My M90a recently made an update to the capacitors and transistors for the drivers. I used KSA1381 and KSC3503 and UPW capacitors.The M90a sounds good now, but the light still doesn't turn on when I press the power button. I replaced the two bulbs (one covered with red and one covered with yellow) with other originals. No lights come on yet. I ask for your help. Thank you
