It cud be a fuse that has shot, is that a smart tv or older model if its an older modl i know that replacing the fuse may solve the problem you can find anything you need here..www.discountbargainprices.net
Testimonial: "I don't think it is a fuse, I had taken the back off and unplugged everything and looked for blown capacitors but didn't see any. Once put together It had worked again. I turned it off and later went to test it again and no picture again. Not sure which board is bad but Im sure its a board."

This could be a scan amplifier failure, and there is a loss of high voltage to the CRT. Part of the power supply may have also failed. In these sets, if the CRT emission goes low in emission, or the CRT goes defective, the bias supply to the CRT will go in to protect.
An experienced TV service tech can troubleshoot the set and give you an estimate for service. Considering the age of the set, the cost of service may not be worth it.

Please post both the exact model number (on the back) and the blink count. The standby light should be blinking a repeated pattern. That info will indicate the problem circuit and allow us to provide you with the proper parts/steps to resolve this.
Thanks,

It sounds like a convergence problem. A fairly common reason for thisproblem is the convergence chips have failed. They are usually referredto as "STK" chips since the model number of these chips start with STK.I will put a link to another part of this site where someone has postedpictures and a link where to get the parts should you decide to fix ityourself. Look at Ecullier2012's posting. Jean's posted site will notfix this problem. Hope this helps you out. Let me know.
