Sziasztok!
Ehhez kellene kijelző, mert a szalagkábelről lejött a vezetőréteg, a LCD panel felől. Hol lehet beszerezni ilyet, vagy bontás is érdekelne? A szalagkábel végére ezek a számok vannak írva: 9 648 059 022MFT.

Nekem ez az elso ilyen amit latok, nagyon tetszik, tobbek kozott szines kijelzo, szep menuk, BT csatlakozas, internet radio, Spotify, stb.
A problema a kovetkezo:
A hangero szabalyozo gomb vegtelenul forgathato korbe, a forgatas iranya noveli vagy csokkenti a hangerot.
Ez a resze mukodik is szepen, a kijelzon valtozik a hangero erteke, de a hangerot nem szabalyozza.
A hangero neha valtozik... magatol. Nem tudom mi szerint, de nem fugg ossze a kiirt ertekkel, nemitva is pont ugyanugy szol mint maximalis hangeron.
Szerintem software baja van, menubol csinaltam egy gyari visszaallitast, de nem befolyasolt semmit.
Erre keresek otleteket.
Minden jot,

Hello,
Last week I picked up a nice Kenwood KA-3500 40watt intergrated amplifier in pretty good shape.
Upon using it a bit more, I noticed a bit of distortion at high volume, more so in the left channel. I checked the DC offset at the speaker terminals, and the L channel said 100 mV, while the R was 25 mV. I understand this isn't so good for the L channel at least, but unfortunately this amp doesn't have any DC offset adjustments. Am I right in saying that to fix this I'd have to replace the output transistors?
--
On a related issue, in the service manual I found the section on BIAS adjustment, and I read online how it can affect the DC offset. So I hooked up my voltmeter to the test points, and I got 4 mV on the L, and 8 mV on the R. In the manual it says should be 40 mV.....(!). Is there something wrong here? I tried carefully adjusting them, but they only go to 30mV with the pots fully on, this doesn't seem right to me.
--
I compromised at 20 mV BIAS for both channels, and now the DC offset is 50 mV for L, and 5 mV for R, which is better, less than half what they were. I'm wondering, will I damage anything doing this, should I put them back to where they were?

The service manual is on site here.
Let me know if you want me to upload an english copy of the Owner's Manual, it has a better schematic in it all on one page, easier to read.
I've also included some pictures. They're not my actual unit, but mine is exactly the same, but less dusty.

Thanks for reading this. Many thanks in advance, and have a peaceful Palm Sunday! :taps2:

Sziasztok. Adott a cimben szereplo tipusu erosito, ami a kovetkezo furcsa jelenseget produkalja: bekapcsolaskor a rele meghuz, mintha minden redben lenne, de a hangsugarzok tokeletesen nemak. Tapfeszek rendben. Kimeneteken 0V. A rele pogacsai erintkeznek. A kovetkezo ponton alltam le: a bekapcsolas pillanataban a 2 kimenet kozott nehany ohmos ellenallas merheto, meg mielott a rele meghuzna. Kikapcsolva nem merheto ellenallas a 2 kimenet kozott. A rele a bekapcsolast kovetoen eleg hamar, 1 -1,5mp utan mar meghuz; a SVI3203 18. laban -13V helyett -11.5V merheto. Vajon a SVI halalozott el?
