SOURCE: Sharp R1420B Totally dead. Power to unit is ok.

Most of these have internal line fuses inside of the casing. Once you remove the housing that covers the top and sides, follow the wires from the cord and they should lead you to the fuse. They are usually on the front rh side looking at it from the front. Be careful, even though unplugged, this unit still stores alot of electriacal energy in the capacitor.

SOURCE: No power

I would guess it's the power unit for the TV itself.

If it's still under guarantee I would have thought you should be able to get it replaced.

SOURCE: No power on LC32D50U Sharp

This is glennac. I figured out what happened and thought I would update for others. The display had stopped working soon after mounting it to a wall mount. I discovered, when I began removing it to take it to the shop, that it started working again once I had loosened one of the mounts screws. Tightening it back in caused the display to lose power again. What I discovered was that there is a spot on the back against which the mount plate rests which, if pressed too hard, cuts the power. Backing the screw out relieved the pressure on this spot and now the TV works again. Facing the back of the display, the spot is at about the 11:00 o'clock position from the center, halfway between the center and the top.

SOURCE: My KP-65xbr10w appears dead no life when plugged in.

If you have no indication of power you may have lost all of the voltages to your power supply, including the 5 VDC standby voltage. I am not sure if you can get a new G board, but you should be able to get the individual components that you need. I would look for the cause of the power supply failure first, and I think I would look at your Horzontal Output Transistor. I am thinking it is Q501, Q401 or something like that. I have repaired many of these and the HOT is most likely the problem. A shorted HOT would cause the power supply fusables to blow and the entire set would appear to be dead.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Thanks for using FixYa

If you have a meter and know how to use it Google for the service manual online and start checking. If not head for a tech or a shop to examine the TV.

A power surge zapped my TV, I turned it back on, it tried to bring up the picture but shut off again. A green light keeps blinking.

if a power surge shut down the unit than a circuit, capacitor or fuse is blown and or burnt and you wont smell that most of the time and since it does have power fuse wasnt blown so a circuit -diode-capacitor is fried somewhere problem is common for an electricial damaged tv but to diagnose an electronic tech would need to tear it apart

My "sharp" tv green power light blinks but has no sound or picture

Likely a power board issue. Check that the caps on this board are blown, and replace with the exact parts. This can be a $10 fix.

Will not turn on, no blinking lights, power coming from cord is good

Sounds like the power supply board is dead. Probably has a blown power line fuse on the board. A power surge will sometimes blow the fuse and protect the board from damage. Replacing the fuse will restore the TV if this is the case. Most times though, the supply has a blown part that causes the fuse to blow and your only option then is to replace the board.

My dell ultra sharp 1702 monitor blinks for quite awhile before starting up when I turn it on...?

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Dell monitors to get some ideas what to look for:

Panasonic plasma th42ph10uk power red light blink twice

Manual says problem with SC, SS, or C boards. SC is large board at left when facing rear, SS is large board at right, and C is small long board at very top. You could check fuses on SC and SS. Also, SC and SS should make a buzzing noise(not too loud) if operating. If a fuse is blown, suspect that board is bad not just bad fuse. Search parts at encompassparts.
