Sylvania6842PE M (Monitor only). I moved this unit and when I plugged it into the wall at its new location something popped inside and it will not power up. The green standby light goes on. When I push the power button a relay clicks inside and the yellow power light comes on for a fraction of a second before it goes back to the green standby light. I took the back off as my local supplier only gave me a 30 day warranty and noticed that a green LED flashes on one of the power boards. It glows steady for the fraction of a second the front yellow light comes on. I checked and read 15V on this powerboard at one of the connectors marked 15V but it was only there when the yellow light was on. I cannot see anything damaged although the pop could have been the sound of a capacitor exploding.

Re: No power up
Hi and welcome to FixYa,
Initially, to my understanding, it is required that plasma TV units when unplugged/power removed should allow sufficient time to dissipate whatever stored electrical energy is present inside, otherwise power supply failure is imminent.
To your concern, you may want to check out this site for possible board replacement.
Good luck and Thank you for using FixYa. Happy Holidays.
If a capacitor blows out, then it is probably having a higher voltage on it than it is rated for. You don't say what the voltage rating was for the original capacitor or what the voltage rating was for the replacement. Did you try to measure the voltage in the 10 seconds before the replacement blew??

sounds like a power supply board problem. Be careful. I would up plug it from the wall socket.. the sound u hear MIGHT be something on the circuit board heating up and about to POP. The power supply boards are not hard to replace. just make sure it is unplugged and be careful they can carry a charge even unplugged. Caps etc can Zap u.. as I tell every one , take picture of the insides of TV and the power supply board and a close up of all the numbers that is on the power supply. order the exact same part.. do not remove the bad board till u have the new one ready to go in.. good idea is use a grounding strap. the only cost a couple dollars or so.
Unplug the monitor power cable. You should never attempt to
disassemble an electronic component without first detaching it from its
direct power source.
Remove the screws from the back of the monitor and along the
edge of the screen. Depending on manufacturer and model, LCD monitors
will have screws located on different parts of the monitor's body. Once
the screws are off, use a flat-tipped tool, such as a knife or a
screwdriver, to pry the monitor open by dislodging the two halves; be
careful not to tear wires connecting the two halves.
Locate the power supply unit and take its metal casing off.
Once again, different models of LCD monitors will have the unit placed
in different locations. With the casing undone, unplug cables running
from the power supply to other internal components. Mark the cables that
you unplug from the power supply--you will have to plug them back in to
the new unit.
Dislodge the power supply from its dock. In some monitors
you might have to undo screws that hold the power supply unit in place.
Remember the orientation of the unit as it was placed, because you will
have to insert the new unit in exactly the same way.
Insert the new power supply into the dock and screw it in
place. If you do not have a new power supply, read the label on the
existing one to order a new one from the manufacturer or from a
third-party supplier. Obtain a power supply unit that is compatible with
your LCD monitor; never try to use a generic spare. After installing
the new unit, plug in the cables exactly as they were in the old unit.
Put the power supply casing back on and reassemble the LCD
monitor frame. Gently clasp the two halves of the monitor shut, making
sure you have reattached all cables that you unplugged to take the
monitor apart. Close the casing, tucking away all cables neatly so they
do not get in the way of the monitor casing.
Put all the screws back on. Once done, you should have no leftover pieces (screws or cables).
check the wall plug with another applyance to make sure that hasent failed . Dont laugh but sometimes only half of the wall plug gos bad. If not this you may have a fuse blown out on the inside of the unit. Or the switch may have failed. If its the power supply then you may want to consider a new unit. all tho Panasonic last and last for yrs.
According to the manual for "POWER/STANDBY indicator is blinking in red":
"The temperature inside the main unit has become too high and has activated the protector."
"Promptly switch off the power of the main unit ans wait until the internal temperature drops."
"If the monitor becomes too hot, the overheat protector will be activated and the monitor will be turned off. If this happens, turn off the power to the monitor and unplug the power cord. If the room where the monitor is installed is particularly hot, move the monitor to a cooler location and wait for the monitor to cool for 60 minutes."
(I'm copying a guest's comment above. What Gateway told him does seem to work - although in my case, the monitor was slow to start when plugged directly into the wall, and it was immediately fixed when I plugged it back into a heavy duty power bar.)
hey, I had the same problem. Gateway told me "Plug the monitor power plug directly into a wall electrical outlet or
a different wall outlet by removing any surge suppressors." I did that
and it works. It might be a certain kind of power bar they do not like.
It worked for me so try that and see if that helps.
