    Sansui TV2510: La8517jg

    Hello boys,
    I need to fix this sansui tv, it works fine for a while, then, when it gets a little hot, the screen goes white and it won't accept commands from ir and buttons until it cools off.

    I found out this LA8517JG thing, that is a 3A/23V Step-Down DC-DC Converter, stops working when it gets hot, infact it outputs only 2.6v instead of 5V, as soon I spray it with the freezing spray it starts working again and tv works normally.

    Problem is I can't find it anywhere that is not on aliexpress and even then they don't provide a spreadsheet to be sure I'm not waiting a month for a thing I don't need. I found an auction on ebay but it's sold as an audio processor

    Anyone knows if there's something I can use instead?

    BTW, the input and output filter caps are OK in that section?

      Yes they are.
      Thanks for the link, the ship from china, so 30 days wait time.
      The reason I was looking for a datasheet is because I found a listing on ebay where they are listed as "5PCS LA8517JG Audio Signal Processing Circuit SOP8 IC"

      I guess I'll have to wait and order from china.

      Thank you budm for your reply.

        If you order Aliexpress Standard Shipping or Epacket, shipping takes 1-3 weeks. Economy shipping takes 1-3 months or more (mainly due to custom delays). This applies to Canada. Not sure for SA.

          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 ...

          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...
