Re: Dell 3008wfp faulty power supply
Here are photos from two of my board. Here are symptoms 1) The blue LED is on as soon as I plug in the power cord. 2), I cannot turn the blue LED off using power button. 3) the screen is black.
Is there any additional test can help pin down the problem?...Leave a comment:

Re: Dell 3008wfp faulty power supply
I replaced D22 and put everything back together. The monitor has blue light, but don't response to any button and no floating block of color bars. Is there any diagnostic procedure that I can go through to pin down other problem?
Where to check the standby voltages and voltages to other control boards?...Leave a comment:

Yes, I measure it. One side is 12.4v and the other side is 12.3v. Besides the T-Con fuse, what could be potential pitfalls?...Leave a comment:

Sony KDL 52W5100 No Picture but sound
My Sony KDL-52W5100 quit working after 3 year's service. The sympton is: 1) No picture
2) audio works 3) back light works
I checked the fuse on T-Con board, it seems okay with 0.3 Ohm. I seriously suspect either the main board or the t-con board has problem.
Consider $1500 for just 3 years, it seemsTV industry gain a pvery high margin profits. Not ready to dump this TV yet, if I can repair it. Any input is appreciated.
Here are the pictures of the boards after removing the back cover of the TV
