| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KVFX29 FX | White horizontal line no vertical deflection | Check / replace R548, R549 | ||
| Magnavox | RP2781 C101 27X105-00AA | No vertical deflection | If resistor R445 1ohm has gone open circuit this may cause IC550 LA783x to also fail. Replaced both IC550 and R445 | ||
| Nokia | FX | Left part of picture missing after fitting vertical modification kit | Make sure you have fitted the extra capacitor between pins 8 and 9, instead of 10 and 9. Fitting incorrectly will destroy the sandcastle pulse and make the picture appear strange | ||
| Philips | 20PV164-05 | vertical frame collapse | Change vertical output drive IC and nearby electrolytic capacitor | ||
| Sony | KV-A2923 | Set starts, horizontal and vertical deflection work, HT ok, crt heaters ok, but no sound or picture | I turned the G2 voltage up and noticed a white screen with flyback lines, frame ok. I detected two badly soldered double diode rectifiers in the secondary part of the power supply ! I checked all other joints, and everything was ok !! success | ||
| Sharp | DV7045SN | No vertical deflection | R615 open 0.13 ohm 1/2W. Also resoldered many bad solder joints | ||
| Tandberg / Seleco / Sinudyne | 3TS645 PC170 | No vertical scan, just one bright line in the middle | Suspect R235 18kohm, in some cases the TDA3654 may also have failed | ||
| Sony | KV-M1400 BE2A | Insuficient vertical deflection. Line rolling on top of picture | Replace ceramic capacitor C524 | ||
| Sony | KV1412 | vertical line at the left of the picture | Replace L506 on A board, replacement part number 1-407-366-00 | ||
| Bush | WS6671 11AK19 | Very low width and bowed verticals,no ew correction. R626 o/c | C630 390nF, 300v faulty, located next to scan socket. This fault can also be caused by R629 2R7 fusable o/c. In my set C630 was dry-jointed but not faulty. Check generally for dry joints in the E/W and PSU areas. Note that R629 is a safety component | ||
| Toshiba | 28W23B 11AK37 | Picture displaced vertically, picture too high or low | This problem was cured by entering the service mode menu then 4,7,2,5, then pressing the green fastext button to access geometry settings, selecting VP1 vertical position and adjusting as necessary | ||
| Sony | KV-M2131U BE1 | Intermittent loss of syncronisation, both horizontal and vertical | The surface mounted power transistor on the teletext module requires resoldering. As there is evidence of scorching on the board the use of a more substantial component would be indicated perhaps with small heatsink | ||
| MITSUBISHI | TC 1498 | vertical Fechado | Verificar C461 C463 | ||
| TOSHIBA | U16 U16 | vertical dobrando em baixo | Q430 | ||
| TOSHIBA | LEM7 | vertical QUASE FECHADO E COM UNS RETRAÇOS NA PARTE SUPERIOR | Q830 REGULADOR DE 5V |
