Question about Hitachi 50UX57B 50" Rear Projection Television

Open Question

Hitachi Ultravision Projection TV

I've got a 50in Hitachi Big Screen about 10 years old. Recently the picture went out. Sound works fine, pressing menu button and menu shows up crystal clear, however no picture from cable or dvd player. I can hear everything, but can see nothing. Please Help.

check the solder around the area of the vertical IC. solder is either cracked or else cold. Cold solder appears as dull. Resolder anything that isnt shiny.

SOURCE: Rear projection HD Hitachi Ultravision always has greenish tint

This is what you're going to do, Turn on the Tv and go to the service manual, if the green tint is still there, you have a defective dmd board, but if it's no there, then you have an issue with your video board

I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

if the power button is blicking red then most likely ur lamp needs to be replaced. they dont come cheap but its an easy fix ...try ebay for the part ...and make sure u get the correct seze and watt for that specific tv ....on a side note...if u replace the bulb yourself....wear latex gloves and DO NOT touch the bulb. the oils on your skin will magnify the light and can cause that bulb to explode or pop and then u will be right back at squareone

Probably a 'cold or detatched' solder joint on a component on that perticular circuit board you are 'wedging' with a plastic rod.
