Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Panasonic | NVFS90EG | Power supply problem, high frequency sound only ! | Check / replace C9 1uF, 400V | ||
Finlandia | C/D 66KZ6/F | No power mains fuse intact | Check Replace C706 10uF 350v Cap In Psu o/c also check / replace T511 S2000AF H.out Transistor | ||
Mitsubishi | BD28S 11AK19 | Narrow E/W Pic | C630 o/c | ||
Toshiba | 210T6BZ | Distorted sound / banging | Voltage at C832 over 25V! Replace Q809, C866, C869, C864 and resolder dry joints in PSU | ||
Philips | 28ML8805-16B FL1.6AA | Clips picture at bottom when warm | Vertical deflection IC defective 7450 TDA3654Q | ||
Philips | 28ML8805-16B FL1.6AA | Some front panel indicators are dark | LEDs are tired | ||
Philips | 28ML8805-16B FL1.6AA | Dead | Fuse open 3.15A, transistor 7216 ON4827 = BUT12AF shorted and solder joint of SMD resistor 3305 11K cracked located on PS control board | ||
Firstline | 1433GR | No picture, no OSD | Zener diode D219 12V shorted. Check capacitors C608, C606, C617, C619, C411 and resistor R256 39 ohm, 1W. Unreg. voltage to R256 should be 16-17V with no change when warm | ||
Decca | D14TT92 | Dead set, with 300v across smoothing takes a very long time to discharge, watch out! | Check RP06 3.9M ohm for O/C, the one I had had nothing else gone | ||
Sony | KV28WS2U | OSD volume bar present continuously. No functions available | Front panel tactile switches leaky. Replace same | ||
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. | ||
Goldstar | TV-Vid Combi Model: KY14V30 | Squeeking sound from chopper transformer | Shorted voltage regulator, zener diode or h-out | ||
Orion | 5190DK | No secondary supplies | Check / replace C418 100uF, 25v, C489 100uF, 40v, C425 1uF, 400v, posistor PTC401, R422 5.6ohms, 1w and the chopper transformer | ||
Thomson | TX807 | EHT at switch on then goes dead | Frame i.c. s/c TDA8177 | ||
Panasonic | TX33AK10 EURO 5 | Strange picture / bleary / movement blurr etc etc | This problem was caused by eeprom corruption, once the eeprom was reset the fault was cured note that after a reset reinstallation i.e. tuning will be required | ||
Thomson | 28WS23E ICC17 | At switch on set starts-up with lots of sparks inside CRT socket, then switches to standby | Replace FBT - HR 8317. There is a repair kit available from Thompson for this , which includes a new loptx, tuning caps and a couple of coils. There are also some surface mount resistor value changes. It's Pt. no: 35175720 | ||
Philips | L6.1AA | Sound goes off and no remote control functions when heated | T7505 in +5V supply, replace 482213041344 | ||
Sharp | DV3760H | Will not work, standby red LED flashing | C604 in the 12V line is bad | ||
Philips | 29PT785C G88 | The set goes into protection and tries to restart. The tube shows no horizontal lines | After disconnecting the horizontal plug the +148V and CRT high voltage remained stable. The small pcb on the tube scan coils with 5 or 6 pins was dry jointed at copperside | ||
Telefunken | TX92F | Keeps on burning the surge resistor 280ohm 5W in series with the chopper transformer | Replace the chopper transfomer it has a short either on the primary or secondary side |
