Hvis TV-en din ikke tar imot signaler til HDMI-inngangen, kan det v?re flere ?rsaker til problemet. Her er noen feils?kingstrinn du kan pr?ve:
Kontroller kabeltilkoblingen: S?rg for at HDMI-kabelen er ordentlig tilkoblet b?de TV-en og enheten du pr?ver ? koble til. Pr?v ? koble kabelen til en annen HDMI-port p? TV-en din for ? se om det gj?r en forskjell.
Pr?v en annen enhet: Hvis kabelen er tilkoblet riktig, kan problemet v?re med enheten du pr?ver ? koble til. Pr?v ? koble til en annen enhet, for eksempel en spillkonsoll eller en Blu-ray-spiller, og se om du f?r signal.
Oppdater TV-programvaren: S?rg for at TV-programvaren er oppdatert til den nyeste versjonen. Du kan sjekke dette i TV-innstillingene. Hvis programvaren ikke er oppdatert, kan det p?virke TV-ens evne til ? gjenkjenne HDMI-signalene.
Tilbakestill TV-innstillingene: Pr?v ? tilbakestille TV-en til fabrikkinnstillingene. Dette kan hjelpe hvis det er en programvarefeil som forhindrer TV-en i ? gjenkjenne HDMI-signalene.
Hvis ingen av disse trinnene l?ser problemet, kan det hende du m? kontakte en kvalifisert tekniker for videre feils?king og reparasjon.
If the LED backlight strips were new and you have all the connectors seated correctly it has to be a power board issue, or more specifically an issue with the inverter section of the board, remember its the B- section that is regulated not the B+, start by testing B+ to frame ground and see if you see 100+ volts on both circuits, next test the ripple, I've seen the inverter caps fail on this model a few times, other option would be replace the main board but I'd pull the panel out again and make sure all connectors are good, you can power the set up with the panel out but unhook the panel at the tcon not the panel to be sure the connectors don't short to the frame when it's powered up.
Hi,
Please double check that you've haven't used your remote to remove the display. Some remotes have a "visual mute" option. Also, please ensure that you're tuned to the correct HDMI input. If you accidentally changed it, you might have moved to an hdmi channel or state that has no input.
Thank you.
Take the batteries out of the remote, pour boiling water from the kettle, dry them and replace.
CC BUTTON, Credit Card, Closed Caption? Abbreviations don't work.
Did you know typing in all CAPS is considered SHOUTING and very rude, plus it is harder to read.

It's possible you damaged the tcon. When you connected the ribbon connectors going from the tcon to panel boards you may have damaged the tracers, remove the connectors and see if those are bent or broke off. Another possibility is the panel was damaged when it was handled, you need to use static protection when handling the panel, if this wasn't done it could be damaged
Ebay has a refurbished main board for $67. Your Vizio may have cost about $800. And you are thinking about a $2700 TV?
If the Vizo died and went to heaven, would that prompt you to buy a $2700 tv? I don't see that the potential ***** of an $800 TV has anything to do with a decision to buy one that costs three times more. If something went awry with the $2700 TV, I pray you would use the warranty and not dive into its interior workings. My thinking is that if you are of a mind to buy a $2700 TV, you wouldn't mind spending $67 on ebay anyway, extend the life of the Vizio, and have two TVs. Nothing about the lifespan of the Vizio forces you to spend $2700 on a TV. If you paid $67 for a mainboard and installed it and it lasted three weeks, nothing would stop you from buying another Vizio. The only thing lost would be the dream of owning a $2700 TV. So, the question is can you live without the $2700 TV. And what would the purchase of such do to your budget as Christmas approaches. And would a $2700 TV make your life $2700 easier? Only you can answer that question.
The cables might be loose or not connected tight enough or the cables need to be replaced or the screen has damage to it or the Tconboard is not working.The theexternal device might need to be repaired for your TV.
Your LED backlights most likely have failed and need replacing, it's a common issue with this and many other model LG sets, new strips can be purchased from shopjimmy.com for around $60
This positively is a capacitor issue, when the caps are cold, they lose capacitance, if you put a blow dryer at the vents and warm the set up I'm guessing it will power on first time. I'd replace all the caps in the power supply section not just the ones that look or test bad
There might be either a cable that is loose or not connected properly or there might be a problem with your TV's hardware. I would try to first re set the TV by unplugging it and everything else that is connected to the TV for about 1 minute and also press and hold the power button for 30 seconds too and wait a couple of minutes to plug the TV and everything back in.
Hi,
Please plug your rca(?) plug into the corresponding color-coded plug(s) within your JVC device. And if those don't exist, then you can check for an amplifier plug.
Each cable should fit comfortable into it's intended slot.
Thank you.
The T con board is not working correctly with your TV or the cable connections are either broken or loose or the external device are not attached fully to the TV. Or the wiring is not been connected properly.
Well you have covered the main two, overheating and failing capacitors. The only other one I can think of is a component / IC dry joint on the circuit board. As the board heats up, the connection fails. Or something is failing internally when heating up.
