Spectroniq tv doesn't turn on, lights off.


The fuse is inside--power cord should go almost direct to it--beyond that if fuse good is power supply for the set.

My LG Flatron rear projection TV won't turn on. The on/off power button is not turning the TV on. There is no click sound and the red light doesn't come on. The TV is connected to mains power and ther


tried with other ac outlet doesn't work?. if still won't turn on, at this time you will need to remove the rear cover to gain access the internal part. since your tv doesn't have any power indicator, the first place to be checked will be the power supply board this is where the power connector cord is connected. now look for a blown fuse replaced with the same rating. but take note before you replaced the bad fuse you must need to have component testing in the power supply board which the cause of blown of the fuse. like shorted bridge diode, open resistance and defective mosfet or bad regulator ic.at this time you will need a device called digital tester to check weather the parts need replacement.hope this can help good luck.

Wharfedale LCD2710HDAF no power to tv, checked cable and changed fuse a few times, new power lead? or is this a common problem?


Hi.

The power cord must be checked using a multimeter. The test is done reading impedance (ohms) between plug's prongs and contacts to TV power board.

If the power cord is OK and there is no power, then the problem is the power board inside the TV.

Regards.

Ginko.

The tv will not power on. Outlet is good. cord is good. Checked for electric on cord using meter.


Does the standby light come on at all or is it completely black?

Check to see if there is a fuse holder right where the power cord enters the back of the tv.

Good luck and keep us updated on your troubleshooting progress.

TV doesn't turn on. All power sources working.


Check the main power cord for proper fit from the wall too the tv. Make sure the cord is well fitted in the outlet and the tv. If the connection is in standing and there's ac voltage coming from the outlet.......then it
may be a blown fuse or a dead power supply circuit with-in the tv. If so, the tv needs to be serviced.

Tv won't turn on no light in front


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 Diodesmag-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!
