When i hit power button light flases a few times but tv wont power up

Greetings Charlotte,

All of the following assumes you are using the TV manufacturer provided remote ...
(ELSE: Get THAT remote, verify trouble & re-post fixya issue)

A few seconds is a really odd symptom (that's an IMMEDIATE cycle (2 power KEY HITS)... so before you rip into the electronic eye (Remote Recvr: tiny board at the control edge of your TV)... and/or change out the main power board...

(think... EVERYTHING else works remotely).

Try:
- unplug your set for at least ten minutes
- close the drapes (block sunlight from TV)
- find the receiver eye & remove ALL close obstructions
- check the remote & remove ALL covers/tape or soil.
- fresh batteries in the remote
- press power button as quickly as possible


Considering (I'm thinking)...

After MY studying HUMAN - MACHINE interface in a lifetime of trouble shooting... I came to know that when people become
VEXED by electronics... they tend to MASH buttons much-more deliberately (this can be a PROBLEM all by itself).

Critical timing on a button press used to be 500 to 900 milliseconds...

Meaning a longer press... went into special "handling" by program code (early software iteration (trial & errors).
((registered multiple KEY HITS = slower response, etc etc))

Your Remote Receiver is designed to register a continuous press (ON THE REMOTE) as ONE KEY HIT regardless of the DURATION... however

Any soil on the set (receiver) or remote (transmitter)...
visual objects, vases, mirrors... even sun-light can significantly change operation... as can TIRED BATTERIES (in the remote).

Failing all the cheap & easy suggestions above comment me back (+make & model) and I'll point you to procedures to get into your TV.

Hope this helps

I just pull out the mains plug for a few seconds then put it back in. The red light keeps flasing for a while (be patient) then stays solid red. When I then switch on again with the remote it is fine. I often have to do this.

It is possible that the button your son stepped on is stuck. If so, remove the batteries form the DVR remote control and see if the TV works. Unplug the TV from the wall for a few minutes to clear its memory to be sure. Some times remote controllers can have cross-talk, meaning it can affect other equipment,

Try putting the cables back where they were. After that re-route them again but this time use the manuel.
If that doesn't work, consult the TV's manuel.

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.

i had same problem today, it had locked up during deal/no deal
unplugged it three times nothing happened, wouldn't switch on
unplugged again left it for 5 minutes
then plugged in and left alone for 15mins plus
lights flasing then evetually green light went
all ok

No, sorry, not from this distance. But if I were actually there, I would try to put the switch back where it belonged, IF it was not broken!

Try it without a code. Turn your tv off. Press tv then press the on.off button and tv button at the same time. When it lights up, press play every five seconds until the tv powers off. Next press the reverse button every few seconds (sometimes takes a while), until it powers back on. When it powers back on hit the stop button to save the code.

That hapened to me once and the solution that worked for me was unpluging the TV for about 5 minutes and pluging it back in, you may just need a new remote though.

i have a simular problem with my sony kvfs120 32, my stand by timer is flashing and the tv will do nothing else. the flasing light is actually a self diagonistic code mine is flasing 5 times.
