DVB Tuner

[nings]

Hello,

I have a question about a DVB-C tuner who suddenly stop receive channels.
Working very well but now I can't found any channels when I scan all frequencies.
It's not a problem with signal or cable because an another tuner work perfectly.

Do you know what components I should check and if it's repairable ?
I found really few documentations about that issue and all people change the tuner without try to repair

Philips SAA7146
Demodulator : TDA10023
Tuner : CU1216L


Thank you for your help

follow the tracks between the input connector and the chips.
there is usually a transistor that can get spiked by static or just fail.
