| Philips | L6.2 | Only standby LED on, no high tension | Check +150, this has to be around 150V. 145V is too low and then there is no 5V for the microprocessor. Check R3509 and D6501 Replace R3509 by 47k 1 Watt version (4822 053 10473) D6501 is BZX79B5V6 (4822 130 34173) | ||
| Philips | L6.2 | Only horizontal white stripe on screen. No vertical deflection. | Check T7904, T7905 and R3908 on deflection module. | ||
| Philips | L6.2 | Only horizontal line, no vertical deflection. | 1) check on 110 degr. module if 25V is present on C2916. If not present, probably D6907 is in short circuit and/or R3928 open. Change D6907 into BYV27-400 codenumber 4822 130 70055. R3928, 1 Ohm, codenr. 4822 052 11108. 2) check if R3908 does n | ||
| Philips | L6.2 | Only horizontal bar. | Bent top of R3908 away from spring of T7904. | ||

| Philips | L6.2 | No TXT. No wide screen. All options are "N". | Check soldering of pin 6 (SCL signal) on connector 065 audio module. Resolder all the pins on this connector. | ||
| Philips | L6.2 | No Teletext if set is switched on from standby position | Check and replace if necessary the components C2604, C2606 and R3633. REMARKS : The tolerances of above components can be out of range. IRIS CODE : 231X | ||
| Philips | L6.2 | No picture. Storing presets not possible. Very slow control with R.C. | Check MSP3400 (IC 7221 on audio module) | ||
| Philips | L6.2 | No more deflection or E/W failure in 110 degrees module | Change D6906 to BY278-20; service code number 4822 130 11369. REMARKS : Only for 110 degrees module | ||
| Philips | L6.2 | No more deflection because 25 Volt missing on 110 degrees module. | Change on 110 degrees module D6907 to BYV27-400; service codenumber 4822 130 70055. IRIS code 1 3 1 6. REMARKS : teletext version only ! | ||
| Philips | L6.2 | No E/W or width control | C2915 390n | ||
| Philips | L6.2 | Loss of picture carrier or frequency drift | Change R3420 (see diagram A1) from 12k to 18K (service code 4822 116 52251) |
