Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Samsung | TXG2547 K51A | No power, Voltage not changing on pin 18 IC901 SZM-368ET2 | Check dz906 short, key-in 1 pin 9 of ic901 | ||
Grundig | M70-495 CUC-3800 | Dead set | I replaced the BU546 transistor in the power supply and resoldered some paths on the PCB. An intermittent soldering path to the collector of the transistor was the reason for the destroyed BU546 | ||
Philips | 28PT4521/16 MD1.1E | Fails to stop at station when tuning | R3568 100Kohmat side of L10 connector | ||
Sanyo | C25EG95B EC3-A25 | Dead set no start up | Replace R321 120K | ||
Sanyo | CE32WP2 WB2-A32 | Dead set, standby L.E.D lit | Check capacitor C634 2n2, 2KV in power supply for o/c or s/c | ||
Sony | FE-1 | No teltext just P100 | This problem was caused by Q405 2SC2412K being s/c | ||
Sony | FE-1 | No power although relay operates main p.s.u inoperative | Check IC606 STRF6654 for failure, also check resistors R659 0.33ohms,3w, R660 0.39ohms,3w, fusible resistor R603 0.1ohms,0.5w and capacitor C625 100uF,25v | ||
Thomson | ICC17 | Standby led fault codes and meanings list / standby led flashes then pauses | Code meanings are as follows: 10 = child lock mode, 11 = timer mode, 14 = there is no response from Iv01, 15 = there is no response from IS40, 20 = bus access prohibited by software, 21 = bus data line held low, 23 = bus clock line held low, 25 = switched 5v supply missing, 26 = crt is not warming in the allotted time, 27 = deflection failure more than three times, 28 = IF01 guard voltage pin 8 exceeded, 34 = no response from the nvm chip IR03, 36 = incorrect address passed to bus handler, 37 = unexpected level on NMI line power fail, 41 = bus data line not recoverable | ||
Grundig | ST82-774 TOP/EURO | Not starting, power supply working perfectly display present | Replaced the horizontal deflection power driver ic TDA8140 | ||
Grundig | CUC6310 | No east-west | Check R569, TDA8145, D566 | ||
Panasonic | TX-14B4T Z185 | This set had a bright picture, no off air video and no video via scart | The cure, thanks to Panasonic technical was to replace the memory chip I702 X24C | ||
Vestel | 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 | ||
Sony | KX27PSI | Almost totally dead. No video or audio whatsoever. Only the clicking sound of two power relays when the set is turned on, and conversely at power down. The green/red lights on the front panel do appear. Repeated failure every 2-3 years. Why ? | An insight into what TV engineers did, after speaking to Sony UK: a 0.47K resistor replaces L656 in line to Q651 B. b 0.33 ohm resistor added between L650 and Q651 E. A resistor also replaces L657. Still lasted only 2 years. Any better ideas ? | ||
Sharp | 66FW53H FW | Dead only neon lit | Check D735 across 150v rail, if s/c you will need to replace the opto and the D735. Check Q601 line o/p transistor as this may also be leaky | ||
Sharp | DV5131H S3B | Intermittent failure of Q603 | Replace C601 low in value | ||
Sharp | Unknown | Fault like soft crt | I had 3 of these sets which all looked like soft crt, i changed the crt base from a known good set and all was ok i do not know the fault on the crt base yet but it was as good as new | ||
Ferguson | ICC8 | Line transistor TL19 was short circuit. After replacement the transistor shorts again | Change capacitor CL21 | ||
Grundig | T55-731 CUC7303 / FET TYPE | Dead bridge and chopper transistor s/c | If no D663 fitted this is version 2 has fet and UC3843. Failure of p.s components caused by C669 dry jointed. Check/change FET BUZ90, D667 BA157, R661 4.7k not 220r version 1, R666 and R667 56r 1w, R663 10r and the UC3843. All values for 20" | ||
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 | ||
Philips | 28PW6322-05 MD1.2E AA | No picture and no sound and when switching on, the high voltage transformer makes a sound | The capacitor in pos. 2420 was bad it produced smoke after some time |
