Big Screen rear projection TV picture not showing

Had a problem with my Hitachi Big screen projection TV, TV would turn on but had no picture, didnt matter what input it was on, the DVD and Playstation had no picture either, read that there is a known corrosion issue with the sockets, all that you need to do is unplug and plug everything back in several times in a row to break through the corrosion to allow for a new and clean connection.

blu screen


Your on the wrong input! Press the input button and turn on all your tv viewing receivers such as DVD player. FTC or dish network box. Or cable box. And press input till you find picture! The blue screen is an input with no video or audio source being sent To it!

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays. when i change input to one not being used the screen used to be straight black now blank input screen not being used is red.recently hooked up moxi box but even with nothing hooked up to any inputs all input screens are red


Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

picture has a blue shadow


Hi,
Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
