I have an 890 with blank screen - Went through all tblshooting
with logitech and they said the LCD was dead. It is out of
warranty and they cannot tell me how much to repair.
Looking for eyeball cost to compare with buying a replacement.

steve201, have you opened a case with logitech for repair?
I recently have had my 890 volume up button go faulty (I need to press hard to get it to work).
I opened a case with Logitech and although it was out of warranty by more than 8 months, the warranty department decided to send me a new replacemet 890 complete with extender etc.
It may be worth your while to go ahead and open a case and see what they can do for you.
Also one recomendation when buying anything like this that may go faulty:
use a credit card that has an extended warranty benefit. There are lots of cards out there that double the manufaturer's warranty up to one year, just for putting the full purchase price on their card.
BTW Logitech rocks!

I've decided to take a chance and send it in for repair, I saw one post somewhere that said they charged $50 and returned a new remote.

I am interesetd to see your result, I have a 890 that has a blank screen. harmony told me a min, of $75 up to $195.

I've posted this elsewhere, but FWIW, my 880's "play" button stopped working about 10 months out of warranty...too much DVR use, I guess...wrote to Logitech complaining about a $200 remote wearing out after less than 2 years, sent it to them for a repair estimate...$50 bucks...I paid it and now they said they decided to give me a new one instead or repairing the old...

Wow,

Did not know that many were having problems with blank LCD screens. It started about 2 months ago. typically at night. The LCD screen would go blank, although the buttons worked. My fix was to remove the battery and replace. It worked but only temperarely.

I emailed logictech and did not hear from them in the 4-6 days they indicated. I sent them off an email yesterday looking for a response. When I got home I had a brand new 890 pro. Kinda a waste as they sent me the whole package and I only needed a new remote. As of yet they have not asked for the old one back.
