Hi,
Since its an old TV so it has weak capacitors in power supply and deflection section and those weak capacitors would be replaced.
If you have electronics knowledge and can do good solder work in part replacement then you can save money by repairing this TV by yourself.
You can download free service manual copy from HERE. Download all Ten Files and unzip it with WinRaR software to get one PDF file of service manual.

Why does my hitachi rear projection tv has double image?


Are the double images different colors, such as red or blue or green? If so, the projection unit is "out of convergence, meaning the images are not superimposed on one another. That requires a convergence generator, also known as a video alignment generator.

Have a 46f500 hitachi projection television. Started out with a blue reversed arc hanging down on upper right. Now images are not focused, and red, blue and green are layered. Double images. I looked...


It is a convergence problem and set uses two of the STK-392-150 CHIPS. Both will have to be replaced and the set adjusted.

for more information let me know if you can solder and your skill levels.

I have a 50fx18b and it wont power up i took the back of the set off it has a red light on but nothing happens when i turn power on


the red light = shutdown led
all the green ones indicate the voltage lines that came up
there is a diagram inside that shows all the leds plus fuse locations. you need to check the fuses with an ohm meter to figure out which one is blow or which voltage doesn't come up. with that info, i can direct you.

Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Flasing red light


The flashing red indicates that either the fileter cover or the lamp cover is not installed correctly. If both are installed properly and secured, the unit will require service.
