After a storm my box keeps asking for first time installation but when I do it it says " no channels found check antenna" the antenna is fine as tele works perfect. Is there a way to reset the box

Check and replace its tuner. It is faulty. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

yes it does seem to be a tuner problem , I also wonder what happens when you use the auto channel finder and tuner usually found in the set up section of the menu ? As well as was your TV working before and receiving input via the antennae but has now stopped working in this regard ? I also noted that attaching an analog to digital converter box worked fine , so your TV is capable of receiving a signal via that method , dose the converter box use your antennae input jack or a video jack to send the converted signal into your TV ? if it is using your antennae jack then it may not be a tuner problem .

try connecting your ps3 to aonther tv via hdmi, if it does not work then the hdmi port of your ps3 has a problem.

Do you have an antenna hooked up? You'll need one hooked to your converter box because the digital signal is so much more difficult to tune in to. This may help:

If you live closer than 15 miles, rabbit ears
If you live closer than 20 miles, omnidirectional
If you live closer than 50 miles, midrange outdoor (oldschool arial w/ rotator)
Further than 80 miles, you'll need a long range with rotator, perhaps even an amplifier to go with it. Print off what your results were on antenna web and bring it to a RadioShack or a local antenna store and they should be able to point you to the right antenna for your particular location.

try googling how to build an antenna with coat hangers. not pretty but cheap!

Welcome to the world of digital broadcasting. Chances are the antenna isn't positioned quite right for the station that's giving you trouble. It's not a TV issue or problem with the converter since other channels are fine, so it comes down to signal strength. Most of the time it's okay, but sometimes when band conditions change it gets weak enough that the converter box can't tune it. You might try shifting the antenna slightly while noting signal strength on the different channels. You'll likely find a few degrees change may give you a reliable signal on the problem channel without noticeable reduction in the others.

You need a stronger antenna. Many of the VHF channels moved over to UHF thus if your current antenna doesn't pick up UHF, you will not pick up those channels.

I just had a similar problem with this box - For the first month or two, I got the local NBC affiliate (KING-5 in Seattle) just fine on 5.1, then, after fiddling with my antenna setup, I lost it completely - NOTHING I could do would get it back. I tried a bunch of stuff - Multiple types of antenna, adding an antenna amp box, a handful of "homebrew" antennas - Nada. Yet all my other channels came in fine (although a couple were right on the edge - This box seems to need a "17" or higher on the signal strength - Some of my channels were reading in the 15-18 range, and suffering the "blockies" and sound dropout)

After hitting TVfool.com, found out that the KING digital signal is actually broadcasting on channel 48. Punched in 48.1, and there it was, clear as a bell, using nothing but a "wick" antenna (Basically, strip 4-1/4 inches of the outer braid off one end of a piece of co-ax cable, leaving the center wire alone, then plug the other end into the box) getting me a 23 signal strength. But a second or two later, the box is displaying "5.1" - Weirdness...

Reconnected a near top-of-the-line Winegard Yagi/Log-periodic antenna - VERY directional, and has some gain all by itself - and the signal jumped above 50.

Still couldn't "channel-up/channel-down" or punch in "5.1" to tune it, though - Channel 5.x was a "dead zone" as far as the box was concerned.

Re-did the "autoscan", and now, it's back to normal - I can channel-up/channel-down to it at 5.1, or I can punch it in as 5.1, or I can punch it in as 48.1, and it's all good.

So, try re-doing the auto-scan. Worked for me...

Hello Faznmc,

I have found that with an ordinary antenna connected to the converter box it can receive nearly all channels, however I have run into cases where I had to use an amplified TV antenna to pick up signals. I have started telling folks that when they install their converter boxes to try to use the plain old rabbit ears antenna, but if that does not work, use an amplified antenna, and that usually does the trick.

I hope this helps
Thank you,

yes out dated tele
