RCA R52WH73 Projection Television - Answered Questions & Fixed issues

Lowest screen setting for ANY other screen can be an awlful default size. So if two or more screens to watch the computer are connected then this can happen.

Hello my name is willie. I see this problem alot on these units at the shop. And from what you describe. THis might be the very common problem with the fl231 fuse. this is a very fine fuse that blows due to bad solder connections. If u can solder and get this very special fuse then this is a very easy simple repair. But the first question you can answer to determine if this is true. is that when you go into customer menu then setup do you have a convergence option in the menu if you do not it is definatley this fuse. if you do then it will be something else like convergence power board. let me know if it is and i will see if i can talk you through the repair.

Thats a common issue with that chassis ITC222A which is always caused by the small signal board needing replacement. You should be able to get the small signal board from www.tvrepairworld.com

the Tv does not have a convergence menu like other models do .I.E. Toshiba, Panasonic ECT...If your having a Convergence problem then you have a Fuse gone out . you may have another problem too, but I'm betting tis just a Fuse and you can get a repair kit at WWW.Tvrepairkits.com they are affordable and have great support in helping you fix your tv

The link below may help you. It is for a similar television and may cover yours also. http://www.manualowl.com/m/RCA/R52WH74/Manual/229723

check in the menue for sound options, make sure the internal amplifier box is 'checked'

Somehow this got posted in the TV area here, Look to see where the leak is coming from and better yet have a mechanic take a look, oil leaks can either be a minor repair or a major repair depending on where it is coming from.

shutdown issue and see previous answers.

see previous answers that this is a shutdown issue.

See previous answer that this is a shutdown issue---

Set has a "shutdown" circuit and will do this if a problem exists.Not many customer service able parts here--common issues include bad solder connections are found around high voltage transformer--if you are not able to look for this consider a tech looking at it for you.

replacing the deflection board will solve that issue about 95% of the time. You need the ITC222A deflection board PSB260 which you can get from www.tvrepairworld.com listed under the RCA Projection circuit boards. It comes with installation instructions.

The set indicated is prone to this kind of trouble.If in the menu you do not see the convergence (your problem) adjustment mode listed--there is a 3 part kit for that---a part opens and the set detects that and removes that item from the main menu.This set is also prone to bad solder connections at the high voltage transformer which cause both the 3 part kit problem and other convergence troubles.Have to get at the board with the high voltage transformer and look for the bad connections---I attach a photo of the transformer so you know what it looks like and will be able to locate it in the set.Let me know if you need further help.SD TECH NOTE THE PINS ON THE BOTTOM-that is where you want to look for broken or poor solder connections on the bottom of the board.

Yes it has a built in digital tuner.

I think from memory you are likely to find it is a resistor and if burnt to a crisp the high voltage splitter block up front is bad.

replace the deflection board your model uses the PSB260 deflection board available from www.tvrepairworld.com

Hi,

Hope this solves your problem. Thanks for using FixYa

I can only give you some general advice without seeing what you have (could you perhaps post a photo or two on Facebook?). Someone with a service manual could tell you more if you provide the part identifier printed on the board (for example, a resistor might have a label next to it or under such as "R357", while a transistor could be "Q241").The part that is overheating may be the problem, but more often it is getting hot because another part has failed and is causing too much current to go through the overheating part.If your set has the typical CRT rear projection TV layout, the board in question is a high-frequency switching power supply. The noise you hear may be from an overloaded transformer. A very common failure mode in these power supplies is a shorted diode on the secondary side of the transformer (the side away from the power input). This will cause an overload on the primary side and put it in some form of current limiting mode (in many designs it just blows a fuse, but in some current is limited by electronic protective shutdown circuits).Finding a shorted diode is not difficult if you know how to use an ohmmeter and can identify a diode (the board marker will be "Dnnn"). A good diode will have a large resistance or read open if the test leads are connected in one direction, and have a smaller resistance in the other. A bad diode will read close to zero resistance in either direction. CAUTION: resistance tests must be made only with the set unplugged! Attempting to read resistance on a live set can cause severe damage to the ohmmeter, and could blow up the power supply, to say nothing of personal hazard from the high voltages present.Here are a couple of typical diode packages:.This part is usually mounted on the board, sometimes on extended leads so it has some airspace between it and the board for cooler operation. The image shown is about size of the largest examples of the DO series package type. Note that there is a band painted on one end of the diode. If you connect the minus lead of the ohmmeter to this end and the plus lead to the other end, you should get the lower resistance reading mentioned previously.The TO-220 package is shown about the actual size. It is also used for transistors, voltage regulators and other power integrated circuits, and (rarely) resistors. The center lead is often bent outwards to fit a triangle hole pattern in the board, and the tab is fastened to a metal heat radiator of some sort. Use the board marking to identify the part (if it doesn't start with "D" it isn't a diode), or look up the part type number online (printed on the front of the package). Often there will be two diodes in the package sharing a common connection to the center lead. The center lead is usually equivalent to the banded end in the DO-type diodes. Note that transistors also often fail by shorting out. Once in a while the failure is obvious - the plastic will be cracked, burned, or even have a crater blown out of it.

the convergence power board PSB260 will need replacement. You can get the convergence power board from www.tvrepairworld.com

Check to see if the auto convergence feature is still listed under the setup menu options or has it disappeared from the setup menu options. Let me know and I will assist you with what to do to repair the issue based on if the feature is still listed there or not.
