    Tried the RESET routine, no effect. Same syptoms as before, RED power light lit, no screen, no sound. Pressing the powere button on remotemake the power LED blink each time you press the power button, otherwise no other response from unit.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

I have a Sharp flat - clip_image001.jpg
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

Regards,
VOTIT

    This a cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the TV turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

    Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

    Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

    Good luck:

I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.


How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.
