I have sharp LC-37GA9E LCD TV which I am trying to fix for a friend. when turned the green light come on for about 5 seconds and then without doing anything switches to standby, he has no remote with it anymore, but the programme select buttons in the TV itself dont switch it off of standby. Do you know where I can get hold of circuit diagrams to help with fixing it, or do you know if it is a common fault with an easy fix ?

SOURCE: RE: Sharp Aquos LCD TV,

A component is shorting out, and the TV is auto turning itself off for protection. Usually it is a shorted out horizontal output transistor. Only a tech can fix this.

SOURCE: flashing red light

I think this sounds like my problem (need to replace the projector lamp). However, when I hit the "on" button, my SXRD 50" blinks green for about a minute then starts blinking red. Can you confirm the bulb solution? I was very pleased with this sight when my fan malfunctioned. I got the fan in a matter of day's from Sony and it fixed that problem.

Try to maintain the power button depressed. If you get a picture, then it is probably the same problem as this one : http://www.fixya.com/support/t274037-lcd_screen_not_stay
