Question about Sharp Aquos LC-45GD4U 45 in. LCD HDTV

1 Answer

Sharp LC-30HV4U You seem to have knowledge on the Sharp LCD's. I have had intermittant problems getting my flatscreen to turn on, then when it decides to turn on I can watch it for awhile then it turns off by itself. Usually after sitting for awhile, sometimes days, I can get it to turn back on however it will turn itself off again. I have been told it may be a board of some kind but can't get any definate answers. Any help would be greatky apprceiated. Thanks, Al G

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.

My Sharp Aquos LC-32D44U Is malfunctioning.


The main power supply regulator section circuit fault. 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. http://electronicshelponline.blogspot.com/ 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.

I have a sharp aquos tv model lc-32m400x. When i turn the power on via button at the back the green light comes on for about 10secs then turns to red and flashes about every 11/2 - 2secs. Any ideas.


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.

Why won't my LC-32CHF5111K tv turn on I have a steady glowing red stand by light


It could be the power supply board on the TV. It could also be a blown capacitor on one of the circuit boards.
