My T2200 is a cause of quite a bit of frustration. The unit goes through short periods of stuttering, no audio, playing a few secs then pausing, rinse and repeat, then displays the Poor Signal message. This can go on for 5~20 mins. It happens pretty much on a daily basis to varying degrees, however, the unit is fine for the vast majority of the time in use. I have a relatively new aerial, with booster and it works perfectly when connected directly to the freeview tv, no signal reception issue at all, period.
I'm wondering why the signal issue occurs for short periods and at random times? If a fault within the aerial, booster or cabling I would've expected prolonged periods of poor signal reception. Could it be hardware related with the component receiving the signal? The unit is kept up to date re firmware.
Be interested to know if anyone else has encountered a similar issue or any suggestions?
This sounds very similar to my experience. A UHF Band Pass filter helped a bit (you can get these on the DishTV website), but ultimately I ended up replacing the box. The new box still has the odd hiccup but not for more than a few seconds as opposed to the prolonged periods of issues that I was having before. So, try the filter, also try the splitter as suggested and if neither works, take it back for a replacement. Don't try to put up with it.
