Videocon Industries — problematic stb

My videocon d2h set top box has it's own set of problems

1. Many a times the information screen remains stuck onscreen and then it does not go away. This is annoyance because i can not view the full picture. The only solution is to switch off and switch on the stb. Sometimes i even need to factory reset the stb but still the problem comes back again in a few hours.

2. Even though i have not touched the stb the smart card loses its contact with the stb and i get a warning to insert the smart card and never remove it in future.

The box appears to be faulty and d2h is just interested to replace it with hd stb and do nothing about it.
