Fault in the main power supply regulator 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. Surf the site with patience. 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.

My sharpe tv won't turn on the green light is on but it won't start and you can't turn it off or on with the remote or button. You must unplug it for the green light to go off.


Please attempt to bring up an internal image on the screen by pressing Menu button on TVs remote, and on the TV panel itself. Do the same using the Volume button to see if the volume bar appears. If they appear, check the cords of the sources connected to the TV; make sure they are secure, and not loose.
If doesn't appear going to need a circuit board replacement.

Hi,

Most likely you have turned on the sleep function. 2nd button from the left on the top of the remote hand unit. Keep pressing until "sleep off" appears on-screen.

Or

Timer in user's menu is activated to turn off TV a specific time. Go to timer menu and adjust timer, then push cancel on the remote, this should reset timer to zero. Same with current time, adjust and select cancel, this should reset current time.

If you do not have the original remote, you are in trouble. Service tech will have remote.

Please take these actions before we try yet another universal programmable remote 1. Clean the IR screen on your tv set. It will often appear clear in view with a reflective window which often has a black, blue, or red tint to it 2. Clean the same window on the programmable remote 3. From tons of experience, I've noticed that Sony tends to provide the most compatible remote for replacements 4. Please confirm with me which codes your attempting to use when programming, and type /model number of the universal remote 5. Keep in mind that the remote that does not work as a replacment may very well be exchanged 6. Only use approved batteries for your remote and keep in mind that rechargeable batteries account for 50 percent of electronic errors 7. If your old remote simply stopped working for no reason at all, then we may have a communication problem with the tv combo set itself. 8. Ensure that the tv set is ready and able to receive a signal by setting it to the factory defaults within the settings menu 9. If we know why your older remote simply stopped transmitting the signal, we will acheive a must faster solution 10. Please attempt a fresh set of batteries in the older remote to determine the root cause behind the transmission problem 10. Check your power cord for crimping, dents, or pinched underneath unit. Each of these activities will cause power to stop transmitting to your unit 11. the digital display is not popular for having problems. 12. Ensure that you press the power on button on the digital display firmly at an attempt to power the unit on. 13. If you still have not recieved power, we will continue to troubleshoot the internal portions
