    Olevia 537-B11 fault

    Looking for some more help with this one now, had it for some time and need to make a decision, previous owner rekons he bricked it during a firmware upgrade, but think it had issues prior to this, anyway only getting a blue standby light on the front, when power is applied in the back get a brief flick of red led lights allover the main board as if its switching on followed by a small static click noise I think coming from the psu, then just one steady led on the power board. I have replaced most of the caps on the secondry checked for shorted diodes and transistors no luck! none of the plugs have any pin markings, as this set came from the states spare boards are not available even if I did know which board was faulty, any help apreciated

    thanks Ronnie

    I'm only getting 5volts from the psu to mainboard, as this tv is from the states I was confident I would get some responses on this forum, would be a shame to trash the tv, can anyone help me out?

    thanks Ronnie

      If something went wrong during a firmware upgrade, this set may be bad. However, there is a covered inverter board on the left hand side of picture #1. Post a pic of this when you get a chance.

        Thanks for the reply Dgtech, removed the cover and took a pic, there is a slave invertor on the other side, I did try powering with them unplugged from the psu, as said as soon as power applied red leds flick on for a second allover the main board.

        thanks Ronnie

          There is a little white fuse near the main connector on that slave inverter board. Check this with a meter and report back.

            Hi Dgtech, thanks, that's the master invertor, fuse checks out ok, there is power briefly to the board 22v at switch on?

              Anyone offer any advice on this set? or might have a working main board to sell?

              thanks Ronnie
