Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My tv flashed on and off and left with 6 blinking lights. Did a power reset and tv powers up with Sony on the screen then goes dark but the green light stays on. Screen is dark. Which panel is bad.


Probably the back light inverter is faulty . Before going to buy a new inverter board tey to check the power supply. Which the bellow added video to know how to check a power supply board. You have to check the 24V power sto the inverter board from the power supply. if its not there then the problem is with power board. If its ok then you have to go for a new inverter board. Also try to replace the electrolytic capacitors in the power supply board. some times bad electrolytic capacitors can lead to back light failure.

I have a hisense 55" tv the screen is really dark but is still working knowing because I did the flash light test. Would it be my power supply panel


If the back light inverters are mounted on the power supply board, then yes, the power supply board needs replacing. If the inverters are on a separate board, then replace that one. Use a voltmeter to check if the different voltages produced by the power supply are present and within +or- 5% of the expected voltage.

My proscan TV was working fine. then the video went and now no audio.. it lights up briefly when u turn on. then screen goes dark.. is this fixable or better to get a new tv..It is only 3 years old


I believe it's fixable! Take a look on your video and audio cables (behind the TV, the red, yellow and white ones). They must have a problem. Already happened to me!
I hope I've helped...
