It very well could be the flyback unit around 70.00 for part!

HITACHI 57F710S - no red in picture. Magic Focus shows Red, Blue and Green perfectly. But when "Magic Focus" is done, picture doesn't have red in it. Help!


Projection sets have two very common problems listed below. bb0cf99.pngYou can see some more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Our Hitachi tv turns on okay but the picture on comes in for 2-3 seconds and then the screen goes black. Last night the tv work just fine but this problem started today as I turned the tv on to watch...


I don't know what model you have,but... I have a 50v715 and it was doing the same thing and it turned out to be the lamp. So if you have not replaced the lamp in a while then it could just be it time. Hope this is helpful.

this could be your flyback (one of the most common problems) the part is cheap but the pro you need to put it in will not be!

Sounds like a video board problem. May also be the convergence board. You might get some freeze spray ( a component cooler that comes in a spray can ) and while the set is on, spray the boards and see if the problem temperarly corrects. This is to isolate the problem. Once the problem is isolated, you can change the bad component. Good Luck
