Blinking light is an error code. Count the blinks before they repeat. Check your manual in the troubleshooting section. If you can't find it, contact a Sharp service center or try and get a service manual. Reset info is also in the user manual but you can't do it if your set doesn't power up. Are you sure about the power board?

Check the power supply regulator board, with no load condition, and make confirm that the 12V supply line is OK, by connecting a 12V filament type bulb in place of load. if it is found OK, and no voltage drop occurs, be sure that the main board of this TV is faulty.

Relay clicks when applying power. Yellow light comes on. TV is dead otherwise. Power supply is outputting +5, 12, and 24 volts Mainboard (3647-0282-0150) has +5 and 12 volts always applied. Checked...


Amber light on means standby voltage is high. IF amber light does not go white when power button is pushed the its one of two things.
A. No power on command from main board. Usually labeled PS-On. Should go high from 3.3v or maybe 5volts. If not present Main is defective.

B. If the ps-on line is going high then your problem is a defective power supply.

My TV Wouldn't On


if no any power light indicator at the front of your tv that was mean the unit is dead set or no voltage that is circulating in the main board and other boards.if you can remove the rear cover of your tv, the first place to check will be the power supply board if the primary fuse was blown. if the fuse is blown with darkened color that was mean has shorted component either in the main board or in the power supply unit. if the fuse blown with clear color just replace with the same rating.

TV had no picture first and then no sound. I have unpugged TV and still nothing happens. There is a blinking red light on that can be seen from rear of TV ( 1 blink on and off). Thanks for your help.


Good day!

Please follow this procedure to fix your problem:
  1. Open the cover of your TV.Remove all screws at the back.
  2. Next,power ON the TV and check the output voltage of power supply using voltmeter.
  3. It should have not less than 5vdc for system board,12vdc for sounds and 24vdc for inverter board.If the 3 supplies are got a voltage drop your power supply had problem.For example if you check the 5vdc then the reading is 4.50vdc only.
  4. If you have voltage drop,check some leak/bulge on top capacitor on power supply.replace it using soldering iron and soldering pump.
  5. When the power supply looks like OK,no voltage drop and no leak/bulge on top capacitor.The problem is your system board or main board.There's no easy remedy for that.You have to replace the whole system board.
A Power supply is like this..(It is not actually look like yours but it was just for your Idea)

The tv powers up for about 30 seconds and then the power light starts blinking fast and the tv shuts off i think it is the main board but any suggestions would help


Good day.

This the procedure that you have to do.

  1. Remove the cover of your TV.
  2. Power on the TV to apply voltage data.
  3. Check the power supply output.5vdc for main board supply,12v for the sounds and 24vdc for back-light inverter.
  4. If any of the 3 supplies are missing or got a voltage drop,there's a problem with your power supply.Check some leak/bulging top capacitor.
  5. If the 3 supplies are OK,the problem is on the main board of your TV.Replace it.

I hope this solution will be helpful.Thank you for using FixYa.Good luck.

What causes a 32c110u screen to blank off after about 2 seconds of powering on.


Good day.
This are the procedures to find out the causes:
  1. Open the back cover by removing all screws.
  2. Power ON the TV to perform voltage data.
  3. Check the output voltage of power supply if there's a 5vdc for main board,12vdc for sounds and 24vdc for the inverter board.If any of the 3 is missing or having voltage drop.The problem is on the power supply,check some open resistor or leak/bulging on top capacitor.
  4. If your power supply is OK and the 3 supplies that mention above are complete and no voltage drop and your TV is having sounds but no picture.Check output voltage of the inverter board it should have 500vdc so be careful.
  5. If the 1 to 4 steps are properly work the problem is the main board.
I hope this solution will be helpful.Thank you for using Fixya for assistance and good luck.

Green light comes on no picmor sound


Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

You should check the 12 volts capacitors on your power supply for dry or leaky, bulging conditions.
Replacing those capacitors will restore the functionality of your TV.
