Question: I keep getting a "no data base" message. How do I fix this?
Document: Movement of any kind is fatal to receiving the digital signals. Those that complain simply don't get it.The main purpose I purchased these were for emergency/storm/power outage reasons. Here are a couple of work arounds to getting a good signal.Using the supplied antennae or another larger antennae run the set up search for channels. Get the channels you desire locked into the data base. You may have to go outside. Now that the data base is set you can navigate to your preferred channel.
I bought this for my husband for Christmas. He absolutely loved the picture and the few stations he got were fine.One week later he got a no database message that he could barely see. Getting hold of customer service was an absolute waste as previously stated by another customer. If you got this product and it has maintained function - great. If you are considering this, I suggest that you might want to look to a brand you are familiar with and that will be easy to return, if need be.
Great picture. Getting reception sometimes more difficult than expected, but think I will like it. Anxious to see if it will work in the car while driving.
I live in a larger city, but a converter box would not pick-up more than 2 stations. This picks up 15! Thinking of getting one for my bathroom!
I didn't get this from Amazon. Picked mine up from an auction for $2. What I wanted was a little TV to keep on my computer desk. And for that purpose it has been excellent. I only tested out the tv for picking up local channels over the air. And the included antenna was able to pick up a couple of channels.
I use this as a monitor for my wireless video camera system installed in my business. The picture is clear and bright. The base station plugged right in and worked with no setup. I chose this unit for the price - because the previous unit I bought recently went from $40 to $80. This is a great unit and a great price.
I bought this today, 12-18-11,  on sale at CVS for $29.99. As soon as I plugged it in, searched the channels, it was ready to go. I bought it to have around for when we have storms or no electric. It is charging now, but with the adapter in, the picture is beautiful. There is a pull out lever on the back and it seems to keep the TV balanced.
The 2-position fold-out stand is flimsy so I'm careful with it. There is a standard tripod screw-hole mount in the base, too. The only improvements I could think of would be to include a protective soft case and to throw in a pair of earphones. If it stops working properly I'll add it to this review, but so far I would recommend it with no hesitation.
Super picture, bright and clear. It pulled in all the local channels. I bought this to monitor the local stations during tornado season here in Oklahoma. I put Velcro on the back of the unit and stuck it to the wall of our storm shelter. Add in the August DTA240 High Gain antenna outside the storm shelter and you have an emergency TV that will keep you informed.
You will also need a tripod to stand it on (like the small ones for digital cameras) as it does not have a base that stands up easily. You also have to have a lot of patience to locate a signal as moving even slightly makes a big difference. It's a bit clumsy with the external antenna attached. I think we were used to the mobility of the old analog type products and this technology is a bit quirky. So if you're the impatient type, this might not be for you.
Answer: Check antena connection, move device to different location, and check auto channel at each location until get it.
