You have problems with your power up circuits. It is more than likely a fuse blown in some part of the TV that is keeping it from coming on. Also almost everything from a Computer to a $10.00 Calculator starts up by running a self diagnostics test on it's circuitry and if it detects any problems it will shut down or will go into a standby mode. Your TV has detected a problem some where in the circuitry and went into 'safe' or 'standby mode'. As I said in the beginning it could be a fuse, then again it could be about anything. I'm saying fuse because the heating and cooling of the element in the fuse often leads to metal fatigue and causes them to open up. Check the back and see if it has a 'user friendly' fuse panel and go from there. Look for a 30 amp blade fuse [it will be green] and see if its blown. I think that model has a history of blowing that particular fuse. If not, and you are not experienced in TV Repair don't attempt to take the back off and fix it your self, because there's places in there that will fix you good. You will need to take to a reputable TV Repair shop.
I hope it's the fuse and that this helped!
what you need is trouble shooting and a good digital tester to fix that problem. since the problem is power off start at the back light check if their is a small maldischarge at the module then check if their is a click on relay and then if the front LED is turn from red to green. then check the power supply if normal, check the low and high voltage except the stand by supply. then check the Y board the Va and Vs supply look for the blown fuse. and then the Z board check the 5v and Va supply, check also blown fuse.
yes thats is a common problem for all flat tv not only
sharp ;/ first theres is capacitor in power supply
you probly have few one there blow up and it could bee from the power section of your back light circuit
a good technician can fix that easy
HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.
FUSE CHECK LIST--
3A 12v- fuse----(242208600623) SM 3A 125v-fuse----(242208600657) 500 MA-fuse-----(242208611092)
Are all the caps good on the PSB.? Most sets have Samy boards and they used very shotty capacitors. Some show NO visual clues of being blown as in poped at the (X) top. They just vaporize/dry out. Do you have a cap tester?
i have a Philips 37pf9975/12 and after about 1hr it switches itself off the green light stops on the side but you loose picture and sound. if you push the stand by button it clicks for about 1 min and then turns itself back on???????
Check the 15v line that runs through all the boards, left, right and top.. If that has no power, then look on the ysus board (left one) there is a flyback reg (5pin) standard to-220 case surrouded by caps, it does dc to ac conversion, if you dont have the 15v output then the chip is bad. I just did 2 of these that had the same problem.
change the c97,c19 and c16 caps below is where I got mines.
Got it from a site called digi-key.com their phone
# is 1800-344-4539. The part #s are EF6225-ND you need 1of these, and
E6105-ND you need 2 of these, the cost is $16 for all. Let me know how
Contact Pioneer at 1-800-421-1404 about getting an in-home power supply replacement. This is a known issue with some plasma displays. Some of you would experience a loud pop and then the power supply fails. You get a red light below the ON button, when you press on, the red light will turn green for a second and then back to red. The plasma display will not turn on after the power supply fails. Call Pioneer at 1-800-421-1404.
