Flyback transformer and horizontal output transistor change out

I am trying to change out a flyback transformer and horizontal output transistor on a RCA Scenium HDTV/DVD Monitor 52-Inch Model # D52w135D.And I need to know where do I disconnect the wires from,is it the flyback transformer and the horizontal output transistor itself,or do I disconnect it from the other end.because I can't get to the other end from where I am. And I can't seem to get them out of the flyback transformer nor the horizontal output transistor,so could you give me some advise on what i'm doing wrong.

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.

My RCA projection TV HD56W66 tries to start three times then powers off The flyback squeals each time. Any ideas?


you most likely have a bad flyback transformer as well as the hot horizontal output transistor.

I disagree with given info, this tv has no horizontal output transistor because it is dlp tv.
3 red light blink means lamp cover is not placed back properly after lamp replacement/ lamp checking. Make sure lamp cover is fixed back in its place securely and tight.

HORIZONTAL OUTPUT TRNSISTOR SHORTS WHEN POWER ON TV


ALL the next is with the tv unplugged (NO NO power)
  • resold the jungle (video processor) all around
  • following the horizontal drive pulse path and arriving to the horizontal area just after the horizontal transformer and in the base of the horizontal DRIVER there is a electrolytic capacitor (if this chassis uses this one,) Change it (maybe is dry)
  • solder all components i just told you in the last step. horizontal driver, transformer, etc
  • remember:
  • if a transistor is blowing with no reason (there is a reason: the collector receives 130 volts but cannot hold it forever, It has to be in some place. if the switching pulse doesn't arrive to it the transistor throws this 130 volts and burning itself. i hope it is help full.

First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..


Hope this may help;

If you can find the horizontal output transistor which is located near the flyback transformer,one lead of this drive transformer is connected to the base lead. (horizontal output transistor). There may be a little coil in series with this lead going to the transistor.
