Question about Hitachi 51F710 Rear Projection Television
My Hitachi 51F710a tv is dark. I've adjusted the color,contrast,brightness...everything. The picture is still extremely dark, I cant watch anything. Any clues?
Just a guess,under the power button, inside the the flip[ down cover is a light dimmer,you can turn this on and off,in advanced settings under video,a flash light will trigger the sensor to see if it works the dimmer,if not it could be that circuit or your power supply needs work,I hope this helps!

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

toni, you`ll need a tv tech for this problem, spark gaps need to be cleaned, crt sockets need to be cleaned and crt pins on all 3 crt`s need to be sanded, this is a common issue with this model set, good luck, BMW Rider

Could be the blue CRT shorting out. I had the same problem but with red. Eventually it shorted out completely. If it is only 2.5 month old it should still be under warranty and they will fix it.
