Proscan 37LB30QD - No Power [Repair]

A friend just came to me with this TV complaining of issue with not powering and/or instantly powering off. Time of ownership about 2 years. I found that all three of the 470uF 16v capacitors on the power board to be blown. Because all three of this type were shot I replaced them with 1000uF. A higher voltage capacitor can be used if another 16v is not available. I believe Radio Shack only carries 35v. A cheap $5 fix for anyone else experiencing a similar issue and should apply to similar models of this TV. Repair time < 1 hr. Be mindful not to loose the four small brackets around the edge of the LCD when removing the rear cover.

Toshiba satellite turns on but power light blinks and screen is blank


Start as basic as you can, remove everything you can, RAM, HDD, modem (if equipped), WiFi card, optical drive, etc. It should beep when powered up, complaining about missing RAM. Install RAM and see if you can get it to POST. If so, install 1 item at a time until it stops working. Bad part found.

If it doesn't complain about the ram, it's probably a bad system board. If it does complain, but doesn't post with the RAM in, it could be still be a bad stick of RAM or a bad RAM socket on the board, try one at a time, and in each of the sockets.

Problems with Skype connections


We've been using Skype for three years and slowly we have seen it deteriorate in quality and service.
The problem you describe sounds like a bandwidth issue at Skype. You will see the same hting happen on video conferencing if you use it as well. Nothing really you can do other than complain to Skype. If enough of us complain, maybe they will start working on quality again.

how to turn off tv-out


This sounds like a software glitch, I would recommend reinstalling the Power DVD. I use Power DVD and have never had this problem. If it persist, then you can disable the tv out from the device manager.
