Cannot start TV and scan has no signal (1 Viewer)

[Richard G Hole]

Hi

MediaPortal had been working well for my Duel tuner Hauppauge card for a couple of years.

However, today I ran of space on drive C while MediaPortal was recording. I moved and deleted files to free up some space on C drive. However, I cannot start the TV. A message comes up saying “unknown error occurred” I have Windows XP and tried to paste the address C:\Program Files\MySQL\MySQL Server 5.1\bin into the black box as a command as https://forum.team-mediaportal.com/threads/tv-suddenly-doesnt-start-anymore.93197/ may be indicating. After clicking start and then run I typed “cmd” and pasted
C:\Program Files\MySQL\MySQL Server 5.1\bin
into the window but the command was not recognized.

I tried another method which https://forum.team-mediaportal.com/threads/tv-suddenly-doesnt-start-anymore.93197/ may be indicating. In the search window after clicking “start” and “run” I also tried entering C:\Program Files\MySQL\MySQL Server 5.1\bin instead cmd and the folder came up. I am not sure where to enter the code. Are there step by step instructions for this possibly with screen shots of the windows where to enter it?

I also tried completely uninstalling MediaPortal and reinstalling it again. However, now during the scan for channels there is “no signal”
Oddly before doing the scan the TV channels I scanned in before were listed in the TV EPG grabber. This is strange as I completely uninstalled the software and cleaned everything and reinstalled it again so I would not expect to see these listed. Perhaps it did not uninstall properly. I tried a complete uninstall and reinstall before for a similar problem and it solved the problem. However, it does not work this time.

Your help would be appreciated
Regards Richard.

Hello

Someone suggested to paste all of the below text into the command window before hitting “enter” and not just the first section for a start.

CD C:\Program Files\MySQL\MySQL Server 5.1\bin
mysqlcheck mptvdb --auto-repair -e -u root –p

I did that and it ran. However, it did not fix the problem. It appears as if MediaPortal is not completely uninstalling as channels are still listed in the EPG grabber when I reinstall even before I scan. Should I delete the entire MySQL in the program folder in Windows Explorer. If not what could I do or delete?

Regards Richard.

After doing a fair bit of searching I tried the final suggestion at https://forum.team-mediaportal.com/threads/mediaportal-does-not-uninstall-completely.83979/ that suggested to use Revo Uninstaller. This enabled deleting the registry keys that were not uninstalled by the normal process in Windows. The corrupted version was not being totally uninstalled without the help of Revo Uninstaller. I also read that MediaPortal has some parts that are not uninstalled during a normal Windows uninstall. I am not sure if this will be a problem in future versions?

MediaPortal is working again now after being reinstalled.

Regards Richard.

Hallo,
first thing you should do if you have a problem running MediaPortal:
->Collect logs and post them.
I think you do not have to reinstall every time, if a problem occured.
