Hello!
First of all, please forgive me my English, it is not my mother tongue...
I have a television set (Philips MD1.2E AA) of which the HOT was a short ciruit. I replaced it and the fly-back capacitor as well. The man in the store gave me a BU1508DX instead of a BU1506DX which was not in stock (but which was in the TV); he said it was compatible. (Is there anyone who knows whether this is true?) After inserting it, it immediately broke down again and I took it out: it is as short-circuited now as the original one. I can't measure a short-circuit in the primary circuit of the HV-transformer. Is it likely that there is one on the secondary site? If chances are high that after replacing it (and maybe some small other parts) the TV will be okay again, I would not mind spending the money. Does anyone have an idea about the price of such a transformer? The power supply is making hick-up sounds. Another peculiar thing: You know the sound a light-bulb makes when shaking it? The same sound comes from the picture tube if one moves the TV gently e.g. when putting the back side on again. It is also similar to the "tsjinggggggg" sound my monitor makes after pressing the degauss-button (without the first "click"). Is there a chance that there is a short-circuit in the tube so that it demands too much energy from the transformer and thus from the HOT?
I hope someone can give me some tips, thank You very much in advance!
Yours sincerely, Rene
