Red, Blue and green flashing

[Leif]

Hi guys,

I have a LG 42 inch LCD tv that recently stopped working properly. It started flashing red, blue and green when ever it is turned on. I know it's not the cable box because the TV will do this when the cable is turned off.

Any ideas what could be causing this to happen? Is it something that I can replace on my own or will I need to take it to a repair shop?

Thanks,
Leif

Unless you are a service tech, it needs the attention of qualified service personnel.
