Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Hitachi | C28WS10TN | Poor starting, some times comes on then cuts out with LED going out | Dry joints along centre heatsink where the three ICs are mounted, reflow solder on ICs and then check HT 160 Volts | ||
Jvc | C14E1EK | Dead, in standby, HT present at relay RLX401, no 12 volts at C419 | R425 5.6ohm o/c, ZD402 12 volt zener s/c and C426 2200uF, 25volt faulty | ||
Mark | TVD1420TX | No video, grey picture with white lines | 1ohm resistor on the mainboard next to the connector for the rgb | ||
Goodmans | 1430RA ONWA | Volume up full, red bargraph but no sound, Picture bargraphs also at full and will not adjust | Disconnect pin 1 of MN1220, press vol down then store then resolder pin 1 - only seems to correct problem if resoldered while unit is powered. | ||
Saba | M3715 TX805 | Dead, 1.6A main fuse blown | Replace TP10 S2000A and DP21 2V7 zener | ||
Panasonic | NVJ35 | Noisy capstan | C22 in Power supply fixed it for me | ||
Jvc | HRD560 | 3/4 of the playback picture is snow may look like duff heads! | Check 3.3uF,50v capacitor on lower drum motor pcb, this is an smd type but can be replaced with standard cap mounted on its side and tilted downwards slightly to clear mech | ||
Finlux | 71G2 ID:54361330 Stereo Plus | Bottom half of the screen is black. Very distorted picture in top half. Volume weak. The programming menu, and the "Extra" menu, has disappeared. In "Service mode" Mute, M and TV buttons in sequence, all settings are set to the max. value 63 | The existing IC "SPL 40R01" in location NF10, and the connected EEPROM in location NF80, was replaced with replacement IC "SPL 51R02" and an empty EEPROM. It comes in a kit, which also includes installation instructions and a user manual | ||
Sony | KVS3432U AE2 | Front led flashing 13 times, HT at first came on at 139V then went to 75V going off etc shuting back down in protection mode | Found R854 open circuit on -15 volt line off line output transformer | ||
Ferguson | 28DG17UG TX807 CS | No start up, l.e.d flashes orange 7 times then stops. All rails on secondary of chopper seem ok | You will probably find the line o/p transformer is at fault | ||
Ferguson | 28DG17UG TX807CS | To remove the protection to assist with fault finding | Remove TL061. It's a surface mounted transistor located near the line o/p transformer | ||
Philips | 28ML8805-16B FL1.6AA | Power supply faults. BUX85F in micro SOPS defective | Change the value of C2260 to 4n7F, replace 7270 with transistor BD825 | ||
Mitsubishi | CT2227BM | Intermittent no sound or picture | Desolder, then resolder Line Driver Transformer connections | ||
Philips | 28ML8805-16B FL1.6AA | Ticking noise and line in picture | Transistor 7381 BC848C defective when hot | ||
Philips | 28ML8805-16B FL1.6AA | Disturbed sound in left channel | Check IC7009 LM833 on LSP | ||
Panasonic | NV-H75 | Dead | Check C1003 1uF, 100v then the STRD1806 and D1004 for s/c | ||
Hitachi | C1709T | Dead H.T high and tripping | Replace ZD903 and R909 39K also check ZD901 2.7v for s/c | ||
Grundig | CUC2080 | After replacment of FBT, the set starts and reverts to standby mode immediately. If the Crt heater is fed by an external transformer i.e. 6 V. a/c, the screen will show a very weak light, except in the corners | 13V. was present on pin 11 of V. output IC TDA8350Q during the brief moment when the set tried to start. The TDA8350Q was found to be defective and was replaced. Don't forget to check +A voltage after replacing the FBT | ||
Sony | KV2184 | Main fuse blasted | Replace the STR50115, also replace the mains electrolytic capacitor | ||
Philips | 2B 2B | Very low HT voltage | The HT was so low that a 60W lamp connected across the HT line as a dummy load wouldn't even slightly glow. The problem was caused by a wrongly fitted PTC, it was a 96012 type, when the right PTC 96012 was fitted the problem was solved |
