Looking for a schematic diagram of circuit board for rca hdtv model d52w15. serial: e454c304aw please help anyone thanks

I don't have a schematic for that model but here is a link to the SHOPJIMMY parts supply page for that model which will show you images of what all the different circuit boards inside that set look like including the POWER SUPPLY board.

Just use your mouse to click on the link, which is the underlined and blue highlighted section of text just above.


This will open a new web browser page automatically for you and allow you to view the information at the website indicated.


Once you get to that page just click on any of the part numbers listed there to see an enlarged image of that particular circuit board as well as the replacement cost for it. This should at least help you identify all the components inside so you know hat you are looking at.


I hope that was a little helpful to you anyway.


Good luck and take care.

Replace you flyback transformer and Horizontal Output Transistor

well i can't get the schematic free
sorry i just don't have that one yet
, but there are some tips and a schematic for sale

here is the tip area , you can also ask here , just don't know how long before they get to you
but here is one of the tips for your tv http://www.freelists.org/archives/techassist/12-2005/msg00321.html

here is where you can buy your chassis schematic

that model is famous for having bad flybacks. fortunately they arent exspensive and there easy to replace. you can get a new replacement at the following link for less than 50 bucks and they give free instructions on how to install it properly.

yes i do believe this tuner will work even with the missing pins...i have replace these here at the shop and found the pins unused...I would go ahead and try it... i dont think there will be any problem let me know if it works

i have noticed that the new tuners are missing a few pins. i believe that it will work. what is the exact make and model of the set there is a tiny printing of the model above the model # i has d52w15...yx....something. you need this to cross reference the tuner. let me know and i will cross ref it

My SONY TV Model : KV-XJ29M50. LED will blink/flash twice right after power turn on and cannot display picture.

Blue CRT has shorts that causing the set to go into protective shutdown.

Two boards govern this circuit . 1) convergence power supply board # 271860 2) convergence amplifer # 271861 . In most cases amp board is your problem . You might want to check the amp board for loose connections on it .Most of the times its the cable sockets on the borad have loose pins . This the board that has the metal heat sinks in a row of about nine of them on the board . Good luck
