Try to disconnect all power to the unit and allow it to set for 30 minutes.
Next, after the unit has set, re-connect the power input to the unit and watch the front panel.
Now, try to start unit with remote. If the power light flashes or remains red, you have a problem in the power supply and will have to have several capacitors replaced.
If the unit starts up and then goes back to a flashing or constant red power light the power supply will need repair or replacement.
I hope this information has helped you

Hi,

This problem is likely a failed power supply. This is a known issue with this model TV. It will normally occur soon after the warrenty expires. It can also be caused by a voltage surge produced by a power failure. You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad. This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

Let me know, if need further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!


    Sorry to be rude, there is NO QUICK FIX. Had been there , i would be the first one to inform you. If your TV doesn't Turn on, it need to proper investigate it unless you haven't plugged the Cord in the switch. These are electronic items. If there are Quick Fix's for these, there would not be any repair shops. People might punch the button and it's all set.

    It's my humble request, try to understand the Logic.

    Thanks for using ' Fixya ' and have a nice day!!

The following could be the reason: 1. The Wall socket bad. 2. The wall plug bad. 3. The power supply unit bad. Up till here there would be no red power on light on the TV. 4. If the power red light is glowing, then the fault lies in the circuit beyond the power supply unit. 5. If there is red light, and sound, then the display IC is bad. 6. If there is red light and pic but no sound then the audio IC is bad.

Cracking speakers when tv turns on


If other electronics are too close to a TV this is a common problem. Try moving the 2 items at least 2 foot away and see if that helps.
You may not want to leave them there, but at least you will know if that's the problem!
