Sony KDF 42WE655 Red lamp flashes 10 times what error code is this?


The ten blinks indicate that you do not have the 5 volt output from your DTL module on either board one or board two.

I replaced the lamp and now my left speaker makes a sound as if its not conected correctly, then the tv turns off and the red light blinks seven (7) times, pauses and blinks 7 times again.


Hi,

7blinks is an error code for "Audio Error". This kind of symptoms is an indication of fault either on the KD board AKA Audio board or the G1 board (supply line for audio board).
You have to isolate the fault between the two boards by measuring the supply line for the audio board. If the supply voltage is intact this is an indication that you need to replaced the KD board. If there's no output voltage from G1 board feeding the KD board, then you have to replaced the G1 board.

Hope I helped you.
Have a nice day!
Thanks for using fixya.

My sony kdf-42we655 has 7 flashing red blinks. please help.


Audio Protect (7 Flash): When DC voltage is detected at the speaker or
woofer outputs, IC3604/pin128 (TV-micro) goes low and IC3604 turns off
the main power (AC relay turns OFF).
Troubleshooting Tips:
1) Main cause of defective will be located on the KD-board
2) Confi rm KD-board is securely seated on the G2-board
3) Replace KD-board
