The problem seems to be with the power supply. There might be bad or burnt components such capacitors or rectifiers. Most of the times there are swollen caps which need replacement. I'd also suggest you to check the inverter board as well. The bad components are a result of heat or cold solders etc. If you want to repair it yourself then you should be having proper knowledge about the internal circuitry of the TV.
You should also have a multimeter and soldering equipments and the TV repair manual and schematics

Sharp Aquos has distorted colors


The set should be transported upright but that rarely causes these issues-----suspect either main signal board or also possible is the power supply (for voltages changing when set is on).

Also if set was opened look for all plugs to be seated--ones with cloth tape where they connect look at first.

failing that based on age of set consider having a technician look at it or if over 3 years consider a new set with extended warranty--70% of this type of set in our shop (100 plus sets at any time in for repair) are less than 3 years old.

I have a sharp aquos model Sharp Aquos LC-20B2U 20 in. LCD Television . it works great for about 2 years, then suddenly shut down by itself. then it turns on again for a variable time, then once again...


if your TV lights the indicator when you power it on,, your problem is your back light is busted you can replace that and when the indicator not lights the problem is your power supply you can fix it by finding defective parts by using multimeter usually the trouble that i encounter to power supply is open/change value of resistor leak capacitor and shorted diode and transistor such as regulator you're always welcome

TV shutting off by itself


The power supply is going bad and should be replaced but for the cost you will pay for the repair you can buy a new TV. Get the extended warranty, it will pay for itself.

this is due to a bad pc control board in the t.v. i had the same problem and that was the only way to fix it. i had to call sharp and they sent a tech to my house to install the new part.

Sharp Aquos LC-32D41U pictures problem


I have had exactly the same problem. Sounds daft but by not using the remote, and only using the power on/off switch on the TV itself, it is working perfectly...no idea why
Use the remore for changing programmes etc but not for on/off
Try it anyway because I know how annoying this is
