Question about RCA R52WH73 Projection Television

1 Answer

Convergence nightmare I have been attempting to fix my free d52w19 (someone gave it to me)- the convergence went bad, so I went on ebay and bought a new convergence board for it... I have since installed the convergence board, and it still looks exactly the same! I CAN access convergence in the service menu, (so I am guessing the fuse by the FBT is good) but when i try to use the remote to adjust everything, the crosshairs dont move, however, it DOES switch when i push OK to change colors or 2 to change positions. when i go into AUTOCONVERGENCE, it will go black, fill the screen with red, and then go back to the CONV menu with no change.... Help me Obi-won, your my only hope! I have a R52WH73 RCA the picture is bowing in the middle like a rainbow the colors are off set from another how or do i fix this. thans

SOURCE: convergence nightmare

I had the same problem, I resoldered the fyback (LL008) and changed the fuse (FL231) had my voltage back, but still no convergence. I read in the service manual that disconnecting BW001 BW002 on the Converagence Amplifier board may remove the load on the Convergence Power Supply. I unpluged the TV did remove it and turned the TV on, let it boot up and run for two minutes or more, then shut it down, waited a few minutes. Unpluged TV and I pluged back in BW001 and BW002 connector back in and turned the TV back on and it was back. Some adjustment and had had a great picture back. If this done do it your out of luck, the Convergence Power Supply and Convergence Amplifer Boards are no longer avialable. Make sure that all the flyback leads are resoldered real good.

RCA D52W19 it kinda looks 3-d i went to the convergence options but it wouldnt let me move the the arrows even though they are way off. and when i tried the auto covergence it went dark a green square...

I woudl not suggest you personally fix this, but can be and easy fix. there are a few fuses around your flyback transformer that blow. there are three of them next to each other. One to all can possibly be blown. just replace these fuses and this should do the trick. will need to do a screen callibration afterwards. If you decide to do the work yourself, MAKE SURE THE TELEVISION is turned OFF! Flybacks can produce and extreme amount of electricity. And experienced tv tech can have you going in about 1/2 hour.

G-D Bless and good luck

If you paid that much for the same repair, man I am sorry. A repair like this should cost no more then a few hundred bucks. OK how much solid state printed circuit board repair experience do you have? If none, NO you should not attempt this repair. If you know someone who does, Great. The convergence amp. IC's need to be replaced. there are two of them. You will need to locate them, order the right ones, as all convergence, Good Luck IC's are not alike, maybe that's why you set went bad again, as cheap or aftermarket type ICs will do this also. Goo luck, If you need more assistance with this, ands can find someone to assist you, or if you can do it yourself, please do not hesitate to get back with me.

Well, misery loves company, so here is my advice, try and get the entire board(s) from the throw away sets, check out TV repair shops they will maybe even give you some of the bits, or even, let you take them out yourself, Just be polite & direct, and I am sure you will prevail. look om Ebay, check local papers, for busted sets, that hopefully won't have same fault as your. These Polaroid sets are a nightmare.. but when they go, they''e OK. If you only paid $50, well, you have a bit of room to move... :)

NO this is a condition known as convergence problems. first question in menu then go to setup and see if the option of convergence is in the menu. is the picture bowed in from the top and bottom. do you have the option of autoconvergence. does it work and how far does it get. there is a common problem with these sets. and may be a simple fix if you can solder a part. so let me know and we will continue to troubleshoot.

It should be hit the unlock button 3 times, open and close the door 3 times, the locks will operate themselves twice. Hit the unlock button on the remote and it should program. you should try a remote from the dealer not from ebay.

Convergence nightmare

If this is a ITC222 chassis then you need to check the fuses that are near the flyback. I would also unsolder all the pins on the flyback and re-solder them as the factory lead free solder tends to crack and cause issues with the convergence. Re-solder it with common 60/40 solder you can pick up from Radio Shack or other places.

Rca d52w19 convergence hell

Did you replace the convergence board or the convergence power supply board? usually one color will be a problem with the convergence board and more than one color means the convergence power supply is the problem. Ebay isnt a good place for boards as you never know if the board is good. You can get the convergence or the convergence power supply boards at the following link along with free shipping and tech support.
