unplug tv, take batteries out of remote. plug tv back in, replace batteries. best idea i have. sometimes that resets the devices. good luck

I just had this same issue. I tried to change the batteries for the factory remote that came with the Onkyo HT-S3500 (remote: RC-799M). Still no luck. It would not power on with the remote, despite the light flashing and the and all other remote function working. If I powered on the receiver manually, everything worked (except power on/off).
I just pushed a button on the remote labeled "REMOTE MODE RECEIVER" and viola, the remote now powers the device on and off and works just like usual. Not sure what the heck happened, but I would suggest pushing that button on your remote.

Hello, the most used buttons can wear out over time. On/standby and volume are the ones that are used most often. I suggest purchasing a new remote. It is available at shoponkyo.com. Thank you, Onkyo USA

Yes the VCR remote sensor is faulty. It will most likely be the IC, which can be found by tracing the wiring from the detector on the front of the vcr.

i was programming my television by hand because i do not have a remote to my television and i accidentally set the child lock and now my tv will not turn on what can i do to fix my tvtv is on standby, standby light is on. can turn tv on with programable remote after pressing on button several times to set code on remote. press any function button and screen says child lock is on. can't get anywhere pressing any buttons, turn tv off with on/off button and tv goes back to stand by. don't have magnavox remote any ideas?

take the batteries out of the Sharp remote press and hold the POWER button on the top of the remote for 5 seconds. Put batteries back in. Make sure that function is set to TV. Should work - if not call Sharp. If you are inside the original manufacturer warranty they will replace remote

have you tried changing the batteries just to elimate this problem

change them

sometimes if the batteries are low in electronic devies, they send a wek signal to its receiver (your tv),

your tv gets confused and then switches itself to standby

if you have changed the batteries and this problem still persists

it can only then be th PSU or power supply unit, take it to your local tv repair shop of mastercare somewhere like that, its going to be cheaper to get it repaired than replacing the whole tv

PSU'S generally 20 to 50 pounds depending on model

don't deo it yourself though unless you've got a capacitor discharger (or a nice 25KV will be on its way to your body)

hop this helps mate, let me know how you get on
