Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
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 Fechado | Verificar C461 C463 | ||
MITSUBISHI | TC 2018 | liga e em seguida desliga | D553 | ||
Mitsubishi | Various | Int RGB variations/fback lines | Dry joints crt base | ||
Mitsubishi | M5 srs | Tuning drift . Fit previous mod if not done alread | Change R120 220k to 100k , Change R121 180k to 82k , Change R126 100k to 47k remove R736 22k and fit an 8k2 & 15k 1/6w R-Met | ||
Mitsubishi | M5 and AV1 srs | TUNING DRIFT OR INCOECT AFC OPERATION | FIT 180k + IN4148 IN SERIES FROM TUNER PINS 2 - 6 ( PIN 2 -180k->l- PIN 6 ) | ||
Mitsubishi | M5 and AV1 srs | RGB OUTPUT SC ( IC660 TEA5101B ) | CHECK FOR 12v ON WIRE LINK TO PIN 2. IF MISSING OR LOW PICTURE WILL BE AWFUL AND A1 WILL NOT SET COECTLY. Q6E8 LEAKY. REPLA | ||
Mitsubishi | M5 & AV1 srs ( 2 | POOR PICTURE . | REMOVE Q6E2 , 6E3 , 6E4 , 6E5 . DECREASE RED DRIVE BY '5' POINTS , INCREASE BLUE BY '3' STEPS . THIS HAS BEEN DONE ON LATER S | ||
Mitsubishi | M5 & AV1 srs ( 2 | POOR PICTURE . | CHANGE R521 FROM 82k TO 56k AND FIT ZENER DIODE KIT , Pt No 264P45090 | ||
Mitsubishi | M5 & AV1 srs | WHEN SWITCHED ON LED COMES ON GREEN , HT & LT PRES | CHANGE C955 TO 3300uF 35v ( Pt No 181P353000 ) EEPROM MAY NEED RE-SETTING . | ||
Mitsubishi | M srs AV1 srs | RF PATTERNING ( SIMILAR TO VIDEOCRYPT ) | FIT RF LEAD Pt No H24P001010 |
