I'm new here and hoping for some help. I have a HL - S5687w that's now 9 years old. It's been a wonderful TV all these years. It powers on just fine but will shut off after about 40 minutes or so. I usually wait 10 minutes or so before turning it back on. Any sooner and it'll just shut right off. After a short rest, it appears to behave normally. I've done a bit of digging around here and it looks like it may be time for a new ballast. I've watched a few videos and it doesn't look that complicated, just time consuming.
My questions are: should I go ahead and replace both fans at the same time? And, I've seen on the Samsung parts page that there is a thermostat available...should I replace that as well? If so, where is that located?
Thanks in advance for any help!
