Question about Televison & Video
This is an indication of out-of-regulation of B+(supply voltage), missing output voltage in the power supply section. It must be check upon power on and prior from detecting with the feedback circuitry to determine where the fault came from. If you don't have necessary tools and test instrument and can't troubleshoot the symptom, I would advice you to look for an experienced technician to isolate the problem.
Also, check if the unit is underwarranty, avail it because the manufacturer will fix it for free or a little charged only.
Let me know if you need further assistance.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
