This is a problem with the ATSC channel's reception. Usually switching to another channel and back solves the problem.

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.

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.

I have a Sharp Aquos 52" LC-52LE810UN. I turned the tv on and assuming that my cablevision box is working, what do I do in settings or other aspect of the tv to make the 1080i work. I have another box...


Actually the cablevision box determines the 1080i. Once it is set on that box the television simply displays it. The cablevision box will have to be connected to the television with component cables or one hdmi cable in order for you to be able to choose 1080i on it. Usually there are resolution numbers on the side of the cable box that tell you if it's on 480, 720, or 1080. There is a red light next to the one the cable box is displaying. If this is not the right kind of cable box for that then you will need to get another one from Cablevision or just eliminate the box entirely and run the cable straight to the television. Yes you can do that and use the television's digital tuner for a beautiful, crisp picture. After removing the cable box and screwing the coax cable onto the back of the television you will have to press the input button and scroll up to TV and press enter (use a Sharp remote). Then press menu and scoll over to setup and down to CH setup. Then scroll to CH search and begin searching for the available channels. You will now use a Sharp remote to change channels.

I have a brand new Aquos 52" LED TV and I accidentally locked remote operation and THEN found out the front touch screen panel was broken. Any way to manually reset the TV or remote to gain access to...


While the set is turned on, you need to hold the power button until the set shuts off and the led in the middle of the bottom flashes once. Then quickly release the power button and press the vol - and input buttons together along with the power button. Your TV should then turn on and should show you a blue box with the letter K. Now press the vol- and channel- buttons at the same time. You should now be in the service menu. With your remote arrow up until the top line says industry init. Arrow to the right and hit enter. Screen should turn green and say factory init success. I hope this helps you.
