Re: Envision TFT1780

I purchased 4 of this model new at the same time 5 years ago. Now one of them will not light up at all.

I noticed that the power supply LED was blinking. So I swapped it out for one of the other 3 good ones. Same problem. My local PC parts supply store believes it might be the illuminating tube, which he says only costs $10 to swap out.

Are there other threads which review repair options for this monitor? Thanks.
