Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
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 47 ohm | ||
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 560 ohm 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 |
