Thanks for the response on U405 on back of main board. I changed this to fix the issue as well. Even though the post is old it worked great.
More info on issue was TV was completely dead & wouldn't power on at all (even the standby LED wouldn't light up at all). I verified power supply board was good by measuring the power board & main board connection cable & was getting the right Volts DC needed on the cable pins into the main board.
I used part # MAX810LEUR+T as a compatible part (ordered from Digikey. It's a very small surface mount 3 pin component & was a bit of a pain to solder on.

Hello,

Your power supply board is not yet dead, u know basic electronics' and soldering? You have to open the back cover of the television check for dry soldering on the printed circuit board , if found resolder but if not Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem...

The power LED lite indicator is solid green,but no pic.?This tv is very fixable,take it to the shop,they will order a refurbish circuit board call a T-con board from some wesites source and repalaced it for u.This should cost u half the price of a new tv.If ur power LED lite indicator is blinking and no pic.,they will replaced defective leakages capacitors in the power supply board,or replaced the power board all together.

I have a sharp 37" lcd tv,model # lc37sb24u. no pix or sound, power lite comes on about 10 seconds then power and opc lites alternate on and off. thanks RON


This problems very common in Sharp LCD tvs.The Tuner signal board have problems,every times the power LED,OPC LED lites up,just push the power button on again,wait see if the LCD backlight lite up and works,not the Power lite and the OPC lite LEDS flashes again.You,just have to push the power button again,sometimes u have to push the power button at least 6 or 7 times to get the Power LED stable,and then LCD backlight,come on than the tv work.Not sure,but if the Power and OPC lites keep flashing,after u pushes the power button at lest 10 or 12 times,and the LCD backlight dosen't come on and the tv don't work.I think,it time to change the Tuner board is completely dead.I have a Sharp LCD tv, I do this everytimes pushing the power button at least 3 or 4 than the power LED stable,and the LCD backlight come on than the tv work.Not a plaw in the power supply like those capacitors in many LCD models tvs,but some included Sharp Tvs is the Tuner signal board is not very good in design,use the tv awhile the Tuner signal board have problems recieving the power to it Tuner board components.

42PFL5432D/37 WONT COME ON DEAD/NO POWER LED DISPLAY/2 YEARS OLD


An issue i came across with this particular model tv was there were two (2) 3300 micro-farad 25v caps on the power board that have gone bad, preventing the tv from starting up. I replace those two capacitors and it started right up! I suggest having a tech do it, unless u have experience with electronics. I cannot be held responsible for any damage done to your tv, warranties voided, or shocks you may receive. but that should get it to start back up.

Roland JC-55 amp stopped working


Sounds like a transformer problem or something else in the power section..maybe even a transistor....since the LED status light would be direct from DC power. Take it to a trusted audio electronic tech and get it looked at. Keep in mind that these amps are about $150-$200 used on Ebay so don't spend too much getting it fixed if it is indeed a transformer. I'd definatley get it looked at. I have a JC-77 and it rocks for clean!
