Panasonic SA-AK47 néha nincs stby. Megoldva
Sziasztok! A tulaj elmondása szerint időnként kikapcsol menet közben, ilyenkor a stby LED sem világít. Legutóbb már nem is tudta bekapcsolni... Namost nálam már 3 órája működik folyamatosan, a stby -tápfesz 6,7 V körül van. Mi szokott ilyenkor szórakozni ?
Pioneer vsx-831 firmware frissítés hiba
A fenti erősítő  frissítés közben megszakadt valami oknál fogva, se hang se hdmi kimenet nem működött. Majd a pio honlapról a legfrissebbet letöltöttem,  usb-n elindítottam, majd kb 1,5perc után 0-81 error hibaüzenetet kaptam,  ezek után már az erősítő bekapcslásnál a "please update " jelenik meg,  de sajnos hiába indítom  újra  a procedúrát,  mindig ugyanaz 0-81 error.  4 pendrive -al próbáltam már fat32-re formázva,  de semmi. Esetleg valaki jártas  ebben? 
 
Kazettás magnó elöregedett szíj meghatározása
Üdv Mindenkinek!

Van egy (száz)ezer éves Tectron N-16 Rádió-kazettás magnó, amire az egyik családtagom szemet vetett.
Sajnos az idő vasfoga megette a motor meghajtószíjat. Megigértem, hogy rendbe hozom neki, és majd használhatja.
Ti hogyan méritek meg/számoljátok ki ilyen esetben a szíjméretet? Nem találtam róla dokumentációt.
Köszönöm a segítséget előre is.
advice for repairing a DBX BX3 power amp (fused power transistor)
 
i have a very nice vintage DBX BX3 amp on which at least one channel fused.
power transistors literally burned down.

it is a very nice piece of hardware (4 channels with BTL capability 4x125W or 2x300W)
I would like to fix it myself. Having an electronic engineering degree, i think I should be able to undertake that venture but I never practiced (i've been in software for the last 40 years...)
So I need some guidance on the methodology to diagnose and track what went wrong.

I do have a scope, signal generator and I guess all required tools, as well as the schematics of the amp.
what I need is some help on locating the key parameters to measure and how to incrementally explore the different stages of the amp to find the faulty sections.

I guess I need to isolate the different sections of the amp but then, what ?

any help and advice will be highly appretiated.
