I have a RCA HDTV Model #R52WH74 Serial #G385c1080
This set is known for low grade Chinese capacitors in the power supply, most likely if you remove the back you will see some that are bulged at the top and bad, you have 2 choices if you want to fix it yourself, purchase new caps and solder them in or replace the power board, caps are quite cheap if you can solder and have the equipment

Hi if the adjustment is not in (ROM) read only memory, it might lose it's memory & reset to normal ::::::::TURN POWER OFF AT THE POWER POINT FOR 5 MINUTES & HOPE IT RESETS.. cheers
Im trying to change the
Without the OEM remote you can't access that video menu to change this aspect ratio. Have you looked on eBay for an OEM?
I adjusted my convergence on my hdtv, but there is
I have worked with some of these in the past that have lost the convergence memory. What a pain to reset. You would have to go to the factory settings with a code. This would allow a complete grid reset of convergence. I would NOT recommend that someone without electronic experience try this alone. This procedure is recommended only for service professionals.
No signal on dtv do I need a DTV antenna
You have an awesome antenna - every one should have one like it!
An antenna that used to work with the older analog signals will work with the digital ones. What you have to remember is that analog systems though subject to ghosting, were brutes signal wise ala the metal on older cars. Digital signals are frail and even tree leaves in between the antenna and transmitter can have adverse effect on signal received.
If the sound is weak on your set that is a function of your sets audio section. Somewhere you are losing gain and/or amplification. If you have an audio output you might consider hooking that up to one of the audio inputs on audio receiver. It will work fine and that is what I did with my unit.
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Green lite keeps going off
you have the ITC222A chassis TV so it only has the one power light does it come on briefly three times then go out and stay out or does it come on one time then goes out and stays out? Let me know and will assist you with the issue.
Power light blinks 3 times
Thats caused by issues on the deflection board. It can be the power caps CP150, CP120 and CP114 or it could also be the Flyback and HOT tarnsistor or several other items all located on the deflection board. Often its easiest to just replace the deflection board on that model. You can get the deflection board from www.tvcircuitboards.com
I have a rca projection 52 inch 3 lenses power comes on but picture not .... is there bulb or some thing i need to find and replace or fuse some where
there are a few things that can cause this symptom but we need to go back and regroup .
let's go at this from a technical stand point .
when you plug the unit in and turn it on what do you see the led's in the area of the power button and pay close attention to the blinks if there are any . then we can try to get you on the right track .
also id guess you already have the back of the set off ?
if so on the large board on your left side looking at it from the rear of the unit . there are some caps that we should look at cp150 cp130 cp120 if i remember correctly . what your looking for is the bulged cap that some many hit on and true its a problem but if it hadn't been for caps failing they may never have fixed them .
one word of caution is not to push the power button excessive at this point if there is a loss of deflection you may well damage one of the crt's or picture tubes this unit has a red crt blue and green and they provide the screen lighting and video you see .
with you behind the set perhaps you could have some one push the power button and listen to that high voltage transformer on the left side board it has a red wire coming off of it . and be cautious there is possible shock hazard there .
and if you have access to the caps i would change those caps right off the start as they are most likley defective as well as other possibility then let me know what you find and il see what i can do to assist you
I have a rca HD52W59 and I am getting a double image of red and green tried the covergence setting does not help
Make sure your convergence is working or at least going thru the motions faster than normal . what was causing that to happen to my tv was that i had my component stereo speakers surrounding my tv on both sides and directly on top of the tv.what you have to do is take all speakers away from the tv unplug and hold the power button for 30 sec to totally discharge power from your tv let it sit unplugged overnight or least 4hrs .after that plug it in and adjust with convergence menu.
