TEAC dvb420 set top box

It is locked and i can't get it to work. I have turned it off at the power and back on again. Have checked all the connections.
Both red light and the green light are on (so it is on standby and on at the same time). Remote is not responding

    I am experiencing the same problem. Yesterday (23rd) the set top box froze (picture) but the sound was working so I turned the box off and on. Both the breen and red light were on but no picture. So I unplugged the unit and left it overnight and now today the problem is the same. No picture and red and green light on. Anyone else having the same problem or have you managed to fix it.

    Same problem, have left it switched off for days with no change when I switch it back on. Anyone have any ideas ?

    I've experienced the same problem with no picture and the red and green lights both on.



    It seems quite strange that so many of these boxes are having the same problem all around the same time!

    thats everyone for your input. I actually went and bought a new one for $79 and so far so good, plus I don't get any interference fromn turning on and off lights. Its the TEAC SBB450. Tossed the other one out.

    Same problem , red and green lights on , did seem to clear for a while but now , "nuttin", l paid $115- some 5 years ago, so l guess $20-00 per year aint to bad, but now l'll have to get the kids a new one !!!!! DOOOH !!!!!

    I'm not even going to bother opening it to investigate, although if anyone knows the fix, l'd be interested in having a go, its dead now , it cant get any worse.....

Sorry guys, have checked on other forums and unless it is still under warranty, or you are good with electronics, it is not worth fixing. Apparently it is a problem with the chip and capacitors on the board. I opened up my STB after fining this out and found heat stress marks all around the chip. Result : Its dead!

On another forum site, the electronic fis is posted, but you will have to good with electronics to fix it.

I just bought a teac HDB849 set top box and when I do the automatic channel search I only get 9 digital, GO and Gem. No other channels are found. when I manually key in 72 for 7two or any others I get...


I find that with my HDB849 I have to be very carefull with the positioning of the aerial/rabbit ears to get all the channels to (ABC, 7, 9, 10, SBS and their sub cahnnels) to recieve them at all. Also once you get all the channels it is prone to digitization or pixilation at times due to bad weather/very overcast days.

Try the Teac.com.au for a firmware upgrade as this also solved not being able to view avis & images, listen to mp3's etc.

Overall the majority of reviews say the HDB849 is to be avoided.

Once set up correctly through trial and error and an absolute shitload of patience and re-tuning it seems to operate fine. Just pray you do not get a power outage or you have to start all over again.

Last point, try the teac 1300 number in Australia (or relevent country) and harras them for info whilst trying to stay calm and nice with the unlucky "tech support" person

I have a digital set top box model teac dv-b800.this unit now has a flashing c-100 code has soon has you power same up and nothing else.Can you tell me the problem.


appears to be a known issue with your model of set top box and teac is aware of the issue, but will only repair for free if you are within your 12 month warranty period, if you are outside warranty, consider repairs as they are approx 60.00 and the fix appears to resolve the issue.

Cheers!

Teac digital set top box prompt every five seconds


I had the same problem - pretty easy fix. You'll need a usb flash drive with all other files removed. Go to following link:

http://www.teac.com.au/pages/hdb842softwareupgradever161008

Print out the instructions and make sure you have winzip installed on your computer. Instructions were pretty easy to follow and seemed to fix the problem. I haven't watched the TV for a long period of time, but it seemed to sort out the problem you described and system seemed to run better than previously eg. didn't hang - receception better.

Good luck
