Hello [Sir/Ms], My name is XXXXX XXXXX Thank you for posting your question on Just Answer! I will be happy to help you with this problem,
How old is the set?
LED blinking pattern before it pauses and repeats?
Can I have your make and model?
on the rear of the TV
first would like for you to pull the power to all devices from the wall for 90secs let me know if it works
do you have the tools and skills to repair yourself?
tell me if this happens on all inputs such as a dvd player going straight to the tv?
unfortunately there is no quick fix for this problem.
The problem you are describing is a very common one in LCD sets like yours. The main board has failed board replacement in order to get the set working again. This repair should be done by a qualified technician, these sets can be difficult to someone who does not know what to do or touch,
If your going to complete this repair yourself please let me know and I will try and find the part for you if its available. Parts can cost you anywhere from 20-100 bucks depending on where you buy them at. But be careful I have seen people destroy good sets by not knowing what they are doing so just take that as a caution.
A good repair shop will run you somewhere between $100-$200 to repair this for you.
If you have any more questions please don't hesitate to ask!
Please only accept an answer when you are 100% satisfied and feel you can leave positive feedback. If I have answered your questions and met your needs even if the tv is repaired now or needs to go to the shop then please press the green "accept" button. Otherwise please feel free to ask anything else to get your problem resolved. Positive feedback is always appreciated!
