Member: 5713 Status: Offline Thanks Meter: 0 | its just above the P.A on the left has NN044 marking on it . Silver component. Check for broken solderings under a microscope . Another reason is oxidisation or poor connection of pin 1 on Cobba. If pads are oxidised Cobba wil have to be removed and the pad cleaned up .Try reflow Cobba with hot air first though. I've found the 6210's & 3310's dont respond to reflow as the 8210's & 3210's do they are harder to fix. |
