Hi! Thank you for using Just Answer today! My name isXXXXX am happy to help you with this! Please bear with me and be patient as sometimes these issues take a little bit of figuring out before we know what's wrong. If you could give me some more information it will be very helpful: -What is the model number for the television? (this can be found on the back of the unit) -How old is the unit?-Is the light blinking a code? (example 6 blinsk pause 6 blinks pause repeat)
Please give me this information and I will be happy to assist you further. Thank you, Tim Nolan
This is a very common problem with your tv, what has most likely happened (about 99% of the time) is the power supply is failing, more specifically there are a few caps in the power supply that have most likely failed. The unit will require component replacement to get it working again. Do you have any electronic repair experience, test equipment, and soldering equipment? If so I can assist you with this repair. If you do not have the above equipment and skills a repairman will be required for this repair, you can expect the bill to be around $200.
I am sorry that I don't have a magic button or a quick fix for you on this one, but component replacement will be required.
What you need to do is remove the back cover and inspect the power supply for any capacitors that have bubbled tops. Let me know what you find....If you are unsure what you are looking for you can post a picture to me and I will inspect for you.
