Question about Element Electronics FLX3711B 37 in. LCD TV
Green light says TV is on, but no screen is visible. Cannot turn it off or anything. Must unplug to reset before it will work again. Also, turns off and on very randomly. Sometimes will work fine for days, some days, it turns off and on every several minutes.
In your set, there is a section that receives the IR signal from your remote, then translates the pulses sent and initiates the action you chose.
I think the failure is happening in this 2nd circuit which is now doing whatever it wants.
This section may be located on the main board or could be part of the IR receiver board.
The only thing you might try is this:
- Pull the AC plug and let the unit sit overnight. - Remove the back panel of the set. - Look for any cables connecting the different boards, carefully unplug these one at a time and then reconnect.
If you are lucky, it is only the failure of contacts in one of these interconnecting cables. If there is no change in the behavior of the set, then a component has gone intermittant and to locate and replace the faulty component, you are stuck with either a board exchange or replacement of it. You will have to contact the service company for that brand to get the cost involved with either a repair or replacement board.
Unfortunately, the sets we are now buying are not nearly as reliable and far more complex than the previous generation of CRT-type sets made in countries other than China.
