You probably wont get an answer as its an old 2008 posting, but "if" these components mentioned (usually black plastic vertical tubular) fitted into your sets chassis have the equivalent purpose to the chassis containing the C926 capacitor then they will be located very near to the vertical scanning IC heat-sink, this sticking up vertically from the circuit board. Sorry I cant help more but am not acquaint with this model.

I have the same problem you described with my TV. Can you explain where these capacitors are located?? I can replace them if I knew where there at.
