Blown fuse found PSU on this one was shorted. Changed bridge rectifier. Powers up ok but can't get keyboard to take instructions. Disconnected the keyboard, Using remote doesn't accept commands. Could be main board issue. Anyone had similar issues?

Replaced also IC-U2 (FSD-200) and 3 electrolitic capacitors in the same circuit and optocoupler

Hi Jordan. I replaced Fsd200 at the same time as the bridge. Could you enlighten though. If the optocoupler or capacitors were faulty the set wouldn't power up would it? Picture comes on but just doesn't respond to keyboard or remote. I disconnected the keyboard because the led's keep flashing.
It responds turning on and off by remote but can't seem to get it to go down the page of channel menu to start auto search for channels.

Hi Cornboats,

Notice a lot of really cheap main and DVB boards on the Flea if it's Logik LCXW-37HDI - Chris.

I'm not sure wether its the main board or the dvb board thats the trouble.

Chris is right! These boards are only about 10 quid each!
