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.
Sharp LC 60LE640U will not turn on power light just blinks
Those 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.

If blinks continue without any pause, the main board is faulty.

The tv menu keeps popping up
Hello,
The reason your television keeps popping up the menu is simply because, either the remote or the televisions menu button is stuck.
To test if it is the remote, remove the battery from the back of the remote and try to operate the television from the buttons on the television to see if it works, if it pops up, then it means the problem is not from the remote and its from the television.
Either ways you have to open the remote and clean the panel with naphthalene, then adjust the menu button on it. or you can as well get a new remote for your television if you cannot clean it on your own.
Also to fix the television if it is detected as the fault, get the appropriate screwdriver, open up the television, then try to locate the menu button, then you adjust it and try to operate with either the remote of the menu key on the television.
Once it is seen to be working, ensure that the television is properly coupled back.
Always make sure the keys on the coputer and the television are not pressed too hard.
Take care
Closed Caption won't turn off
cannot turn off closed caption on 27" insignia. the option screen which illustrates the closed caption category, is not highlighted and you cannot manually choose that option from the remote control.
I have a Sharp LC-45GX6U Display & TU-GD10U-T
I too have the same problem with the DC-DC board on the Sharp AVC. But I didn't spend the $134 for a replacement board (MCM or Newark).Instead, I used the reflow technique by placing the circuit board in the oven for 7 minutes at 475F. You need to cover the plastic header connectors (about 7 of them) with foils to protect them from direct heat (and melt). Take the board out of the oven and give a little pressure on all the ICs while the board is hot. Let it cool down and voila! The TV is working again...
I can look at tv for about hour and then it will start turning off. After it has that for 2 times you cant turn it back on for hours
Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
