The Alphabet, Tks for advice.

I already unplugged everythings and ready to send it back for checking and repair.
Scott, what do you say on firmware down load? Otherwise I send it out tomorrow. Tks.

TheAlphabet,
How frequent you had experienced the problem of need to turn off the main power at the back of your unit or plugged from the wall outlet? Did it happen lately to your 990?

I had my 990 returned with the latest firmware installed after repaired. Scott advised me that they did not find anything wrong, but still changed a few capacitors at power section.

I took Scott's advice of plugging the 990 to the wall outlet directly.

For past 2 weeks, I turned it on 4 times. 2 times I had to switch off the power main switch at the back of the unit. First instance I left and waited overnight before I tried again. 2nd instance, I waited a few minutes before pushed the main switch back on and it turned on with the remote. This 50% sucessfully switching my 990 on with the remote on the last 4 tries confused and fustrated me a bit. I am wondering what I should try next.
