Question about Hitachi 50FX30B 50" Rear Projection Television

1 Answer

Hitachi 60fx30b I saw on here where someone with a 50fx30b had the same problem as we do. When you push the power button it chirps and flashes and nothing happens. Saw where someone suggested an amplifier? We are trying to locate the actual amplifier to see if this is the problem. Cant find it. I got schematics on the tv and still cant find it. We are at a standstill and could really use some tips on what to do next. How this happened is I turned the tv up entirely too loud and thats when it shut off. Please guide us in the right direction! I appreciate anything anyone can suggest and thanks in advance.

The convergence issue might not affect the TV to the point of not turning ON.
The chirping noise you hear, it means there is a short circuit in the circuitry, possible the HOT or power supply assembly.

Hitachi 43UWX10B 43" Power Light flashes Continuously


I doubt if its the fuse. We just helped a customer with a very similiar problem. Its more likely that the convergence IC have failed and shorted out. When this happens one of the symproms is that the TV will shut down and chirp. Goto www.TvRepairKits.com and click the contact us button. They can provide you with more instructions on how to test if this is the problem.

Power does not come, tried unpluging for 30 sec. still does not turn on 50fx30b mod


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!

Shadows and double vision


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

Chirping noise and flashing front power light.


Theres a short somewhere in the set. Most likly the HOT is shorted or the vertical IC has caused this in the past. In one case I had shorted convergence IC cause this symptom.. This set is solid state and there are no user serviceable parts inside so please call a trained tech to assist you with this problem Good Luck
