Good day folks. I've got this Samsung TV with a seemingly trivial yet slightly annoying issue: the buttons on the side don't respond AT ALL, not ever erratically like it usually happens when buttons on TVs go bad. Interestingly, I thought the TV was dead when I first got it, because it didn't come with a remote, so I naturally tried the buttons first, which of course got me nowhere. Then just out of curiosity, I grabbed a Sammy remote and the thing fired up perfectly.
Initially I thought the microswitches were busted, so I replaced one of them just to check but it didn't change anything. Looking at the service manual on page 122 we have the FUNCTION block (see below), but the only thing to check there would be the A5V voltage which appears to be OK (slightly lower than I'd like it, at only 4.8v from what I recall, but considering the remote works, I assume the power section for the buttons is running fine. Doubt it's a software issue, like something becoming corrupt, though I'm not eliminating that theory entirely just yet. Has anyone ever dealt with unresponsive side keys on Sammies before ? If so, what could be the issue, besides the microswitches ? Cheers.
