I don’t see any visible bulging or bad caps on the PS board but there’s a High pitch variable whine noise coming from the transformer on startup.
I’ve replaced caps before on pc and lcd TVs but never delved into troubleshooting much more than checking for visible signs of bad caps.
I read Bud's pdf on general troubleshooting but, has anyone had this audible whine coming from what sounds like the transformer?
Sometimes the TV will show the sources select screen with various artifacts and wide hashed lines on the screen in the background it seems. After the bootup "please wait" message sometimes it shows the sources select but sometimes I just get a warm grey screen.
Do these pictures and symptoms sound like a bad Tcon board?
