My tv clicks to come on but no sound no picture


If there was a power outage the problem is likely in the power supply.

The power light on the front comes on or not?

If no power light unplug the set and follow power cord inside and check the fuses---the click is a power relay activating---set may have up to 3 black relays on the power board.

Let me know your skill level and I will be happy to help.

Once the current went out in our residence, the tv went out as well. When the current was restored, the tv didn't come back on by the remote or pushing the power button on the tv itself. Where the green...


Although you may think the power outage has ruined your TV, it has not. I have repaired this model . This model by now has several bad grounds. The worst case is in your convergence board. This problem was in the process before the power outage. I do not believe you will have to purchase parts for this particular model. If you can very carefully pull out the convergence board, you will find 15 or twenty bad solder grounds on the solder side of this board. The major concern will be that the convergence IC, which is a STK-393-110 has separated pins from the board. This would be the first thing to solder. Next the jumper jack cables that connect this board to the other two boards will have bad grounds as well. You must really,really have good eyes to see the cracked rings around the pins of any and all ICs,resistors,transistors, capacitors, diodes etc. This will restore the operation of your TV. I must tell you...it will not be easy to pull this board out and replace. You may opt to see a TV tech. Show a tech this info. This will repair this TV. Thanks for asking and show a few hands of support!

The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.

Flashing green light


Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,
