Technika x22/14c Backlight issue..component part number

[is_it_a_bird]

Hi

Got the TV with backlights shuting off after 2 secs, the two caps have blown on the inverter, took a guesstimate and put some 10pf 3kv caps in, tv booted up and was happily playing away for a few hours, turned it off and on a couple of times no problems, then tried turning on nice little crack and the problem is back.

I have no schematic nor an idea of what size caps are supposed to be in the inverter, any ideas, should I go with 10/15pf 6kv

Thanks in advance

3kV is quite small, I would try 6kV for those caps, I know budm usually uses 5~6kV caps.

10pF seemed to work the last time... no idea what the originals were??

No both blown out the board, cant find any info, have been cheeky and asked an ebay seller to read them off but no response :o(

Could try the trick "trying to verify if my boards are compatible, as have heard they were also produced with 22pF cap" Has worked before for me.

Just read on another forum post with the same inverter that they are 9pf 3kv, so I have another fault with the TV, I do not think its a ccfl tube as I have had the tv running with no dim lines, for quite some time.

Will have another look now I am not sure if one of the ccfl leads shorts to the frame as the wires do look quite tight around it.

Fitted new 10pf 3kv caps just in case and it was still the same, replaced the two 16v100nnf caps and everything seems to be working ok
