Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
MITSUBISHI | CT2125EET Chassis EURO10 | Não sincroniza Horizontal e imagem desfasada | C506 e C509 com problemas, estão junto ao TDA2579A | ||
MITSUBISHI | CT-1447EPM | Não tem som. | Transistor Q3A3 (JC501-Q) | ||
MITSUBISHI | CT-21M1EPM | Sem som. Só com controle de volume no máximo se consegue ouvir, e ainda assim, só com o ouvido muito próximo do altifalante. | Substituir L301 | ||
MITSUBISHI | TC-2090 | Liga ao fim de alguns minutos, funcionando normalmente | C887 (100uF/16V) | Substituir por 100uF/35V | |
MITSUBISHI | TC2051 | Llinhas coloridas na vertical | R518 (4K7) | ||
MITSUBISHI | TC-2030 | Inoperante | C912 e C71, verifique as lampadas de neon | ||
Mitsubishi | CT29B2STX | Line output transistor s/c, repeated failure | Replace the four caps in the power supply C905 470uF, 35V, C906 470uF, 50V, C909 2.2uF, 50V and C920 100uF, 25V also note transistor varies with different size c.r.t. | ||
Mitsubishi | BDS29S 11AK19 PRO | Picture is black with faint green retrace lines, sound etc. ok | Changed TDA6108JF on CRT board, and nearby 10uF electrolytic which looked damaged. Fixed fault. A resistor next to the capacitor had been changed before but tested okay this time | ||
Mitsubishi | CT25M2TX | Frame collapse, destruction of AN5521 frame chip at switch on | Replace the AN5521 then replace the 47uF, 35v electrolytic in the power supply. Also check the 330uF, 35v capacitor next to the frame chip for leakage | ||
Mitsubishi | CT29B2STX | Blank raster with sound / field collapse | The field output chip IC451 TDA8178S was faulty, as this original Mitubishi part was no longer available a kit had to be fitted no.H27PO14010 for this model, this uses a different chip - type STV9379 | ||
Mitsubishi | CT2227BM | Intermittent no sound or picture | Desolder, then resolder Line Driver Transformer connections | ||
Mitsubishi | BD28WS 11AK19 | At switch on front l.e.d turns green, blinks 3 times then set returns to standby. All h.t voltages rise, then fall away as set goes into standby | Dry joints IC807 | ||
Mitsubishi | CT29B2STX | Severe NS bowing | Check for leakage of the small electrolytic capacitors on the vertical correction pcb at the right of the main pcb, check C4014 in particular and if found to be faulty also check transistor Q4009 2SA950 which may also have been damaged | ||
Mitsubishi | BD28S 11AK19 | Narrow E/W Pic | C630 o/c | ||
Mitsubishi | CS40503 | Sometimes will not power up, missing 15 volt standby | Replaced D982 and C982, both leaky |
