| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| JVC | C-S2190E | Quando se liga está fora de sintonia. Demora cerca de 10 m a vir a imagem | Módulo CK10405 mudar os 4 electrol. SMD | ||
| Jvc | HRD720 | Noise bar in playback, looks like error in the guides adjustment | The problem is the 3.3uf capacitor in the drum motor. This generates Pg signal errors. Replace it and give me a smile ! | ||
| Jvc | AV25SD4EK | Standby LED changes from Red to Green as normal, but no picture or sound. Set appears not to come out of standby | Check for dry joints on the line output transformer tags. Resolder all as a precaution anyway | ||
| Jvc | HRD750 | Dead | This was due to C14 1uF, 63v in p.s.u being faulty, replaced with a 2.2uF, 63V | ||
| Jvc | AV21F1EN | Channel reception lost if tuner socket moved | Dry joints on IC522, IC521 and IC541 located in the big heatsink about middle of the main pcb | ||
| 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 | ||
| 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 | ||
| Jvc | AV-S250EKT | Set dead. Faint whistling noise on switch on. No standby LED | Replaced STR1006, no dfference. Line O/P Transistor OK. 36 Volt Zener, D614 found to be short. This zener is on the secondary of Xformer, T601. This short causes the 12 V start up supply cct, which includes STR1006 not to come on | ||
| Jvc | C14ET1EK ONWA | Picture height is reduced to 2 inches | Replace C418. It's the coupling capacitor from the frame circuit to the scanning coils. It's value is 1000uF, 25V | ||
| Jvc | HRJ265 | Capstan motor intermittantly stopping and starting | Replaced motor | ||
| Jvc | HRJ610 | Dead | Transistor Q31 in PSU leaky | ||
| Jvc | C14E1EK | Tuning drift,worse at high channel no's | Dry joints inside tuner unit, connections between edge of pcb and lugs | ||
| Jvc | AV28WZ2 | Blank raster | Replace defective TDA6111Q for Red, Blue and green | ||
| Jvc | HRD750 | Tracking does not lock. Picture runs up and down occasionally | Very Small electrolytic caps on the drum circuit board must changed They may be the bigger can type, if you don't find small ones | ||
| Jvc | AV25S1EK | Field collapse | Resolder TDA3654 as joints appear good but on application of soldering iron show to be dry |
