    I have a 32 inch Digital/Analog LCD Symphonic WF 32L6 tv. It is less than 2 years old. It was on and working and then just turned off and now it will not come on.

I had the exact same issue . The TV literally stopped working 2 year after the manufacture date. Since I had nothing to loose I opened it up and found that the fuse had blown. I put a new one in and if blew also. I work with some electrical engineers and they said first to look at the Diodestv won't turn on no light in front - mag-glass_10x10.gif. They lent me their diode checker, and the first diode I checked was bad. I'm sorry I don't have any pictures but it was one of the diodes closest to the where the power cord connects to the board. I took the board out and brought it to work and had the electrical guys pull the diode. I got a replacement diode, (.20 cents or so) and had them solder it back in. The Diode number is IN540, you can buy these online, DIGIKEY.COM is one place too look. I took it home put everything back together, including a new fuse and BOOM it fired right up. I did this about a mounth ago and it is still going strong, I should probably knock on wood right about now. If you have an questions please feel free to ask. I am not a TV repair guy, just someone who got lucky. Good luck!

Replace the power supply.

    the power supply is internal to the set, it provides the 24 volts(to light the lamps), 5volt (standby) voltages,and various other voltges to run the set. since you said the the red light doesn't light on the front of the unit the 5 volt standby is not running. this can be a fuse issue also. now the power supply is the part of the unit that is allways running (as long as it is pluged in it is always on). since you have no indicator light,= no running power supply. yes a tech must do the repair unless you are so inclined to take it apart yourself. if you do you may cause more damage so go at it at your own risk.

My set is plugged into a cable box. the tv will not turn on either manually or with the remote.


Plug the power cord directly into a wall power outlet, and make sure that the standby light is lit (turn it on/off manually to see if anything changes). If there isn't any light, then it's most likely broken.
If the TV works again, being plugged into the power outlet in the wall, then the problem is with the cable box (i bet you figured that out too).

We came home from a weekend vacation and the TV won't turn on at all. there are no lights, no response from the remote, nothing. It worked fine on Friday and now Sunday, it is shot. I thought possibly...


Hi, Check that the plug has power. Use a light to do this. Also check the TV cord maybe bad.
Check breaker pannel. Make absolute sure that you have power getting to the TV. If all is good you need a repairman. Good luck

Tv wont turn on worked fine last night


If there is no power at all, then the problem is likely the power supply unit.
The PSU must be tested, then eventually replaced.

Tv won't turn on


I had a similar problem when there was a power outage or the lights went briefly out. I unplugged the TV and left it for a few days/weeks and then plugged it in and the TV worked. I think newer TVs should be treated like a home computer and put them on surge protectors.

Power button is green - no blinks / no picture / no sound


Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

Power light blinks, but tv won't come on


I have the 52" version of the Viera model. Mine went out last night and started blinking twice over and over again. I suspected overheating so i just went to bed and tried it in the morning with no luck. Then I unplugged it for more than ten minutes and plugged it back in and everything worked fine. I hope this helps.
