Re: BUSH LED2497ODVDFHD, 17PW80 V2, Dead!

Sorry about the slow reply and thanks for the tips - I actually just put the TV back together and can barely hear the whine, so I think it was either like that already or isn't an issue anyway!

Re: BUSH LED2497ODVDFHD, 17PW80 V2, Dead!

Hi all, have read the rules and hope bumping/necroposting this thread is OK (seems to have been bumped a few times over the years!). I've just replaced the 5 diodes on my 17PW80 board with UF5402s and got it powering up again, but I'm now getting quite loud coil whine from the power inverter on the board (SMP-C2776, TR700 on circuit diagram). Could it be related to the new diodes? If not I'll just try pushing some thermal glue into it since replacement inverters are £20 on eBay, and this TV's barely worth more than the glue...
