Your TV is in protect mode. A problem was detected and the set shutdown. Is there a pattern to the blinking?

1. hold the [vol-] and [menu] button.
2. while holding those, press the [power] button and let go of the [power]button only
3. wait 5 seconds then let go of [vol-] and [menu]
4. wait for a while(approx 30secs).....do you get a picture

This works for the JVC models that end in "9" and end in "0"

SOURCE: 26" Samsung flatscreen LCD doesn't power up

Just to be a little more detailed, since I just fixed this problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

SOURCE: tv wont turn on power

power supply unit problem you have bad caps (capacitors) change all the caps or atleast the onces they leaking how do you see if they bad usually they are bold on the top instead of flat. change it with a higher voltage but the same UF. if it shows 10V-1000uf you change to 16V-1000uf or if it fits a 25V-1000uf.

Fault at its main digital 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. 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.

Flatscreen tv no picture instead of green light for power it blinks red


The led blinking is an error code from the internal processor - defining the nature/area of the TV's internal problem.
A service manual (if available) will de-cipher the code.
The tv will probably need to be repaired by a service technician.
