I would try soldering the flyback terminals on the PC board and also re solder around the Horizontal and vertical yoke pins as well as the transformer and line coils. Rca has ad some problems with bad solder problems on the circuit boards. let me know if I can assist you further.

Power supply or high voltage supply problem---set well known for bad solder connections in and around the high voltage transformer---also known in early models for the high voltage splitter to be bad.

typical high voltage transformer:

Screen pulses white. off and on, lite on front goes from green to red. model is Hisense TL2020


that problem is usually cause of shorted fly-back transformer that give a very high voltage you can find that by hanging all secondary connection of fly-back then power it again then use your multimeter and range it to dc then ground the black prove to the body of your unit test the b-plus voltage if the supply is flickering it means your fly-back is shorted and if the supply is stable it means you have a shorted diode in secondary thank you

When I turn the tv on it has no pic and then turns itself off but would come on after about 5 times of turning it back on but now it just had sound and no pic.


It seems that your Pulse Width Modulation drive ic on power supply or high voltage section fails. This can be resolve by replacing the IC MCZ3001d that will be found on your power supply or at the high voltage section.(near Fly back transformer) If you have basics knowledge in electronics and soldering, you can easily fix it.

Screen doesnt turn on then shuts power off


The fault you are describing is caused by a faulty fly back transformer. The fly back transformer provides the high voltage required to light up the picture tube/s on the set. Other than the fly back transformer there are a few components that supply the fly back with power that may have failed. Generally not overly expensive to fix

Will not power up


your problem is in flyback or high voltage section failure.

  • check horizontal output transistor
  • check fly back transformer.
  • check for supply to horizontal section as high voltage from power supply may create such problem
  • as this failure is due high voltage section so it is better to take skilled technician help.
  • good luck.

Powers on, audio works, no video at all


First, need to narrow down the problem. Did you perhaps change the input source? To this point, change the input source, there should be text on screen that indicates what source is selected.....do you see this? Change the volume....do you see the volume level bar on the screen?

No pic no sound just ticking


This set normally has problems in the horizontal and high voltage circuit. The horizontal output will short out and I often change the high voltage transformer. The high voltage splitter is another one of the usual suspects. Since it's ticking at plug in, then, I would look at the secondary of the high voltage transformer or the regulator circuit. Checking the the horizontal output first for a short and if ok, checking the B+ voltage on the collector would be my next step. That should give a good thought as which direction to go. Hope this helps.
