SOURCE: tv turns on but no picture just a red blinking light stays on

Red light blinking means there's a problem in the TV....

What kind of tv is it?

SOURCE: 42 LG plasma no picture but sound. found internal

Sounds like it started "Protection Mode" because of a failed electronic part inside the TV. When this happens, the TV will keep turning itself OFF or will not turn ON at all. This keeps the other parts inside from being damaged. Most likely the TV has a power supply related problem. The common part to go bad for flat panel screens circuit board that powers the screen itself. Most manufactures call it a Backlight Inverter Board.
But, I can't say what is 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.

You have a few choices:

1. Best thing to do, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, schematics, test points, and part# lists.Usually, cost under $20. Its the best repair guide material for fixing TVs. And most cases the new part cost less than $15 by searching on the internet with the part number.

2. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Who are "THEY", will "THEY" pay for the parts if the problem is not fixed with the two boards? I would not listen to them, have a shop that knows for sure repair the problem.

LG 47LV5500 UA.AUSYLUR power board problem likely,,set won't power on


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

OK.. it seems i'm not having a lot of luck with TV's these days.. i have a LG 60PS60-UA plasma TV that won't power on. when I do i get a red light where the white light normally is when working corre


Hi, It also could be the inverter board(s) that have gone bad. Check them out. If the inverter board goes it will also turn the TV off.
These boards are on the left and right sides of the TV pannel.
Good Luck with your repairs.

LG shows it will lose display in 3 seconds


hi the tv has detected a fault with the back lighting, now it could be a problem with the voltage to the back light or some of the leds in the back light have failed, it will turn off the back light when it finds a fault. behind the screen there is rows of leds on strips and they all light up when the screen is in use. and the main board knows they are lighting up by the voltage its using. when to many leds go out the voltage is too high so it will turn the back lights off to save them. also the same if the power board is not supplying the right volts. say the volts need to light the back screen is 64 volts and its only giving 62 volts the power is not right so it shuts down. same for if the volts go up to 64.5 volts it will do the same. hope this helps you under stand.

We have a 2007 Sony Bravia 46" KDL-46VL130. There is not sound or picture. When we power it on the green light comes on blinking once and then the red light blinking once and then the green light stays on....


Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

No picture, only sound on LG 47LV5500: how do I get picture back?


Definitely odd for sound to come through and not sound, especially via an HDMI connection.

I would contact LG for support, your TV could be defective.

Good luck
