Hey all!! First time posting here and first off, THANK YOU so much for all your postings regarding power problems on various models.
I have a KV-34XBR910 that started having this problem about 6 weeks ago. When I go to turn on the set, I get the degauss noise, but the TV doesn't kick in. At first I only had to hit the power button on the remote a couple of times and the TV would come on. Now I'm up to about 20 to 30 times for the TV to come on. I'm afraid to turn it off after reading a few posts where members weren't able to get their sets back on.
Also, the last time this happened after pressing the power button on the remote, the TV did blink three times before not staring, not sure if that helps.
Thanks to so many folks here I think I've discovered a possible solution which is to replace the MCZ3001D ICs off the D Board.
>>I have a couple of quick questions before I get started.<<
1. This is my first time soldering an IC. I have a motherboard from a dead PC that I can practice on. My question is can you use any soldering iron? I really don't want to spend a bundle just in case this doesn't solve the problem. I've seen soldering kits for around $15.00.
2. Is the MCZ3001DB a suitable replacement for the MCZ3001D? When I check the schematics of the D board the part is listed as MCZ3001D.
Thanks for your help!

Awesome! Thanks for the response. The chips should arrive in the mail Tuesday or Wednesday. I was feeling a little trepidation about doing the repair myself until I called a local "Sony Platinum" repair facility. They wanted $300.00. The upside was that this was a flat rate which included a technician coming to my place to do the repair. Still, I'm confident that I can tackle this myself, in great measure thanks to your detailed overview of your own experience.

Make sure that everything has been reconnected to the board and visually inspect your work for solder bridges or other possible errors.
