    Vizio D65x-G4 Volume changes on its own
    by karthur
    On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.

    It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related....

    Loewe opta R125 distorted sound at high volume
    by jorpec
    Hi
    I'm restoring this vintage radio, that had a very weak sound output, after replacing the electrolytic capacitors the sound volume improved but when the volume reach the middle of the knob starts to distort, its like the speaker overdrive and saturates, but only at lower frequencies even with the tone knob at minimum on bass frequencies. i have tried with other speakers but is the same.
    Any idea what causes this ?
    Below the schematic

    Thanks...

    AVR-2802 no audio, chip questions
    by MasterCap
    I do some hobby repairs mainly of my own junk, and I don't know much programming level repair/mods.

    I got the AVR-2802 over the weekend, sold as working of course, and it worked for 1 night, using EXT. IN 5.1CH jacks, then after power down, the audio never came back. I've reset it, and get nothing on EXT IN or PHONO, despite having everything set right, hooked up right. I can hear lots of relays work tho.

    I just want it for 5.1CH analog inputs , for PC surround sound. I'm not worried about the video or most of the digital stuff for now.

    So far I've traced...

    Marantz SR5007 popping on volume change and mute in Direct Mode
    by BigOof
    Hi,

    I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes....

    CH341a can erase and read but can't write and blank check
    by hasel17
    So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :
