| Bush | 2850NTX | Dead | Dry joints scan coil plug & TEA5101 fop chip & TEA5101 on crt base | 14-09-04 |
| Bush | 2850NTX | No pic with burning smell | burn up on red wire of scan coil plug - wired direct to pcb | 14-09-04 |
| Bush | 2850NTX Schneider TV4 | Bent verticals and pulsating width (Scene Dependent) | Replace CC808 4N7 SMD primary side of PSU you will probably find that
the pcb in this area has taken some heat. | 14-09-04 |
| Bush | 2850NTX TV4 | Line collapse | Can be dry joints scan coil plug but C419 330nF 400v scan coupling cap burnt & o/c in this case | 14-09-04 |
| Bush | 2850NTX TV8 | Dead apart from led flicker at sw on | C203 47µ 250v - checked ok out of cct | 14-09-04 |
| Bush | 2850NTX-A | Dead aft brief micro activity | Micro reqs sync pulse at pin 26 within 1 sec from line to function. This was missing due to T301 BC547B in line stage leaky | 14-09-04 |
