Hi,

I am facing a weird issue.When we start the tv and setup box, the video goes off after a while. The sound is on. We tried to clean the card many times with a dry cloth and start the set up box. But it starts, stays for few seconds and the video again goes off. Only sound is heard. This is happening regularly. Sometimes, an error code 2 is displayed. Cleaning, restarting the setup box has not helped.


The other weird part is, it works fine during the day. Once at night, this issue re-occurs. What could be the reason? Something wrong with card, or setupbox? Or an issue with cables or something wrong with the tv ?

I am guessing, if something was wrong with the tv, it should have happened during the day time as well. Not sure. If
