I'll have to wait until my new solder sucker comes in for removal, mine just died out. I'll get back Monday or so whenever it comes in.

D809 no short

I'm willing to go further if someone has the knowledge to help me out with this. I'd much rather fix this than buy a replacement board.Leave a comment:

Re: Toshiba 46rv350u No backlight, No picture but has sound
Ok so I finally had some time to replace R850 and once i powered it on it instantly blew F820
I was hoping those dirty contacts would have been the problem but I was not fortunate.Leave a comment:

Re: Toshiba 46rv350u No backlight, No picture but has sound
I'm going to have to order one. recommend any site or just use ebay and amazon?
I also read about the q860 also being the rebel possibly. How can we test this part?Leave a comment:

Re: Toshiba 46rv350u No backlight, No picture but has sound
so I opened up sr81 on both boards and they had dirty contacts. you think just changing out r850 will do the trick??Leave a comment:

Re: Toshiba 46rv350u No backlight, No picture but has sound
I have been testing both boards and getting exact same results. R850 is showing open circuit on both boards....Leave a comment:

Re: Toshiba 46rv350u No backlight, No picture but has sound
I had 5.07v between pin 3 and 4
r8141 was giving me reading in the millions...Leave a comment:

Re: Toshiba 46rv350u No backlight, No picture but has sound
Any idea how I could check for voltage getting to that circuit. My diagram skills are pretty weak
Whatever the problem is it must be common because my original board and the used one I bought have the same results....Leave a comment:
