| Bush | 2866NTX | Sound absent | 5v supply to NICAM board low at 3v. Q581 BC537 faulty tho checked ok - used BC639 in lieu | 14-09-04 |
| Bush | 2866NTX | St/by only | Replace the micro type CTV352/V1.4 (Amstrad pt no AM045101070211 ) | 14-09-04 |
| Bush | 2866NTX | Tripping | Lop tr s/c BUH515D - used S2055 also e-w mod diode - caused by dry joints hi volts tuning cap under pcb (under sticky pad) | 14-09-04 |
| Bush | 2866NTX SM2 | Txt missing | Short pin 20 of IC301 the micro to earth then switch on. Service menu should appear
Service- Telra V2.0; OP byte 1 OX OB; OP byte2 OX BO Init EEPROM.
Use P+/P- tp select the line to adjust and V+/V- to adjust.Bytes 1 and two must be as shown above.
To initialise the EEprom select the line and press V+/V- Correct handset reqd. | 14-09-04 |

| Bush | 2866NTX/SM2 | Line tearing when heated | C597 (22nF 400V) completely open circuit. | 14-09-04 |
| Bush | 2866NTX/SM2 | To access tuning mode | press and hold [MENU] button for at least 5 sec.
Then press and hold the white button for at least 5 sec to auto tune all the channels. Then use the green button to re-arrange the stored channels. | 14-09-04 |
| Bush | 2866NTX/SM2 | Won't store or loses chan store | This was cured by replacing memory 24C08 | 14-09-04 |

| Bush | 2867NTX | Install menu & chan 1 posn locked | Reqs password - if the password is forgotten then use 734. This will allow you to unlock the channels. To open the install menu however you must unlock "all" the locked channels. If you find that you cannot enter the tuning menu one or more of the 100 channels is locked, so search through them all and make sure they are all unlocked. | 14-09-04 |
| Bush | 2867NTX | Locking codes faulty | EEPROM faulty | 14-09-04 |
| Bush | 2867NTX | no sound | check TDA1521A o/p chip & R811 4R7 also replace C365/366 1000µ. C374 470nf leaky in this case | 14-09-04 |
