    Sansui SV 1402 IC - TV set

    Hi, guys.
    I'm looking for the service diagram.
    Looked around other sites, but nothing!
    Just need to see voltage at horizontal driver [I only get 4v at collector... I'm intrigued; transistor is OK].

      SANSUI SLEDSC-32HD TV not booting, No stand-by led
      by Neddsme
      I have a 32 inch Sansui android TV that stopped booting. i checked the motherboard for any power failures but it seemed OK to the best of my knowledge. The TV does not have a dedicated power supply board so i could not do any isolation but here is a list of all the things i think were relevant to test.
      if i missed anything you let me know;
      DDR (1.5V) = 1.484V
      VDDC = 1.000V
      VDDC_CPU = 1.151V
      VDD1V2_DM = 0.000V
      3V3_STB = 3.315V
      3V3_M = 3.307V
      1.8V_M = 1.803V
      ALL KEYS = 3.310V
      5V_STB = 5.142V
      5V ...

      Problem with Samsung HT-DB120
      by stomanata
      Hi,
      this system has mainboard HT-DB120/THA25.
      Display working and also i can switch modes, but there
      is no audio.
      I noticed that resistor R100 is heating up.
      I found wiring in attach, but there is diferences.
      1. In this wiring 1st pin of resistor is attached to diode bridge and
      second pin is attached to Collector of PQ5. On PCB is not the same.
      2. Resistor R100 is labaled as 10ohm, but it is 22ohm. Even colour
      code (red, red, black, gold) show 22 ohm.
      3. Emitter of PQ5 must go to PIC4 (7812), but this also is not true.
      So, it seems...

      Board View files - pay sites
      by dicky96
      Hi guys
      I trust this topic is OK for discussion here

      When I am googling for board view files I find a lot are on various pay sites. In particular I find a lot of links to an Indonesia forum but it seems I have to pay (VIP member) to down load them: For example I am currently looking for a boardview for Asrock Z87 Exteme4

      I know a lot of folks here kindly share boardview files and schematics for free -and I doubt the sites charging money actually have any sort of intellectual property rights to sell them

      Having said that I am not adverse to paying...

      Sansui G-7700 receiver blows fuse
      by woaimi
      A colleague gave me this Sansui receiver. He mentioned it was still playing until recently (couple weeks ago) lost its power and he thinks it blew the fuse. I brought is home opened up and sure enough the 10A fuse is blown. I found a spare one at home put it in and instantly blew that one too. I'm hoping some experienced users here would direct me in the right direction to bring this nice piece of art back to life. Having read through some posts in the other forum regarding this receiver, I realized this is not an easy task but possessing a nice Sansui G-7700 and learning new skill that what got...

      Sansui AU9500, capacitor blows
      by Fripacks
      I have Sansui amplifier AU9500,, no sound, I found fuse 2 amperes, 7 amperes burns, I found too 3.3 uf 100 volts completly bulging under driver board, 1 transistor output 2SA679 shorted,and I found too the 4 capacitors 4700UF 63 volts they have not good value, I changed all these components and one of 2 capacitors 3.3 uf 100 volts is going very hot after 30 seconds, do I have power supply problem?
