Yeah, I know it's there.
But, I couldn't open it up.
I couldn't see which screws were holding.
I pulled out(?) almost all screws, then I was gonna break the cooling unit.

I really need help where I should screw, with pix...
The black and white drawing(I don't know what to call) of C800G, grrhhh..

I try again today anyway.
Thank you for cheering me up.
You gave me a hope to hold on to for one more day.

Is it the tube used on C800G?
I knew tubes in C800G are made in Russia, and I wanted to know which brands SONY adapted.
(I heard SONY doesn't produce tubes by themselves. They must buy tubes from somewhere, and they are using those on C800G.)

I just changed the tube in mine, it was due. I got the exact tubes that were recommended in this thread, with the same length as the sony ones. Look wise, they are identical. I got 10 for 18 bucks including shipping, really good price, and they sound great. I applied the thermal grease in there, with no problems at all, and added some Foil duct tape on top of the tube to seal everything. Now it's heating up and ready to go. No buzzing, no nothing. If someone like me can do it, anyone can. I'm really not manually inclined and it took 45 minutes max!

I want to thank everyone who posted here, it helped so much!
