    Need help with samsung le37r88bd inverter.

    Hi all, just need a but of help diagnosing this issue I have got a Samsung le37r88bd 37" lcd tv that originally the inverter wouldnt start the backlights would flash then it would shutdown, I fixed this by reseating all the connectors and plugging in the little 2 pin wire that goes in to the bottom of the inverter as it was unplugged, now the inverter will start but there is a very loud buzzing noise and eventually it will shut down I will take a video and share the link to it, I would like to know what you think is up bad ccfl or bad transformer, now the bitch here is I left my muiltmeter at my uncles and I cant collect it till the week end and would like to have a rough idea of whats wrong.
    The model of the inverter is a darfon 4H.V1448.481/c1
    The transformers are 6026b's

          That sounds like high voltage arcing, do you also smell OZONE.
          I would inspect the inverter transformers really well and see if all the legs are solder, also check the high voltage windings of the transformers.

            Hi Budm thanks for the reply, I have opened the lcd and have found a bad ccfl lamp, I cant seem to find any replacements though

              Never updated this so here is what I did:

              Received a Le37R86bd smashed screen so I stole the backlight assy out of it and put the Lcd out of this one into it and boom all working I also recapped every cap on the psu including primary. This set has been in my living room for over a year now on nearly 12 hours a day working great. Unsure why the lamp broke like it did originally maybe done in transport, but at least I fixed it
