Question about RCA HD52W56 52" Rear Projection HDTV

2 Answers

Possible picture tube problem? Delayed picture, blue background, etc.

I bought my HD52W56 last year and all was well until one month before its warranty expiration and the screen started to turn a blue tint when watching a program. At first the screen would switch to the blue tint for a matter of minutes then turn back to normal, but now it is always blue and on screens where there is no picture, you can see lighter blue lines crossing the screen--some curve down/up at one end. Also, when the television is turned on, the screen remains blank only hearing the audio for about 2 minutes before the picture pops on screen. Im leaning towards a bad picture tube, but im no expert. Anyone got an answer to the problem i'd appreciate it. I dont wanna have to spend unnecessary money to have a repair man figure the problem out first then have to pay for him to repair it if its too big of a task for a home-remedy.

My rca hdtv does not have picture only voice

Some possible causes:

No filament voltage to the three tubes.

No high voltage to the tubes.

The set is also prone to bad connections at and around the high voltage transformer.

The picture on my Sony kp57hw40 has bluish hue to it. It is more visible when what you are watching is darker in color or lower in light. I have tried to adjust everything (color, brightness, etc,etc)...

I have first some information for you and then a possible solution.

A lot of these sets had problems with the 3 picture tubes---blue seems to be the most common--if you go to a unused video input and see anything other than Input 1 etc like blue background or even blue curved faint lines do not despair.

There is a fairly easy way to adjust this (not with the remote) I can tell you the procedure and it requires no parts and only moderate skill.

May I assist you here?

I turn on my TV and 10 minutes later it turns off by itself. What is the problem

generally this model shut it self down if anything major. possible reason for a delayed shutdown is bad capacitors. or loose connections. does the picture display any abnormalites before shutdown. does it come right back on when you push power button. any sounds or smells? how long has this been doing this?

I have green and blue arched lines across my screen. how do i fix this

This is one of a group of sets that had bad picture tubes. A lot of them were replaced out of hand when the sets were new--I did dozens of them.

The tubes are no longer available from Sony and only available on a rebuild basis--remove the bad one and send it out for rebuild at about 300 per tube.


HERE IS WHAT I suggest:

With the set at first unplugged you need to remove the entire plastic grill under the front screen. It is secured in one of two ways: either 4 or more screws on the back on either side; it pulls out from the bottom and has tabs that are tucked into slots just under the screen.

The front controls/keyboard are mounted into it so if you get it free you tilt the front grill on its left side to the left; there are wire ties you can release to get more room.

The other way some versions use is there are two hidden screws at the bottom front covered with caps--remove them and lift from bottom and tilt to the left.

The idea here is to try to turn the screen controls for the green and blue (in your case) down.

With the grill out of the way you will find an inspection plate behind it dead center---remove that.


ONE row is marked Focus (Do not touch those) You have to look closely as the controls are black and hard to read--left to right green will be in the middle and red or blue on either side of it.

With the set now turned on go to a unused video input: Locate the blue screen control( tiny letters will be b,g, red with green in the middle---turn the blue down slowly (usually to the left) until any blue lines and or blue background vanish---in your case then repeat with the green SCREEN control until any green curved lines or back ground are gone.

The idea is to lower each screen control until they just vanish--when properly done on the blank input you should only see the "VIDEO 1" ETC in green, with no other color in the background. Do it slowly and it should take less than 1/4 of a turn for this.

If it works you should now have a good black and white picture.

Since these sets have a history of this kind of problem you may only be buying some time---I have done it on dozens of sets and many last more than a year or more without repeat of the problem.

This gives you more life from the set and time to save up to replace it.

Let me know before you attempt this if you have any questions.

If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

RCA D52W20 Too Dark :(

White objects (especially text) on a black background produce a white halo effect around the white lettering. When playing a PS3 game I noticed that the blue color appeared black, as though I had no blue...

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from that includes replacement coolant, photos. instructions, etc.
