RCA HD52W56 52" Rear Projection HDTV - Answered Questions & Fixed issues

HD52W56 D52W56 Check the link and see if the symptoms fit the problem.

There are actually 3 light guns (or as you were told, "light bulbs") in your projection TV, and if one of the guns was failing and making the noise, you only had a one in three chance of fising the problem if you replaced only one "light bulb".

There is no LED on a rear projection television. There are three projection tubes (RED GREEN AND BLUE) and those tubes are mounted in the set and project the image to the mirror and then to the lenticular screen. The issue with brightness could b one of several things. Dust and film accumulate on the tubes and mirror. This causes the image to fade, Also since it has TUBES they age. They are getting hard to find too. The other thing is the adjustments on the set can change over time. There are brightness and contrast settings inside the set that have to be changed and reset after long years of use.

i have seen this before and sorryy to say if unplugging for 5 or more min and that dose not fix it may need to be replaced not many people fix them these days but not impossable

is the line horizontal or vertical ? you have some sort of a deflection problem its either vertical failure or the yoke return circuit on the horizontal has a failure

its setting the screen format . take the factory remote and by using the cursor left or right you can scan the size changes

This is a CRT set. Likely no HV, maybe bad flyback. . Possibly bad capacitors on SMPS area of deflection board too.

May have a pincushion issue is not adjustable, or programming set to one specific size. Sometime this does occur with digital programming.

Your backlight went out. Manual should tell you how to change it

HOW DO YOU FINE TUNE THE FINE TUNING THE PICTHER

Check its speaker first. If found OK, check and replace damaged component/s at its audio output section circuit. If you are not sound in electronics, contact any service technician.

The deflection board needs replacement. You would require the ITC222a chassis deflection board which is available at the following link http://tvrepairworld.com/rca_crt_projection_tvcircuit_boards/rca_rear_projection_tv_deflection_power_boards

That sounds like a convergence issue I would check the setup menu and see if the auto convergence option is stll listed under the setup menu options or hasit disappeared? Let me know and i will assist you with the issue

same deal here..let us know if ya figure it out pls

The model listed is not a Plasma-one fuse on ac line and the other on next board above and to the left of the first one.

The customer one is in the main menu, the advanced one is rather hard to get to; Note if the Convergence option is missing from the main menu you have an issue under the High Voltage transformer or right next to it--this set is well known for this and a "kit" with a diode, cap, and the protect coil is available on the internet.If you go after that resolder all the connections for the Sweep transformer and right around it, bad connections seem to start this kind of problem and no point in replacing parts if you do not also resolder----Good old Lead free solder.

set you have listed has all sorts of convergence problems: look first to see if in menu the convergence option is there--if gone there is a 3 piece kit for that.Also around and under the high voltage transformer this set is known for bad and poor solder connections that cause this problem.see typical photo of the transformer:

TL010 which is the HOT its attached to the heat sink directly in front of the flyback. Unsolder that and see if the fuse stops blowing.

This could be a convergence problem. If you have already tried to adjust convergence through the menu feature on your TV then you may need to replace the convergence chips in your TV and possibly a resistor or two. Take a look at this video to determine what you need...hope this helps you www.youtube.com/watch?v=RGCEM5s5iCMThanks

I HAVE A RED SHADOW RED HUE WHATS WRONG?
