Question about Hitachi 51SWX20B 51" Rear Projection Television

1 Answer

Hitachi 51SWX20B projection TV has no picture or sound

The Remote doesnot turn on or off the TV anymore. I had to do it via TV panel. But in any case there is no picture or sound. I tried many simple troubleshooting like switching off and on many times, changing the power from surge protector to wall outlet, waiting before turning on. But nothing has worked. What can I do? Please help. If it needs change of fuse, do i have to call technician or is it self serviceable?

First lets check the remote to see if its working , with a digital camera facing the front end of remote (where THE EYE is) look thru the camera screen while pressing any button from remote , you should be able to see FLASHING LIGHT coming from the remote. SECOND about your TV , better off to have unit check by an authorized tech . hope this helps

My Model TV # is 51swx20B. Two days ago the picture started having a lot of green in it and no blue. What is the repair needed.


Do adjustments on focus block. Will have to open front panel access door, focus block blue will be on left, green will be on top. Top screen bottom focus. Turn clockwise to increase, counter clockwise to decrease brightness. Turn the color all the way down on menu where it's pure black and white and make adjustments for perfect black and white picture, then when you adjust color, it will be perfect.

I used Hitachi TV convergence repair kit to fix tv


Check the Components received are compatible with manufacturers numbers or if they are generic the voltage,ohmage,ampage and resistance must be almost the same.

Using a multimeter take out and test each individual components.They could have sent you faulty parts.

Ensure you follow the instructions very carefully when soldering them onto the board.

Hope this helps you

The convergence going bad again on my Hitachi 51swx20b


Sounds like loose solder on the chips. Either that or they are failing. You can save money next time by doing it yourself with a kit from www.TvRepairKits.com

No Picture No Sound


were the colors looking 3D before the set shut down? If so chances are its the convergence amp ICs and thats what has shut your set down. Let me know if you need anymore info.
