I have a vizio vz37l tv. When i turn it on the screen lights up, however there is no picture on the screen. the sound works, its just no picture on the screen. I read on a couple of the posts on here, and figured the proper course would be to replace the t-con board. I just finished replacing the tcon board and still the same thing. I called vizio about the problem and they say that if the screen lights up then the problem wouldn't be the backlight inverter boards, that it might be as simpl

I think I shorted out the power supply board on my Onkyo HT-R667. I was replacing some the capacitors to repair a hdmi switching issue. I was testing the repair with the top cover off. While it was powered on I accidentally touched the metal top to the top of the power supply board CMKM-P3X. There was a spark and the unit turned off. It won't turn back on. No lights. Can it be fixed or can I purchase a replacement board if this is even the issue. Thanks

Hello! I'm having the infamous black screen issue with my Viewsonic N3252W. I initially replaced the Power supply, because that looked like it was "the fix" for this particular issue. I powered it on, and I was getting the same problem. There was a faint picture (you need to look at the screen from a certain angle, with an appropriate amount of light shining on the screen.) with no back light! All of the voltages coming off the new PSU are right where they should be, including the 24VDC to the

Main Board? Had issues for years, where I had to unplug once in order to get the tv to turn on. Then one day, it would not turn on. The TV shows a quick lightening of the screen like it is going to turn on, but nothing appears. It also clicks once or twice. Took to a repair shop and they diagnosed with main board failure and refused to fix due to lack of parts. Do you think it is the main board and where would I find one? I am pretty handy, do you think I could DIYthis job?
