Tip & How-To about Philips 37MF321D 37 in. LCD Television

Power Light Blink

I had a Magnavox 37MF321D that would blink the power light and the screen would flash but it would not power on or off. I show in the video below how I found IC 7003 bad and how to change it. I also show how I got a vertical line problem fixed. Below I added a link for the IC 7003 I ordered from Mouser Electronics. L5973D STMicroelectronics Mouser
