I had one of those also, but it wasnt the control board that went. The drive shaft had to be replaced 3 times in 7 years. I ended up buying a Samsung which was still working (without having required any repairs) at 13 years. I only switched to a top loader just a few weeks ago, because I can more easily manage clothes in and out.
Generally, appliances have to last until they die, for me. My refrigerator was replaced because it was too small. I had bought a 221L Westinghouse at a time when I was not cooking much, nor buying much. Once I began to, I needed more space. Also, defrosting the old Westinghouse was becoming a 2 weekly job, it was no longer efficient. I love the new (4 year old so far) one, its 370L and just right for me. I hope it lasts as long as the old one which went for 15 years. TV is a "dumb" Samsung 32" LCD which I bought in 2005. The screen is still gorgeous, and I have both an AppleTV and a Fetch plugged in. I used the Fetch for FTA broadcasts, because the tuner is better than the old one. When the speakers go, I'll probably get a soundbar. I wont be replacing the TV until the screen is dead. I dont know why anyone needs 75" of TV. or even 55".
