Re: Laptop Blackout

This seems to be a very different problem. I think you probably need to begin diagnosing the problem by booting in Safe Mode. Here's what HP recommends:

Follow the instructions for "Entering Safe Mode from outside Windows".Re: Laptop Blackout<br /> <br /> T...03439317[/url]

Re: Laptop Blackout

Actually, it worked fine when I pulled the battery and only used AC. That's also what made me suspect the battery.

I'm posting this just to document the issue...the problem is now solved, but others may benefit from what I found.

My Lenovo T430 laptop began to abruptly shut down. There was no warning from Windows 10 Power Management, the screen would just go black and a complete Power ON and reboot was required. The machine would run about 60-80 minutes on battery alone. When plugged in to 120 VAC through the Lenovo power adapter, it would run about 90-100 minutes, even with a fully charged battery. With battery alone, the shutdown would occur at about 70% charge, but when the computer was turned...

Re: VIZIO SV470M orange to white logo, Version 2

Good points...thanks.

I'm using an infrared food thermometer.

Under no load (no back lights, no processor board), all PS components are at the same temperature (about 80F).

With only the backlight as a load, Q706 and FB402 are at 130F. All other components are below 120F.

With backlights and processor board as the load, Q701 and C701 heat to over 140F. C608 and FB601 heat to over 130F.

I'll concentrate on the main processor board first.

Thanks...

This is my first post, so please let me know if I don't follow protocol.

I friend was going to trash this TV, so I decided to try to get it going again. Others on your site have posted a similar problem, so I just called this "Version 2".

When AC power is applied, the Vizio logo is orange, but there's no response to pressing ON/OFF. On the power supply board, there's +5 present but no +12 at the connector to the processor board. I disconnected the power cable to the processor board and used 1K resistors to apply +5 volts to DIM, INV_ON, and ON_OFF. (I did...

Re: New Members - please post your introductions here

I found this site while searching for help in repairing a Visio TV. Although I've worked with computers since 1970s, I really don't do that anymore. My primary interest these days is restoring vintage audio equipment. My primary requirements for choosing something to restore is that it has to sound great and it has to have some other special attribute, such as being an art piece or being the first of its kind. Here are a few of the systems that I've repaired or restored in the last few years:
