Leak in the ceiling and water entered sharp TV

This model was known for bad capacitors in the power board, have you tested them and or power supply voltages?

Check the power relay. Check power supply voltages.

Thank you Much. I called SHARP for service code reading with absolutely NO help. Was told to call a service tech. I can fix this and at least know what to look for.

I have a 70 inch aqua sharp tv. The model number is LC-70LE857U. The stand by light blinks 2 times slow, 5 times fast. Tried resetting the TV.. Nothing changed. Please help.

How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

this is what I've done to our tv, same problem so I solved it by doing ths : first turn on your tv then let it keep on blinking then directly unplug the tv don't turn off the tv . plug again the tv then you'll see that second red light is not blinking but still it still red light the first one, just unplug it again by not turning off the tv then while unplug click the on off button to off the tv the plug again the tv and turn it on. and finally the red light will turn to green it means the tv is now ok! yehey. sorry for my english I'm notgood speaking english :)

I got a Sharp Aquos Quattron LC-60LE847U, a 60inch LED TV, I only brought it for a year and 4 months, factory only a have one year warranty. Last week when my kid try to turn on the TV, the TV power light keep repeat blinking in 2 slow and 5 fast sequence, don't know what did it mean. When I press the power button, the light will stay on for few seconds and it kept blinking after, the TV cannot turn on at all.
My kid have called the Sharp help line in US, number found in user manual, but the Canada help line are different number, it is 1-877-278-6709, they told my kid to unplug the TV, hold down the Input and the Volume down key, then plug the power back on, the TV can turn into service mode, it have a K icon on the screen, but every time I selected the menu, it went away very quick. Then the customer assistant told my kid to call service.
When I did a lot of research, every solution seems to point to the power supply, so I bought a power supply from ebay, replaced it, it does the same thing, no different at all, then I turn the TV back on in service mode, to try to do a reset from the menu, upgrade the firmware, re-seat all ribbon cables of the main board and the middle logic board (Not sure what is that board call, it is in the middle of the TV), neither way can make any different, the TV light still blinking in same sequence.
So I kept doing the research, I find out another way to reset the TV back to factory setting just by holding down the Volume up and Channel down, then plug in the TV, kept hold it down those 2 buttons until the TV came back on. TV will reset for just by doing this. Happy news, problem seems to get fixed, but not 100 %. The TV seems no problem to turn off and on after reset, but if I unplugged it, the blinking problem will come back, but if I reset it one more time, it will works again until I unplug it again. It is better than completely dead.
Then I unplug the TV, removed all ribbon cables (6 ribbon connectors), use sand paper to clean all the ribbon cable contacts, don't rub it too hard in case the cable contacts get destroy, then re-seat all the ribbon cables. After I did that, everything back to normal and my TV got fixed completely.
This seems to be my way to fix it, not sure everyone can use the same method to fix their blinking power light problem, but I hope this tips can help some people to save big buck to the Sharp service. This TV is over $2000 dollars and I brought few pair of the expensive 3D glasses, I do hope it can last longer, didn't expect it have problem already, it just less than a year and half old and even I bought the power supply to tried to fix it but I ended up didn't needed to spend any money and solved the problem.
Hope this helps.

Dear customer,
Sharp TVs often require you to press the TV Tuning preset key which is a yellow function key.        
   Setting Up Your Sharp TV
Turn on your TV.

1. On your Tune In remote, press TV and release.
2. Press and hold Set until the green light on Tune In blinks once, pauses and then blinks twice. Now release the Set key.
3. Enter the first three-digit TV code for your Sharp from the list which follows:
   093, 165, 039
   These codes are listed in order of popularity, and the green light will blink twice if you perform this procedure correctly.
4. Aim Tune In at your TV and press Power. Your TV should turn off. If it does not, repeat steps 2-5, trying each code listed in step 4 until you find the one that operates your TV.

Now Test Your TVWhy test? Many times more than one code appears to work. Testing is desirable to be sure you have the correct code for your TV or the other devices you are setting up.

1. Press the Power key to turn on the TV, then press mute, channel scan ("CH") and volume ("VOL") keys. Tune channels 7 and 11 by entering the number followed by the Enter key.
