The fuse is inside the chassis and likely soldered. Unplug the TV, press and hold the power button for 30 seconds, repeat. Plug it back in and see if that has reset it. Is the outlet good, or did the power outage trip the breaker?
If auto search is going on smoothly, and there is no stations on air is memorized, and display no signal, there are tow possibilities. The first one is antenna is not connected properly. Check the antenna connection for firm. The second one is tuner fault. If the tuner inside the tV is faulty, or it does not gets proper voltage to work, this type of fault land display will see on screen. Check if proper voltages are comming to the tuner section in circuit board. If voltages are ok, and still there is no signal display, just check it with external video input. That is, connect it to any dvd or cd with AV connector, and set the TV to AV mode and play a disc. If there is picture, the video side of your TV is OK. If not, Video-chroma-RF jungle IC is faulty, and not the tuner. OK.
Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.
this is your over current protection B+, there is a short in the power supply of many of the circuits,fuse,diode,etc, check these carefuly with ohm meter....if fuse is open,only replace it with the same rating,make sure tv is not pluged into outlet...if you need to replace parts,use a desoldering iron,to **** off the solder at pin hole of the part being removed from under side of board also look for burnt spots,then you need wire wick to remove and clean in and the pin hole. reinstall is reverce order,,maker sure you make a good connection,and not over solder it ...keep it clean.hope this helps...........
Turn off the television. IMPORTANT: For
a projection television that uses an internal lamp, wait 5 minutes
after turning off the television to allow the lamp to cool before
continuing with the following steps.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet. NOTE: If
the television is plugged into a power strip or surge protector, remove
it from the power strip or surge protector and plug it directly into
the wall outlet. If the issue is resolved, the problem is with the
power strip or surge protector and not the television.
Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
Try the 60 seconds unplugging of wall plug in your outlet. Or check your line if this have surge protector. Temporary plug your unit to wall outlet directly. Just check if it still within voltage operating range.
first make sure that the plug of the tv-device is well pluged-in and the voltage in your home is normal.if all this, is ok ,enter in the menu and check the status of `timer sleep`(if `on `than turn it `off`)
Any sound? If so, it could be a bad display or high-voltage or associated problem.
No sound and no picture could be a bad line cord, power switch, blown fuse or AC problem.
In this case, make sure it is plugged into the ac outlet and the ac outlet is getting power by plugging in a lamp that is known to work into the outlet. If it does not light, then ther is no ac power at the outlet and you have a bad fuse or tripped circuit breaker (most likely) or (less likely) a faulty outlet or break in the house wiring.
