Re: Samsung UN40EH5300 on/off


Hi Jeff,
I have the exact model of your TV: Samsung UN40EH5300FXZA version: TH01 and the exact same problem. My TV is less than two years old and upon turning it on, it starts to power off and on periodically for the first 30 minutes or so. It also doesn't recognize my WiFi although my tablet does. I opened it up and the caps look fine although reportedly that doesn't mean they aren't bad. After considerable internet research, it seems it could be the power board or the main board. Like you, I really don't want to buy a part that doesn't...
