Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

I have a 50 inch hitachi ultravision that has no picture or sound but power light is on

I have a 50 inch hitachi ultravision projection screen tv model # 50ux53k anyway the picture was jumping at first for awhile and a few months after that started happening i took off the back and found that if i put pressure on the circuit board it would stop jumping.so i wedged a plastic rod to keep the pressure and it worked fine for a few months and then the picture began to squish to the center (top to bottom) so i then took the back off again to find that the plastic rod fell down so i replaced it and it work for a week or so. then the picture went blank no picture or sound and the power button is on. can someone help.

When I power on tv, seems like it is turning on and off continuously. No video, popping noise. Lamps go on and off also. Thanks in advance

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

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.

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

Likely the lamp in the set has failed here which does make sense if the picture was dim before---a lot of lamps just before failing all the way dim down.

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
