Picture on Samsung TXL2791F gets smaller after a few minuets


The horizontal output transistor that drives the flyback transformer overheats now. There might be other reasons too for this fault. If the flyback transformer has any internal winding short, this transistor will overheat.
Just replace the horizontal output transistor. Check its heat. If the newly replaced transistor too overheats, replace the flyback transformer.

I have the RCA 52 in hd 5267 can someone tell me where the flyback transformer is located. I see where dave1645 said how to fix the problem of the 3 dimension colors i just dont know heer that stuff is...


Remove the Back panel, Then look to the far left lower board you will see a large transformer with a thick red wire coming out of the top of it. Thats the Flyback. There are three small brown rectanges just to the right side of the flyback. The center one is FL231. When that fuse blows your convergence will go out of alignment and the option will disappear from the menu.

The convergance menue is gone. I need to adjust the convergance badly but it is no longer in the menu


You need to resolder the flyback transformer and replace fuse FL221 off pin 11 of the flyback transformer. The convergence power supply is not coming on so system control thinks a convergence circuit is not installed.

There is a hissing noise in back of tv and picture goes on and off zenith d36d51


Hissing noise and picture on and off means faulty flyback transformer, it has a small crack and voltage is leaking out, replace the flyback, if tv still not working replace horizontal output transistor (broken flyback could blow the transistor).

Flyback transformer and horizontal output transistor change out


There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

Still not working after replacing the capacitors


Hi Jim, The problems I have found on these similiar sets are power supply problems and Horizontal transformer ( Flyback transformer ). The clicking I assume you are hearing may be the flyback transformer ( thats the big black transformer with the big red wire along with a couple of other wire coming off it ). The horizontal transistor is sometime the cause of this also, so if you have a transistor, or diode checker, check the horizontal transistor first. If the transistor is bad, it may be an indicatioon the transformer is also bad ( one will burn the other out sometimes). I hope this helps in some matter. Good Luck

RCA F27669 27"


The F27669 uses the CTC203 series chassis. The most common cause of that symptom is a shorted horizontal output transistor, caused by a cracked solder joint on a small coil connected to that transistor's base. When this happens, the main B+ supply is shorted to ground so the power supply squeels. Every once in a while I also see the horizontal output transistor shorted due to a shorted flyback (high voltage) transformer. A good tech will replace the horizontal output transistor, resolder the coil and drive transformer, test the flyback (replacing it if necessary) and your set will be back to perfect.

Lamp issues


No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
