In this video today we are going to take a look at a Sharp 32 inch TV and look at how to diagnose if you have bad lamps or a bad power supply.
You can see the LED flashing on the main board as it starts to boot up. The backlights come up and then they go out again. So, right now we have the blinking green lights, so I am going to reset the TV. I will reset the TV by holding down the power button and if you hold it down for a few seconds, it is going to go red. The next step is to hit the power button once and then it goes to orange. Then you can press and hold it and the TV will turn off. Sometimes you will find when you replace a main board or a power supply that you may need to reset the TV. You have to go through that sequence and then when you power it back on again, it will run normally.
So now we can go ahead and power on the TV and we have a green light, which is what you would normally expect to see. We are going to see the backlights come up briefly and then shutoff. There we go, the backlights just went out and then it will start to flash our error code, which is the blinking green light.
The next step is we will play with the power supply and see if we actually have bad lamps. We have gone ahead and pulled the power supply out of the TV. On this power supply we are looking for one specific component, it is Main IC, IC 7501. Just over to the left from there is a little capacitor, C7558, which is the one we are interested in.
What we want to do is just add a bit of solder across the top of this to act like a jumper and this is going to remove the error detection for the TV.
So if there is problem and it detects that the lamp is not firing correctly, it is going to allow it to stay on because you are shorting the error detection line out.
We are going to take our iron and get a little bit of solder on it and since this is so small, you will want to do this quickly, otherwise you risk moving the entire cap.
There we go, that looks good. So now that we have jumpered that out, we can go ahead and put the power supply back in the TV.
We have put the power supply back in and we can go ahead and turn the TV back on. There we go, we can see that the TV has turned on and it has stayed up. That shows us the power supply is good and the problem is most likely going to be with the backlights.
So this error code, could be caused by a lamp going out, which would show up as a dark band across the screen, otherwise it could be a lamp that is starting to fail that is causing this error code and may still be lit up, but it may be causing enough of a problem in the power supply to cause it to shutoff. If the lamps are defective, it is possible to replace them, but it is a pretty involved task and it does require taking apart the panel and getting replacement lamps. This is doable but is a more advanced repair. If the problem appears to be the power supply, then replace the power supply and that should get you up and running. In order to get the error detection working again for your TV, you will want to remove the jumper and that little bit of solder that you added. If jumpering the protection out does allow the TV to stay on, in theory you could run it like this, but remember you just removed a protective part of your TV and it could cause other problems and at that point will not force the TV to shutoff if there is an error. Do so at your own risk and this is not recommended. Thank you for watching one of our many tutorials here at ShopJimmy.com.

I have a problem with my SHARP LC-42LB261u
TV Turns on.... No pictures...But with all the lights off in the room you can faintly see the screen with image [ie.. Settings menu] The screen flashes to show the settings roughly every 2 seconds...and just repeats continuously... Replaced the t-con board [3 separate t-con boards...no change in brightness or the screen from flashing.. We disconnected the t-con board to see if there was a change, obviously the picture with settings and such did not appear, but the faint backlight flashing every 2 seconds or so still remained constant...
Should we replace the power supply board or the input board? Any ideas would be helpful!

LC-32D44U . Wasn't turning on. Power light was blinking. I followed your instructions and did a reset. Turned it on. Displayed typical TV static from no signal. Menus/channel #s displayed clearly. Then after a few minutes the entire screen began flashing solid green.

Repair is not change the entire card, in my country repair is to save the original card by changing the component or components that are damaged in it, it is illogical to change an entire card for one or two damaged components.

I have a Sharp TV 65" Model LC-65LE643U, it was dead after a storm lighting couple days ago, but I am not sure if the problem actually is the power supply or not, how can I test the board
My TV is dead and it has no power at all, and no standby light.

Hi all, I'm having Sharp Aquos LC-32CFE6452E and I can't do the hard reset. I've tried the steps with Vol- + Source buttons held until I plug it in the electricity and there is no menu for reset. Any ideas please. The real problem is that after somethime when I use the TV, some of the chanels dissapeares, but on the rest TVs they are available. The other problem is that the TV is veeery slow. Whe I turn it ON, i should wait some time to connect the WiFi, to check for USB or else, and then it is possible to change the chanels, or to volume UP or Down.

Hello Jimmyshop, my TV IS SHARP LC32X20E, it happens to me that after a lamp error the TV has entered in protection, the monitor can no longer be accessed, and it is impossible to carry out the procedures to reset lamp errors.
I tried everything, the initial reset by pressing POWER for few sex to reset and n result. Disconnecting the AC, power and restarting with the procedure "VOL (-) / INPUT" and no result. No one ofe the knowed procedures do work because the monitor does not turn on and I can not see anything, and impossibile do any.
Can you help me, thanks in advance.
