H Mark,

Don't have set listed under Bush and you didn't give a Grundig model, so how about invertor details or a piccy - Chris

Sorry in a hurry this morning. Grundig model GU15WDPCX exact same TV Goodmans model GTVL15W17HDF. Other number was Charles Hyde number for Psu/inverter board, which is discontinued. Both TVs work fine for a few minutes, then screen/ backlight goes off. No sign of distressed capacitors, or hot spots or dry joints on board. I'll start taking caps out later and test individually.

Thanks

Mark

Hi Mark and thanks.

There is some history with fault you describe under Grundig - turned out to be duff tubes. Trust not so in your case. Incidentally, what was the PS/invertor model out of interest  ?

All the best - Chris.

PS  - Your second seems to be a Bush LCD Tv not a P/Inv panel. Go on, give us a piccy, make our day.

Hi Dave,

You're talking Vestel and those 12pf caps feeding the tube sockets, I guess. All the best - Chris.
