Question about Vizio VX42L 42 in. LCD TV

1 Answer

My television started making a high pitched noise, and will not get a picture when turned back on. I have to unplug to get it to turn off. The remote will turn it on, but will not turn it off. it will not turn off from the button on the side of the tv either. It will power on, but I get nothing but vertical lines across the screen.

TV won't stay turned on, no picture, started making high pitched noise


That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing. In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's You'd need to take to a tv shop and have it checked out. Stargazer
