Trio-Kenwood: KR-3010 [Radio] S.N.962845 / Does not work, the final floor and prefinal floor defect with many burned component/

I greet you! I would need the scheme of this "vintage" amplifier that needs to be "restored". The problem is that in the prefinal and final floor I have many "fried" resistors well, their value cannot be identified.I replaced the defective transistors: 2SC1509, 2SA777,2SB690 and 2SD 796 (each 2 pcs.) and the electrolytic capacitors adjacent to them. I could not go further because of the carbonized resistors that I do not know their value (I can only guess that they are values small, in the order of ohms). The schematic diagram I downloaded, from the address received by the kindness of a colleague is not complete - it is a single page (missing Q29-Q30-Q31-Q3 and resistors R115-R116-R117-R118 which are completely carbonized, at other resistors I could see their value).Thanks in advance!
Finally, I found the missing part

If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.

Kenwood kdc-m6021 tuner probléma.
Sziasztok. A fenti autórádióval van gondom. A hibajelenség: tuner üzemmódban nem szól a rádió( még zaj sincs), nem lehet hangolni, nem reagál a két hangoló gombra(<< >>). Próbáltam átállitani a menüben manual-ra, de akkor sem reagál a gombokra. A többi gomb(FM,AM, programgombok, stb...) tökéletesen müködik. Ha a menüből akarnám az automata hangolást elinditani, arra sem reagál. A két hangológomb egyéb üzemben tökéletesen teszi a dolgát. Nincs belepiszkálva, nem volt még megbontva sosem.. Mi lehet a gond??? Köszönöm.

Kenwood KRF-V5030D
Sziasztok, jó estét Mindenkinek! Kérek szépen egy kis segítséget, hátha valaki már találkozott hasonló hibával. A címbéli KRF-V5030D tip. erősítő előlapján a nyomógombok nem működnek. De csak a gombok; a hangerő szabályozó és a funkcióváltó encoder működik, valamint a távirányítóval minden működtethető. (Esetleg a távval nem lehet a frontpanel gombjait hatástalanítani?? Sajnos nincs hozzá magyar nyelvű kezelési könyvem.) A panelt nagyjából átnéztem, a 0,047F-os kondit kicseréltem, mert kicsit mintha ki lett volna folyva és félig rozsdás is volt, találtam egy forrasztási KH-t is, de a gombok ettől még nem éledtek fel. Valaki találkozott már hasonlóval? Előre is köszönöm Mindenkinek, aki segíteni tud. Üdv: pianista
