Tv won't power up straight away - Wharfedale LP160DTRHDMI

Is there fuel in the tank?

It seems that the set itself changes inputs. Place it remote control away from the vicinity of the tV. and check. If it does the same, do a hard reset next. To make it a hard reset, unplug the TV from AC mains wall socket, and replug it back after 10 minutes or so. If these do not help you, be sure that the main system control memory IC to it is faulty and should be replaced.

Hello!
First move: unplug your broadcast provider's box, wait for a minute, then plug it back into power source. I mean: leave all the connections intact, just unplug from power source. It might be just power cord or power adapter. If that's not the case, please do the same with TV. Unplug it from wall outlet, wait a minute, plug it back in. It's a next step, if your "box" won't take care of the problem. If that won't take care of the issue, refer to owner's manual for "reset" procedure. Worst case scenario: you might need to replace main board inside or your TV.
good luck,
Thanks,
Alex.

I had the same problem with my E7, if you've already tried holding the power button down for 10 seconds then you'll need to remove and replace the battery, that fixed mine straight away. Just follow the guide below

You did the opposite of what might be useful. Completely cut of it's AC supply, pull the plug out of the socket and leave it like that for 10 minutes.
Plug back in but first making sure the manual power button is off on the set, not in standby mode.
(pushed in)
Then push the manual button to restore standby mode and switch set into full on mode with the remote.
It will either have "rebooted" and work straight away or you'll need to put it into Auto Set Up mode.
Proceed as the first sections relevant from the instructions.

This is easy ... it is still under warranty ... take it back ... do not do anything to it as you will void your warranty.

Take it back straight away and have it repaired or replaced.

Simple

Thank you for your interest in FixYa.com

Hi

you could try this

press the power on key
then straight away tap the alt tab bottom left along with the F10 tab top right

so its

power on
Alt+F10

this will hopefully take you into the factory recovery options
and choose what you want to do
then follow on screen instructions


hope this has helped you
please let us know if it did or didnt
so we may be able to help others

Yes the display settings need to be reset since he had HDTV and you don't. I do this by simply having the PS off then press power button and hold it for 5 seconds.

Hello
Just switch OFF the set by its front panel power control switch, and then switch it On and press the eject button without any delay. Sometimes the tray will eject, and try to close. If so switch OFF the front panel power switch, while it is out, and take away the blu-ray disc. the switch it On. All will be ok then.

Have you looked at the manuals?

A TV won't run external speakers directly. Besides, the TV-related audio should originate at, say, the cable Box, and go straight to your (presumed) AV receiver for the best possible decoding and reproduction.


Buzzing is an analog phenomenon and is NOT carried by optical cable in any case.

Buzzing is usally AC line noise leaking into an un-shielded cable somewhere or a floating ground. If the AC plug is reversible, try that. Sometimes the buzz is from an attached device. Make sure all audio cables are plugged in tightly at each end and routed away from or at right angles to any power cords and away from other sources of strong magnetic fields like TV's. I've also seen variable track lights induce noise but it's usually minor.

Try rotating the power cord in the wall outlet.

If it still buzzes with no cables or anything external attached there's an internal problem.

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

Reverse the cables Left to Right to see if it stays with the cable or the input channel. Follow it back to the source, isolating in the same manner. Eventually you will find the entrance point of the hum. Frequently a cable's ground will oxidize over time and simply removing and reattaching the cable with a twisting motion will re-establish the shield.
