    How hard is it to replace, where can i get one and how much would it cost. thanks

    gazer... my electronic background is limited... Will the transistor be a direct replacement.. meaning color for color so i can identify it? the transformer will probably look the same...Right? I have a friend with steady hands... sounds easy enough.. and it sounds like your pretty confident that this is the problem.. i think its worth a try. THANKS!!!

    where on the circuit board is the transistor... all of them have #'s, none are described as the horizontal output one. I dont have a wiring digram. Most have a 4 digit code next to them. THANKS AGAIN

    I replaced the HOT and the fly-back transformer using generic parts. My TV now turns on but has horizontal lines across the screen...Turning the adjusting screw on the fly-back transformer counter clockwise makes it come in the best, and clockwise loses the picture completely. Ends up going to a blue screen. Any suggestion???

A high pitched chirp is a sign that you have a short on the load of your power supply. I just finished repairing one of these sets and it had a shorted horizontal output transistor and a bad flyback transformer.

    Hello,Hack!
    The flyback for this TV is available from:
    Surburban Electronic,Suitland,Md, 20746
    Phone: 1-800-341-5353
    Part# GEN257805 @ 18.95
    Horizontal Output transistor: 2SC5148 @ 1.98.

    If you're experienced at changing parts this is not too difficult to do.FIRST, MAKE SURE YOU HAVE IT UNPLUGGED!!!!!
    You have to remove the main circuit board and use solder wick to remove these parts.
    You need to be careful when unhooking the big red wire going into the top of the picture tube
    since it may have a charge stored in it. Use a jumper cable with a screw driver hooked to one end. Clip one end of the jumper to the gound wire on the outside of the tube and push the blade of the screw driver under the rubber cup where the red lead goes into the tube. If any charge is there you'll hear a "snap". This should discharge any voltage stored up in the tube.
    There are several cables connected to the circuit board. You need to remember where they plug. You might want to draw a picture of where
    they plug to the circuit board.
    Once you've got everything installed,double check all the cables that you unhooked. Make sure all grounds are connected. This is very important.
    When you're sure everything is connected correctly you may power up the set. If you don't hear the squeal like you did before, then it'll probably come on. If the screen is dark you need to turn up the screen control which is located on the transformer you just replaced. It's the bottom one. The top one is the focus control. You need to watch the screen while making these adjustments.
    This FLYBACK is a generic. It seems that it is difficult to get one from RCA. I think they want us to just throw their sets away and buy a new one.

    I hope this information will help you!
    Good luck and be careful!

    Hello!
    The transformer is a different color but will physically fit right into the holes in the circuit board. All connections are the same.
    The transistor is identical to the original transistor.It is a black plastic case transistor with just 3 leads to connect. Like most transistors.The 2SC5148 is written right on the transistor.
    Good luck !

    Hello,Hack !
    Sorry I didn't tell you where the transistor is located.
    I forget the reference number but it is located near the flyback transformer. It is on about 2" X 2 1/2" piece of aluminum which stands up and the transistor is held to the aluminum by a black flat spring clip. YOU can see the number when you remove the spring clip. You un-hook one end of this clip and swing it out of the way or remove it to release the transistor. It would be a good idea to put a little heat sink compound between the transistor and aluminum to make a good thermal connection between the transistor and the aluminum heat sink.When you put it back. It is important to clamp the transistor to the aluminum (heat sink) to keep the transistor from getting too hot and destroying itself.The three leads go through the circuit board. You turn over the board to use solder wick to remove the solder from the leads.
    Also there is a black "L" shaped plastic bar which clips to the top of the fly back to help stabilize it on the circuit board. You need to remove this to get the flyback off the board.Of course you un-solder the flyback's leads first.
    At each end of this "bar" is a twist lock sticking up through it. Just use a pair of pliers to untwist the tabs at each end so that this 'bar' can be pulled up from the fly back and circuit board.
    If I can help you in any way, let me know!

sounds like a shorted horizontal output transistor probably caused by the high voltage transformer or hot. it is most likely fixable but it will be costly.

RCA TV dead


If this is a crt type tv. This could be attributed to a faulty high voltage circuit. A defective horizontal output transistor or the flyback. Or better to check some minor component with regards to flyback like diodes.

RCA TV Model F32444 Will not power on


The noise you are hearing is probably the degauss (it demagnetises the screen every startup). The most likely problem is the power supply. Do a replacement of all the caps on the powersupply board and it will likely fix your problem. Because it still has power to the degauss coils it hasn't blown the fuse. Power supply not starting like that is usually caused by a small electrolytic capacitor near the heatsink on the mains side of the powersupply. They can be replaced for about 10 cents.
Hope this helps

TV does not turn on. When plugged into an outlet makes a high pitch noise.


Your problem is a shorted horizontal output transistor C5148 located behind the highvoltage transformer on a heat sink with a clip over it and you can't see the number unless you remove the clip Has to be unsolded and solder in new. Also the highvoltage transformer must be replaced This is the big part with the large red wire coming out and going to the top of the picture tube. Must be unsoldered and replaced with original RCA .....do not get a replacement It has several connections plus three wires to connect to it and I recommend using desoldering brad can get at Radio Shack 5 foot roll. Well as you can see it gets pretty involved. You can't get the parts from most distributors unless you have a business. If he tackles it and has a distributor the parts would run about $50 to $60 and a repairman average should be less than $200 and more than $150 hope this helps. Contact me for any questions you may have. I am more than willing to help.

CHANGING CHANNELS ALL THE TIME


I have seen some RCA TV's with this problem and it has usually been a switch going bad on the keypad of the tv. This can be confirmed by disconnecting the plug from the control panel to the main chassis.If you are lucky, and the ir rcvr for the remote is not on the control board, you can still control tv with the remote.Good luck.

I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00
