Customer: replied 1 year ago.

A while back it used to come on when I press menu it doesn't come on now

Expert:  info tech replied 1 year ago.
OK and as you seen the LED blinking in the back of the set thats the logic board that appears to be working, its looking like a failed mainboard but some voltage checks with a meter are needed to verify that, can you do any work yourself with the set?use a meter and small tools?I will provide the procedure

Let me know please

I know nothing about fixing tvs

Expert:  info tech replied 1 year ago.
Yes I understand actually modern TVs do lend themselves to being fixed by the owner however it depends entirely on the owners practicality for example the work would be suited to someone who uses small tools and test equipment like a meter for example a car mechanic/or mechanic generally/a electrician/a do-it-yourself person would be suited to do this being able to use a meter in addition is a great help, it does not suit everyone however.

If you need a tech www.tvrepairpros.com will locate a tech in your area

Let me know if I can do anything else

Have a great day and thank you kindly for the rating
