Where is the flybac located in a rca hd52w59


Hello
Flyback transformer other wise called Line output transformer {LOT} is actually a step up transformer, which supplies extra high tension voltages to the guns. It can be locatee on the main printed circuit board. 2_7_2012_5_19_59_pm.jpgJust see the different views of the main board of your RCA TV. You can see the flyback transformer at the left top corner, look like a large black componen; with a ferrite "U" type core goes though it. It is the LOT. Line Output Transformer, otheriwse called as Flyback Transofrmer. OK.

The model indicated does NOT use a chip for convergence output; the convergence circuit is divided across three circuit boards.

Does the convergence option appear in the menu or NOT?

Check circuit board for bulging at the top capacitors. The board you are looking for is the one with the flyback transformer. This transformer is the one with a thick red wire going to the top of it. Replace all bulging capacitors. Capacitors are the ones that look like little cans. While you are there resolder the bottom solder points on the flyback transformer. This should work, because it worked for me.

THE TV WENT POP, SPARKED AND WENT OFF COULD IT BE THE BULBS AND IF SO WHAT DO THEY COST ABOUT


the flyback or CL031 are the usual causes with that chassis doing that. Usually CL031 will burn a hole through the deflection board its located about two inches in front of the Flyback transformer.

I plug it in and it arks from flyback to board no cracks in flyback this started after i clean a connection on the board because it would turn off and on when hit or walked by


Sounds like you need to resolder the connections on the flyback transformer. You also need to insulate the area of the board that it is arcing to, a piece of Insulating tape or Mylar film, will help, this is happening because an Over voltage situation is breaking down to chassis. Be careful though even though the FB looks OK, often thery are NOT it only takes a pin hole for this to happen..

Have a Hitachi 53sdx89BA Rear Projection TV. Turn on TV and red power light illuminates. No picture, but have sound. Check PC board in back and red led is flashing and green leds are lit. It was working...


Discharged Flyback Transformer. Removed main pc board from bottom of TV and flipped over, no apparent damaged components or blown board traces were found. Noticed a lot of flux in various areas on the board that seemed unusual (maybe TV was worked on before as I bought a showroom demo at Circuit City). Used a plastic screwdriver to remove all flux between connections on ICs, Transformers, Flyback Transformer, and various other components. Cleaned all debris, dust and crud accumulation (TV is over 10 years old and there was alot around the Flyback Transformer) from both sides of board using a lightweight paint brush.
Used a magnifying glass to check all solder joints for possible cold solders and found none. Did the same for Power Supply Board. Checked various ICs and Power Transistors for opens or shorts (in machine) and they seemed fine. Reinstalled boards, said a few Hail Mary's and fired it up.

The protector Led no longer flashed under power and lo and behold I got picture and sound!

I cleaned the lens on the projectors (again 10 years of dust accumulation) did a magic focus adjustment and it works fine!

After reading other fixes, I fully expected it to die after 10 minutes so I left it on all day and against all odds it still works.

What was the fix......Dirt buildup on and around Flyback and other components,,,,,,Flux conducting electricity between contacts on Flyback and other components.....or oxidation on connectors between Power Supply and Main Board.....I don't know.... all I know is that for the moment I saved around $ 300 - 400 in repair bills by doing it myself.

Circuit board needs replaced


I replaced mine, it's called the Deflector board. Some people call it the flyback board after the flyback transformer that is located on it. I found one on Ebay for 25 bucks a while back, so good luck. Troll ebay or find someone that is giving their tv away on craigslist because the convergence or a bulb is bad. Don't base it just on your specific model of TV though because many of them share this common board.


Try part #271827. That was the part number of the board I won on Ebay.

The flyback transformer is super high voltage. Have it checked out by a shop, don't go near it. TV's can hold a charge for days.

This part is called the flyback transformer and is part # 239111 at a cost of $68.99 from tritronicsinc.com. You can replace the transformer. It sounds like it developed a short internally. There may be other parts that were effected as well. If you are not comfortable working inside hte set, expect a service call to run about $100 for parts plus hte local labor rate.
