MITSUBISHI Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| MITSUBISHI | CT-21M2 | It searches for tunes but does not capture channels. | Agc problem. open 18k resistor r160 | ||
| MITSUBISHI | CT-1447EPM | There is no contrast. | D554 (1n4148) | ||
| MITSUBISHI | CT2125EET CHASSIS EURO10 | Does not synchronize horizontally and image is out of phase | C506 and c509 with problems, they are next to tda2579a | ||
| MITSUBISHI | CT-1447EPM | There is no sound. | Transistor q3a3 (jc501-q) | ||
| MITSUBISHI | CT-21M1EPM | No sound. Only with the volume control at maximum can you hear it, and even then, only with your ear very close to the speaker. | Replace l301 | ||
| MITSUBISHI | TC-2090 | Turns on after a few minutes, working normally | C887 (100uf/16v) | Replace with 100μF/35v | |
| MITSUBISHI | TC2051 | Vertical colored lines | R518 (4k7) | ||
| MITSUBISHI | TC-2030 | Dead | C912 and c71, check the neon lamps | ||
| 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 | ||
| MITSUBISHI | CT29B2STX | Various faults, dead, int. dead, poor frame, poor e-w | Change all electrolytic capacitors in the primary. check all large electrolytics in the secondary ie bigger that 470uf, check all capacitors around ic950 error amp.. most capacitors you will find are leaking electrolyte. might be a long job!!! | ||
| MITSUBISHI | TC 1498 | Vertical closed | Check c461 c463 | ||
| MITSUBISHI | TC 2018 | Turns on and then turns off | He entered |
