CB5020 P58SC
|
Tuning not stopping | Replace r116 120kΩ this was open circuit | ||

CW28C33N
|
Dead. in safety mode | Looks like l.o.p.t but was traced to small decoupling cap on 200v line on tube base, dead short | ||

CK-5320ZR SCT11D
|
Field collapse | Check r410 1Ω in feed to d403 for o/c | ||
| SAMSUNG |
CB7230WT
|
Vertical output problems, vertical output ic fails repeatedly ! | Fit a new ic, clean old heatsink compound, add fresh compound thinly on the surface. now disregard all the other modifications previously suggested and add a large heat sink on the existing heatsink screw another one on top | ||

TXG2547 K51A
|
No power, voltage not changing on pin 18 ic901 szm-368et2 | Check dz906 short, key-in 1 pin 9 of ic901 | ||
| SAMSUNG |
CB5012Z P58SC
|
No colour, stuck on secam only | Check r514 100k open circuit or very high value | ||

| SAMSUNG |
W124W6VN
|
Picture darkens and lightens continually | This was due to a faulty first anode potentiometer, as its part of the l.o.p transformer a new l.o.p.t had to be fitted | ||
| SAMSUNG |
TXB1940
|
Red led blinks on / off, tv does not turn via power button and/or remote but after 20 minutes or so it turns on and works fine | Replace r902, r901, r905, r903, r900a, q902, and possibly the two one small and one large capacitors in the section labeled as the power supply. the board will be black under the components that are bad. q902 is an npn transistor and is hard to find. | ||

SV-2303 SV633
|
Intermittent functions | Check for dry joints on mode switch and clean off any grease inside the switch | ||
| SAMSUNG |
CB7230WT
|
High pitch frequency squeal from transformer | Fix, by replacing the main transformer which costs up to $350 australian dollars or doing it the cheaper way covering the capacitors around the transformer in glue as they cause frequency to run through to the main transformer which make this noise | ||

CT566 K51A
|
No power | Voltage not changing on pin 18 ic901 szm-368et2 | ||

20A5
|
Partial field collapse | Check ic301 tda8350q and the 2 associated unmarked capacitors 10uf and 100uf, 63v and the 10Ω,5w ceramic resistor across pins 3/5 of the above chip | ||
| SAMSUNG |
CB7230WT
|
Vertical failure common fault | The reason for the failure is because the yoke is low impedance. the tda3654q i.c. has been designed to handle 12Ω and over. heat is the reason it destroys itself, the best cure is to place a small cpu fan on the heatsink | ||
| SAMSUNG |
CB7230WT
|
Power supply flutters and standby light dims out | Replace mains filter capacitor 220uf 400v, also make sure the 4 capacitors in the primary are replaced if they havent already been |
