Mom's Sharp Aquos TV no sound or picture there is a green flashing light where the power light is I heled the volume up and channel down while the TV was unplugged. plugged it back in sound no picture


These 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.
http://electro-medical.blogspot.com/
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

How to fix Sharp LCD model # LC-32SB23U flashing green power light and check and...


If the green power light keeps flashing on and off every second and tv will not power on unplug the tv for 5 minutes, then try this. Keep holding the VOL+ and CH- buttons down while you plug the tv cord back into the wall ac outlet till you get sound and picture for a second or two. You should be able to turn the tv on and off with the power button now. Next turn the power button off and unplug the tv for a few seconds and then plug it back in and turn the power button back on. Watch the screen and see if the sound and picture comes on, best to check in a dark room to see better, if sound stays on and picture comes on a few seconds and back off you have a bad CCFL backlight lamp in the LCD panel. This tv hads (10) CCFL lamps part # RLMPLA029WJN1 cost $15.93 at www.partstore.com or $19.49 at www.encompassparts.com in it and if one is burned out it will not let the tv picture be powered on till it is replaced. To check and replace the CCFL lamp you will have to unplug the ac cord from the tv back and remove 10 screws holding the back on. With back removed unplug the wire plug on the power button circuit at top left side of the black LCD screen trim, remove 4 screws holding the top of black trim, lay speakers off it, and release trim clips, (4) at top and (2) at bottom with a flat screw driver, and lower the trim to unclip the LED circuit board at bottom left side on the trim, leave the wiring pluged into this LED circuit board . With trim removed, at top of LCD panel remove the (2) PC ribbon wire clips with thumb nail by lifting up on it to release the flat PC ribbon wire. Lay the tv back on a soft pillow with screen up, and look on the LCD panel front for and remove the (10) silver screws 1/2" long with an arrow mark beside them. Do not remove any gold colored screws or any without marks. The LCD panel screen can now be lifted off, lift the backlight plastic thin sheeting and thick sheet off to see the CCFL lamps. Stand tv up and plug the ac cord back into the power supply inverter circuit board and plug the power button plug wire back in its circuit board on the LCD black trim panel, and power the tv on while looking at the CCFL lamps. If the lamp is dim or burned out, take the (2) white plastic covers off the side ends of the lamps with a flat screw driver and unclip the lamp to replace it, Check the bad lamp sockets, part # QSOCFA003WJZZ, by putting a good lamp in it and if it lights up the sockets are good and the bad lamp was the problem. If all the CCFL lamps do not light up, unclip the top lamps and move them to differant sockets to the center and the center lamps to the top, if the lamps do not light up, then it is a bad power supply inverter circuit board the ac cord plugs into, part # RUNTKA448WJQZ , cost about $160.00 for new one or less if you buy a used one on www.ebay.com , replace it. If the power supply inverter circuit board is bad to replace it, unplug the (2) wire plugs at the top left side on the circuit board, take (3) screws marked with an arrow out, use a pair of sharp nose plyers and squeeze the plastic white tip holding the circuit board on the right side careful not to touch the high power circuit backlight plugs on the right side of the circuit board. Pull board straight out to unplug it. Replace with new board and tv should power on now.

No picture, no sound, power light steady green


First: Check the power outlet. Check it with a good lamp so you know you are getting power to the set.
Secondly: Check the power cord. Wiggle it around the molded ends to make sure it is not open inside the molded portion of the plugs.

Thirdly: If you know for sure the set is getting power and still no indication at all (you should be getting some little light on the front panel; standby indication) then there may be a fuse on the back panel or just inside the back cover (you will have to remove it; after unplugging the power cord) that needs replaced.

Fourthly: After all these checks if you are getting nothing, you may have some failure inside that is very serious. Normally we do not recommend serious repairs to a set over 4 years of age. This is because the set is likely to develop some other problem soon after the repair is made; further, the repairs are getting more expensive day by day while the price of new sets is coming down dramatically. Lastly, the new sets have better picture, longer lasting circuits and better features.

Hope this is a good solution for you.

thanks for your questions.

on the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.
