These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: my power light on hitachi lcd is flashing red and

Sadly to the end I can now explain the "problem" of my question by myself ...
Because I'm was not sure if I can handle the "problem" by myself I gave the Screen to a technican at our City with all the Information I found until this point (By the way my suspicion was the defect of something at the power supply unit). Two days later he gave me a call with the information about the error: An error at the power supply unit - spare parts => 50€, Work => 200€).
Unhappily im not yet got at soldering on screens, but for 250€ i would have made a good course for this (and if I can establish i will learn it).

So now again a bit more objectively:
Error / Problem:
TV - Step 1: Power Off
TV - Step 2: Stand-By
TV - Step 3: Power-On
TV - Step 4: Short flashing picture
TV - Step 5: Reverse to Step 1

Solution:
1. Find the defect Fuse/Safe/...
2. Buy the Spare part at eshop2.euras.com
3. Change the parts -> et voilá

Hopefully I could have been a little help for someone.
With kind regards,
NatureOneFreak

Remote stopped working all together. Replaced the remote and it still doesn't work. Tried replaceing the batteries as well. Light on remote flashes but that's about it. It is a Sharp Aquos HDTV not sure of...


If the TV still works fine and it's just the remote malfunctioning, try removing the batteries from the original remote and leave them out for 10-15 minutes. Put the batteries back in and try the remote.

Lcd sharp tv flashing green light


Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.
