Мои познания в ремонте данного вида техники: Любитель (делаю только для себя)
Наличие схемы: AGC-1220RF-A
Dear Forum members!
Sorry, my english is poor (my russian also poor, I read this forum with online translator).
I have an Renault ARA-1230RF car radio, but inside is there is an AGC-1220RF-A maindboard.
The problem is,
- the system random overheating and turning off (protection),
- no illumination light for the buttons.
My firend is an electic professional, and he was testing the radio:
- we know somewhere short circuit is in the 3.3V line,
- we have ordered and installed a new LV5692 chip (because this chip turns on/off the illumination lights), unfortunatley no changes, the old chip was good,
- we have reading in this forum, that we have to test the RAM - tested, works fine.
My friend said, the mainboard has multiple layers, and he can't test more, because we don't have a wiring diagram.
My question is, can You help me with a AGC-1220RF-A (Daewoo manufactured the mainboard) wiring diagram?
Best regards,
Bela from Hungary
