I have had this M.B. for about two years and have not been able to find a replacement. I Tried a Repair kit that had two IC but it did fix it. The people said they bought the set new and it has never been in for repair. What puzzles me is one of the IC had a jumper on it. I haven't seen sets with wired in jumper but only a few times. Is this normal for this particular board? I looked at Google Images for this board but could not find the jumper? IC 7600. to other side of the board. If it's been butchered before I got it I can't send it to PTS Electronics for repair. This board simply not available. Thanks I thought I had a picture.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I picked up this TV from Facebook Marketplace, original owner described it as "screen went black after a pop" and I hoped to see an obvious fuse or cap to replace. Doesn't seem to be the case, but my experience and electrical knowledge are kind of limited for this.
The power board (BN44-00445A, see attached) turns on and Vs and Va seem to momentarily have power, then they steadily drain to zero over a minute or two as if they're only getting power from capacitors. I've been measuring Vs and Va from the test pads, with and without the other boards connected to the power board... -
Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.
For my passion for technology I'm now collecting several... -
Hi,
I have this almost brand new Plasma was well stored. I would like to repair it for a friend of mine.
I have noticed that it works for few seconds then switches Off the Power_ On signal. Have disconnected boards and left maion board and power supply and still the same. The power supply with PS_ON and VA signals On stays on so it is not a problem in the power supply.
Any one met this problem in the past?...10-08-2025, 07:34 AM
