My phillips 42 inch lcd tv just went pop / bang and the picture disappeared - its now dead with no light - checked and replaced fuse

I would first look at the power supply board. it might be a removable fuse. unplug the TV first, remove the back of TV check the area to where the power cord comes into the TV. it should be real close to the power supply board.I have had a couple of quick fixes by just replacing the fuse. (that means it did it's job) if that doesn't fix it try to get the part # from the power supply board and check with Shop Jimmy.com for replacement board. (easy fix) take pictures of the back of TV with cover off and of the power supply board before u do anything. Leave the old board in place till the new one comes in. that way you won't forget where the cables went etc. Just be careful cause the dead board can still hold a charge so handle with care.

If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

good day hope I can be of help to you...is your TV "dead set" if so try these easy steps to trace the problem.. check the power cord for any burn or cut wires...check for a blown fuse... if you replace the fuse w/ same type and if it still been blown do not try to replace it again.. if this happen you have a defective power supply...let a certified technician now do the troubleshooting...good day...

hello have you checked the glass fuse inside the tv it will be in the power supply beware if replace the and blows again the you have a dead short circuit

Ur power supply board is dead,pop propally the capacitors pop,puff up.Check replaced the capacitors.Or replaced the whole power board.

Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.

check out for high voltage regulators near picture board. need servicing resoldering the whle unit and heated area..try it

Hold a flash light to the screen after it goes off and see if you can see a faint picture. Sounds like your backlight might be cutting off. Repair can be expensive but some of the newer units don't require the entire LCD to be replaced.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
