...a very SHORT while. I needed a small TV that I could carry with me on my job as an AV, video and CATV services owner. I do a lot of work with school districts, designing and installing their CATV systems. A small TV comes in handy when I need to look at the output of a combiner or a wall drop. When this unit arrived, I opened it up and set it up as I'd need to use it. I did an off-air scan just to see how it picked up the local HD signals. Not bad, as it found most of them, even with the supplied telescoping antenna. So, I tucked it away and waited until I needed to take it to work with me. The first time that I needed to look at a signal in a school's headend, it worked OK. I turned it off, then a few minutes later, I needed to use it again. It came on for about 2 seconds, then went blank. No power LED, no nothing. I checked the AC adapter's output with a voltmeter...it was dead. I found another 12 volt supply that I had, cut the cord from the Haier's supply and quickly spliced it into the new supply's cable, checking to make sure that the polarity at the plug was correct. I slid the power switch to "on", expecting to see the power LED come on, but...nothing. I checked my new power supply...it was OK. Tried again...nothing. I got about 3 minutes of service out of my TV, and now it's RIP. I can't return it because the original power supply has been tossed, and I've dismantled the TV to see if I could repair it. The power switch is junk, but that's not the problem. I did get the power LED to come up a couple of times, but it was only briefly.
This little TV is just what I need, so I'll probably buy another one and hope that the 2nd time is better. If that one shoots craps, it's going back.Get more detail about Haier HLT71 7-Inch Handheld LCD TV.
