Audi 80 B4 Nokia rear bass speakers repair


Our problem – rotten wires under isolation. Even engineers fuck things up pretty well. Too much is done for improvement with opposite result.

I took wire of same diameter from old auto cables, connected with terminals and soldered.

Audi 80 B4 rear door panel disassemble

This door panel is disassembled for the first time. I broke 8A0 867 725 window frame rubber, but I’ll put it back with a glue. Old rubber parts tend to break very easily. Door is in great shape. Little corrosion on window raiser lever and treble speaker cable fastening. Window winder crank handle was the hardest to remove. Take your time and do everything slowly. Installing lock door handle is challenging, but try to put it half size below it's socket to fix the hook. Use long magnetic screwdriver to fix lock door handle. Foam rubber is a disaster...

KDE freezes while playing music and reading disk

I was experiencing strange freezes on Kubuntu. It started since upgrade to 23.04. It happens when PC works few hours with turned off monitor and it never happened with turned on monitor. I was using Pragha player. Also there may be extensive disk operations on background, etc. Freeze continued after upgrade to 24.04. Playback glitches and keyboard becomes unresponsive. Only hard reset helps.

I stopped using Pragha player – use VLC for music right now. Miracle happened – no freezes during past two weeks. How music player can freeze whole system? O_o

Still left annoying shit that should be eliminated: I regularly "loose files" when copying from mobile phone to NTFS drive both via Wi Fi and USB. Files simply disappear in destination folder. This error is fixed in Windows with chkdsk C: /f Also there are issues when canceling copy process to USB drive.

Another annoying crap is that sometimes KDE boots without sound with lagging start menu and slow disk read. Why such basic things suck on modern Linux? O_o

Most problem SOLVED by fresh install of 24.04 LTS but still sometimes screen won't turn from sleeping mode. Ctrl + Alt + F1 (F2) saves the day but... At least once I have problem with NTFS again. PC simply was frozed and needed chkdsk D: /f. Anyway LTS is better than rolling release.

Power bank not charging Type-C phone via USB

I have Power Bank and it won't charge type-C phone directly, but I discovered that it can charge it with so called charger doctor - cheap volt and amp meter. Just plug charger doctor into Power Bank USB, connect your phone and you have it - charges like a charm.

Kebidumei Car Cassette Player Tape Adapter from Aliexpress

Bought this shit on Aliexpress. It’s worthless junk. One good part in it is plastic case. Seller didn’t publish my review, but I had to write smth at least here. It has low quality tape head. You can get better from broken player or tape recorder. 3.5mm jack cable is very cheap and GND is soldered to one channel which produces only mono. Plastic wheels squeak and crack while playing which irritates. Also it catches interference from car electronics producing background hiss.

Audi 80 B4 не показує температуру на панелі приладів

Температура невірно відображалася й 1 дня перестала взагалі. Поміняв датчик 053 919 501 A — не допомогло, хоча під час замикання проводки датчика стрілка відхилялася. Краще не замикати 12 В, а подати 6 В на контакти термометра, бо можна спалити сенсор стрілки.

Ремонт фари Ford Mondeo 4 Estate

BS71-13A602-BE. Перестали світити габаритні діоди. Причина — найнижчий діод змок і закоротив, тому решта діодів погано світили, ледь-ледь мерехтячи. На клемі 1 мінус і 3 плюси — габарити, задній і ходове. На щастя у фарі лише 1 плата з діодами. Витягнув її за допомогою паяльника. Головне робити все повільно й акуратно. Плату тримають дві клеєві соплі. Протер спиртом, прогрів феном, закоротив контакти на згорілому діоді й інші засяяли мов ясне сонце. З дуру заморочився випаювання конденсатора на 10 мкФ, бо видався підозрілим. Узагалі діоди прекрасно світять і без нього. Наразі шукатиму заміну та припаяю новий діод, хоча можна із 2 їздити. Діоди міцно припаяні. Можна вирвати доріжки. Паяти повітрям із протилежного боку плати, залудивши попередньо ніжки. Не розумію нахрена ліпити діоди із платами без можливостей обслуговування. Лампи досить.
