20 Most Recent Hitachi 50FX30B 50" Rear Projection Television Questions & Answers

If hitting the TV sometimes corrects the problem then usually there are some bad solder connections. As the sets heat up and cool down the pc boards slightly expand and contract, where a component leg sticks through the board and is soldered on the other side a small crack will develop around the solder connection. Sometimes they are easy to see, sometimes very difficult. One way to narrow down where the bad connection is, being very careful because of dangerous voltages, using something non conductive lightly tap different parts of the pc boards to see what area is most sensitive, then you would need to unplug the set and get to the bottom of that board and look for the bad connections.

You can most likely connect your computer to your TV, but it depends on what kind of connections your computer has and what inputs your TV has. The best solution would be if your computer has an HDMI port and your TV also has one. If your computer doesn't have one but it has a DVI connecter, that is the second best solution because you can just get a DVI to HDMI adaptor. The last solution is the worst case scenario because it is analog. If your computer and TV both have VGA (the blue trapezoid plug) you can just get a VGA cable and connect the two like that. The reason that is the worst is because the quality is not that good, but in the end it will work. If you want sound, you will need a cable unless you have an HDMI port on your computer and TV. If you don't just go to the store and get a 3.5 mm headphone jack to RCA connectors and plug that into your TV.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Projection sets have two very common problems.

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

Its possiable that you may have poor solder connections where our STK ICs are resolder them and transistors they are big black ICs will have STK392-110 on them. I would First start out with soldering everything on convergence Board.

Hitachi 50FX30B... | Answered on Sep 24, 2009

sounds to me like you either have a blown fuse, or a power supply problem. I would take it to a reputable service center that won't rip you off, and see if they can repair it for a reasonable price.

Good Luck!
