Panasonic Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PANASONIC | TX-14/21GV1 | No operation, standby led blinking | Replaced c840 47uf, 25v which had gone low in value | ||
| PANASONIC | NVG30 | Operates for about half hour to an hour and shuts down | Capstan ic located on the underside of main pcb was dry jointed due to exessive heat. remove and discard plastic cover and apply fresh solder removing old. also refresh heatsink compound.i'll try extending the heatsink too | ||
| PANASONIC | TX21V1 ALPHA 2 | Bright red raster with flyback lines,shutting down after about 30 seconds with squealing from power supply | The fault was due to the supply choke to the red output stage on the tube base panel being o/c, i can only assume the shut down was due to excessive beam current, a long soak test proved all was now ok | ||
| PANASONIC | TX-2470 | Cogging on vertical elements of picture, p.s.u squealing | Replaced c808 10uf, 50v it had gone low in value | ||
| PANASONIC | NVJ45 G DECK | Appeared to be dead like c1110 1uf, 400 | Found c1125 and c1130 680uf, 20v leaking onto pcb. remove sm.tx and clean board | ||
| PANASONIC | TX21AD2DP | Stuck in standby but tripping, not the usual nvm problem and nothing s/c | Check and replace c804 1uf, 25v, c806, c807 100uf/50v in supply. use 105 degrees cap. types | ||
| PANASONIC | TC2195DRS Z3T | Smps noise. low volt and high current on usyst, no screen or sound | Fbt tlf15606f | ||
| PANASONIC | NV-HD675 Z-MECH | Intermittently shutting down with ho1 in display | Problem can be caused by stator board vek9017 but in this case the problem was the upper drum assy! the bearings seize up when warm! | ||
| PANASONIC | TX28W3 EURO 1 | At switch on a strange sound comes and goes for a few seconds, no sound and vision | Check r622, q624 and t639 | ||
| PANASONIC | NV730B D1 MECHANISM | Video heads wear very quickly | Check the back tension if you haven't done so already - it was set too high when manufactured. | ||
| PANASONIC | NVF70 | No sound via scart socket | Fit r4908 and r4910 on input/output pack, as they may be missing ! both 47Ω | ||
| PANASONIC | NV870 D1 MECHANISM | Mode switch chatters | If it still does this with a new mode switch, check the serial number. if it's prior to numbers beginning a5k... then add a 560Ω resistor and a 50v 0.68uf electrolytic capacitor in series, between pin 2 of ic6002 and ground. | ||
| PANASONIC | NV870 D1 MECHANISM | Noisy fm audio | Add a 0.01uf 50v ceramic capacitor between pin 9 of ic4509 and ground only applies to units with serial numbers prior to d5k | ||
| PANASONIC | NV-366 | Front buttons play, ff etc. don't work | Caused by faulty remote control jack socket - this machine uses a wired remote | ||
| PANASONIC | NVJ30 G-DECK | Severe patterning of white streaks filling the screen in playback. e-e is ok | C1122 in the power supply unit. it is probably leaking its contents | ||
| PANASONIC | NVJ40 | Poor picture, may clear as unit warms up | Check c27 in the power supply secondary | ||
| PANASONIC | CT20G12V | Dead | This was found to be due to the str58041 chip | ||
| PANASONIC | TX28W3 EURO 1 | No raster, only heard a pip from speakers that went after a few seconds | C623 and r628 changed | ||
| PANASONIC | NV-L20 | Poor playback and recording looks like poor heads. also shows as interference when playback appears | Check all electrolytics in secondary of switch mode power supply | ||
| PANASONIC | NVHD650B | Fault code f80. works occasionally then doesn't work at all | Tsound is a plastic piece on the motor which rotates when you press play or eject. a plastic cap fits on the spindle of the motor. this slips and doesnt grip the motor hence does not turn the drive gears. just glue or replace the part use loctite or super glue |
