Hi all... I acquired a Philips 47PFL3603D/F7 LCD TV that would seem to be 8 1/2 years old. I had no idea if it was working or not so plugged it in. Immediately I heard a pop and some crackling and could smell fried electronics. It didn't persist and there was no smoke so I pushed the on button... no additional noise or smoke. Blue screen with "no signal" displayed. What the heck... this thing is working? I don't have a cable out in the garage so I grabbed a laptop and put HDMI into HDMI 1 and it auto detected the signal.
Most of what I found when I searched here a bit were about no power but this is working. It does seem a bit dimly light though (back light?)
I did notice that there's a bit of a clicking noise when you put the power cord into the fitting but it only makes that noise when it makes contact and doesn't keep clicking. Seems to be coming from one of the blue rectangular block "hi-pulse withstanding" caps (inverter transformer driver?).
Shop Jimmy has a 44 part kit to deal with this power supply but I'm just not sure I need all those caps etc. So here are my questions. If I replace JUST the toasted parts that you can see in the pic should that take care of the dim screen?
Looking at the good pic of the back of this board that I found on a thread here it looks like I need R752 / D751 / R701 and ZD701 / ZD701A / R710 / C705.
Now for the serious question - how in the heck do you remove & replace those tiny things. I mean I can barely see them and needed to zoom the image to even make them out. I would need some serious mag glasses to work on them. I'm pretty sure I don't have a micro-fine point soldering iron either.
Any advice would be greatly appreciated.
