| Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
|---|---|---|---|---|---|
| Panasonic | ALPHA 2W | Squeal at switch on then goes dead, channel indicator ok | Check the l.o.p transistor Q551 for s/c, overvoltage diode D854 for s/c, R564 / R567 fusible for o/c and also check C808 10uF, 63v and IC801 STR54041M and locally for dry joints | ||
| Panasonic | NV-HD101 | No picture on e-e, I.F output ok | This was due to switching chip IC3901 M51292FP on the scart panel | ||
| Panasonic | TC1400T | Int loss of signals | Check R545 for dry joints | ||
| Panasonic | NVF70 | Bad picture, may be stripy with blue spots | Change C22 in the power supply 680uF, 10V. I used a 1000uF, it works great | ||
| Panasonic | NV-G40 | Picture noisy on all channels | Transistor Q4 D1330 o/c | ||
| Panasonic | TX-21S3T | No line drive | This one had me puzzled for a while until I found that diode D861 was open-circuit intermittently! | ||
| Panasonic | NVHD100 | Narrow sync pulse output in E-E but ok when pre-recorded tape is played | Replace 3.3uF, 50v SM capacitor on hybrid IC301, If fault persists replace IC301 on the Y/C sub board | ||
| Panasonic | EURO 7 | Procedure to enter the service mode | Set bass to maximum, treble to minimum, then hold down the index button on the remote and press the v button on the set | ||
| Panasonic | NVHD100 | Dead after storm | Check the STRS6545 regulator chip and the mains fuse | ||
| Panasonic | TC15M1R | Tries to start, led lights once, and shuts down | Disconnect pin 6 of loptx, set should run with frame collapse. Replace frame IC to effect cure | ||
| Panasonic | NV-HD625 | Loss of colour | Filter BP301 may have poor internal contacts | ||
| Panasonic | CT-T14R | El diodo en paralelo con condensador electrolitico C810 vuela porque este voltaje esta bien alto cerca a 200 voltios debe ser 138v | Cambiar la R610 de 110k estaba alterada | ||
| Panasonic | P03RMK2 VJDO3D40 | Int capstan motor stops responding | Changed the IC No. BA6871S | ||
| Panasonic | 21LIT | Dead set, only red LED is on | Replace IC AN5606k | ||
| Panasonic | NV370E | Display shows dew sensor at irregular intervals and different circumstances causing the video to go in standby mode | Bouncing effect of power switch on timer board. Only one section of this double pole switch is used. Add a 1nF capacitor in parallel to this switch and use the second section as well | ||
| Panasonic | NVJ35 | Noisy capstan | C22 in Power supply fixed it for me | ||
| Panasonic | NV-H75 | Dead | Check C1003 1uF, 100v then the STRD1806 and D1004 for s/c | ||
| 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 | ||
| Panasonic | TX24DX1 EURO 4 | Intermittent dead with red standby light on, but won't switch back on, comes back on it's own, won't respond to remote or local controls | Low 5v standby supply due to diode D869 faulty, check by replacement | ||
| Panasonic | 14B3T Z375. | At switch on the set pulsates 6 times before the H.T settles at 110V and the set powers on | Replace R804 0.56 ohms. It's located in the primary of the power supply and is used for current sensing. Also note this is actually a Daewoo CP375S |
