi,
Sony LED TV KLV-24R402A at switch on only green pilot LED lights. After @ 1min back light turns on but no OSD & picture.Stand by via remote or panel switch is not possible. Green LED blinks when vol+ or vol- is pressed, no sound or noise from speakers.Sometime SONY appears on screen while pressing OK button otherwise panel remains blank. Looks like currupt eeprom.Sopls guide also attach its eeprom dump.
Thanks,
P R Gore.

Jordan usually attaches service manuals if they're available.

I haven't been able to find one from my sources.

Don't know where you go from here.

Hi,
Sorry for delayed reply. After lot of voltage analysis I found that SDA bus going to tuner was low:so I removed SDA SCL communication with tuner. The set started working fine but without RF.
Thanks to all of u for taking interest.
