Hi guys new here but taking this hobby serious. A couple of questions first.
What is the best way to clear out loads of dust from a tv?
And I am after a isolation transformer to make testing safer and to be able to use my scope safely, can anyone point me in the right direction with a link? I have seen one at rs components but not sure if I need to disconnect the earth from the secondary side?
Right then. The tv
Samsung ps-50c7hdx/xeu was given to me, it had a blown chip on the upper y buffer board, I have replaced the board and found shorted ziner diodes on the y main board which have now been replaced ( was given the tv in disassembled state so did these repairs before I could power up) when powering up I get very red screen sometimes goes black can't see any menus, not had source connected so can't confirm sound at this stage. Va is fine at 65v but vs states on sticker 202v, I get 201v for a few seconds then when the panel lights up it drops to 188v any ideas are most welcome
