Re: Hitachi model # 57UWX20B, IT HAS WASHED OUT VIDEO ON...

The problem with the video from the VCR and Game console only being in the PIP window is likely cured by hitting the swap button (or its equivalent) on the remote control. With the Washed out video on all channels, that could be caused by defective capacitors on the CRT drive board, usually 470uF @ 10-16Volts . It could also be caused by dust buildup on the Lenses, and if the set was used in a room where people smoked, the mirror probably has a film of nicotene on it as well. I don't know what you mean by a vertical problem as well. If it involves retrace lines at the top and a shortening at the top and bottom, then I would suspect capacitors in the vertical circuit there as well. If it is a vertical jitter that you are experiencing, I would suspect bad solder connections in that same area.

Signal Problem


When the sound is working and the picture is not it indicates the main power supplies are working but the picture supply is not. The picture supply that powers the projection tubes is a high voltage generator and is very expensive to repair. Not even most tv techs now how to troubleshoot them. So, I cannot recommend you repair it yourself unless you are a trained high voltage tech.

The cost of repair - my wild guess - would be around $300. However, the real cost can only be determined by someone who can make an accurate diagnosis - which will require a hands-on approach the problem.

If you have any other problem please ask me..

Washed out video on all channels/power lights blinks no power


You could probably do the replacement by yourself.

First, go to the owners manual and make sure you have gone through the convergence set up. See page 45 of the manual. When pushing the magic focus button be sure that the set does inaugurate the convergence routine.

Your model has hundreds of parts listed at the site; I did not search for the STKs but what you can do is find the part number on the case of the convergence ICs and search for it. They cost around $30 to $50 each and there are two of them of the same part number (usually). They must be mounted with great care.

Why would this happen again? Could be a poor design, could be poor mounting of the stks and heat transfer was not adequate, could be out of spec parts, etc.

Expect to take a couple of hours at least to do the replacements.

CAVEAT: We cannot be sure it is defective STKs, so do all the checking and testing you can to pursuade you that they are the real culprit - again.

If you go to and do a word search on "stk" you will find many interesting comments by others about replacing them and various other convergence comments.

Also, if you go to and look down the Hitachi list you will see a convergence file that may be helpful in doing the convergence...... It is for an older set, but I believe the procedure is about the same for your model. (This is in the manual setting area, not the Magic Focus automatic procedure).

If anything herein is confusing, please ask more questions. Good Luck with the repair.

My rca has no picture the screen has a snowy picture is if it was on the wrong channel through my cable box.

More information would help. What are you running the signal into the TV with? Coax? Separate video/audio? To test the set if you have a vcr hooked up or available to hook up, input it into the tuner input and play a tape. Set the tv to either channel 3 or 4 (whichever channel the output of the vcr is set for, this can be determined by checking the menu or a switch on the back if it is an older vcr). If your TV is ok you should be able to see the tape which is playing. If not, and you still have snow you probably need a new tuner in the set. Let me know if you need more help.

Pip working but main screen not.. model pcl541r

If the main channel input is not giving you a picture, you need the tuner checked out or replaced. a good indicator is when you select a channel with the remote you will get just snow(sometimes followed by static in the audio)you do get the picture in picture thru the auxiliary inputs on the tv because they go directly into the audio and video drivers and bypass the RF circuitry. One way of making sure that the tuner is the problem is by hooking up the coaxial out of a vcr or dvd player to the main in or cable in of the tv and selecting channel 3 on the tv and then try a tape or a disc, if you get a picture then suspect something crossed in your installation between pip and main in of your tv set.please your feedback if i answered your question.thanks!

Hitachi 57uwx20b

First of all there is no light engine inside your set. Your model is CRT based. Can you better describe what you mean by the green only working occasionally? What exactly is the picture doing? Also, please confirm that your model is: 57UWX20B.

My big screen tv show snow on all channels.


if you see only snow on the regular screen, might as well check the connecting antenna at the back since you mean all snow on all channels.

hope this helps.

Picture in picture

i am not familiar with this model, but on most sets you will have a button on the remote to activate pip, when active you should be able to adjust channels on the small display with the remote and cycle through inputs. depending on the tv you will either have 2 inputs for your cable/sat/tv feed, or will have 1 with a dual tuner.
check the connections in the back for a second cable input, or hook up a dvd/vcr/game console/etc to test the pip.
start dvd or tape playing, press pip button to display the mini-screen, then use the tv/vcr or input button to cycle through the modes and see if one pops up. most tvs that have pip will also have a swap button on the remote, it may be labeled with text, or it may just look like one screen overlaying another, press that one to swap between displays.

hope this helps,
