Question about Hitachi 53FDX01B 53" Rear Projection Television

2 Answers

I have a 10 year old Hitachi 53FDX01B TV. It was working fine until last night when I noticed that the picture contrast was very dark. I tried to adjust the picture using the TV's on-screen menu to no avail. At present I have perfect sound and barely visible picture. Any clues on what I can do? John

I'm not an expert in rear projection TV's but i know that the 3 CRT tubes have a verry high brilliance output so i would check the power of the brillance circuitry, could it be a defective OVER HEAT SENSOR that monitors the tubes keeping the voltage down ? becaus i know that they ave a verry sophisticated cooling system (some even uses cooling liquid)

Hope it helps!

Dark picture


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.
