      LG 60PK550 Logic Control Board EBR63450301
      by Yanleb
      Hi all, I just want to share the repair of my 60PK550-UA TV set.

      The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

      But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

      All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
      C57: 3.30V
      C61:...

      Electronic Goldmine has replacement Irons for the ZD-978 or similar model number this the one that has the sleep function
      by sam_sam_sam
      This is a new item at Electronic GoldMine that has arrived within the last few weeks

      Here is the link for them I know for sure that it works because ( I tried it on mine soldering station ) I bought two of them and I just bought two more of them so I have some extra replacement ones in my parts bin

      Stahl Tools DDDS Replacement Iron for DSDS Stahl Solder Station
      https://theelectronicgoldmine.com/products/g28392

      One note it will not work for the ZD-917 or similar model number that does not have the sleep function that are the same iron but the plug only...

      triac phase control 0-100%
      by harp
      Trying to understand which properties of circuit affect triac phase range, is it possible to control near whole period, or it have some limitations - on net found a couple circuit, that claims almost full control, but in the past I build some simple circuit and remember that it do only half of control over triac?...
