Defective Power Board. I replaced mine today but I have some experience in Electronic. Cost 180.00.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, 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, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

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

Unplug,replug should be back to normal,not than U must change the power supply.

check the trouble shooting guide in the manual that came with the TV.

Do you have this problem on both HDMI inputs? If so there will be a problem with the software that recognises the HDMI signal. If it is only on one HDMI input, then there will be a fault with the socket. Either way the only way to fix it is to contact your dealer & arrange a service engineer to call,

If the repair shop says it is powerboard it means they already took a look at the TV and you dont need to worry about it.
If you have any doubt please post the sympton here (detailed) and I can tell you for sure what the TV needs.
I need to know what the led does and how it does.

USE RCA CABLE SET IT IS YELLOW/RED/WHITE THE YELLOW SHOULD BE VIDEO IT WILL SHOW THIS ON SET AND PLAYER. I WOULD ALSO RECOMMEND YOU USE THE AUXILIARY PLUG IN ON SET THEN JUST TURN ON SET AND SET TO AUXILIARY IF YOU DON'T HAVE THIS USE DVD FEED IN THEY SHOULD BOTH HAVE RCA PLUG INS FOR RCA CABLE

Your right its a power supply issue and what your hearing is capcitor pop or maybe even a fuse, Well if you know about eletronics sure the new psu is going to be $150 bucks

hope this helps Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

It is all plug in. The only thing you MUST do is using a digital volt meter is make sure your VS,VA voltages are exact to the label on the top of the display panel. If you don't you will wind up with catastrophic failure of other boards in a very short time. They must be set set to a pure white screen.

The mainboard need to be replaced, the price should be something between $80-$120.

Hello jmaselli1,

The popping sound may have been a capacitor or a rely. I am going to assume it was a capacitor, since you probably have not heard the popping sound since that first time. In the case a capacitor possibly located on the power supply board has vented and caused a short circuit in your TV set.

To answer your questions:

is this common problem? yes it is due to a strange case of industrial espionage on the capacitor makers part.

expensive repair? Not really if it is only one bad capacitor, if there are others it could get expensive. depending on the labor costs

I hope this helps,

Thank you,

sounds like it may have blown the color tube. time for a new big screen hi-def tv

there is a problem with the firmware. Firmware is software and hardware for a tv. The two are conflicting with each other. THis is usually cause by a bad capaictor that is sending out the wrong voltage/reading. It will have to be tested.

HI, this will happen when the power isn't distributed correctly, in return, depriving the main board of its needed current for operations. this will usually produce these lines. Replacing the power control board will fix this issue. LG Electronics/Zenith Part Number: 6871QYH039B

Mainboard damaged and need to be replaced, try EBAY for a general picture of prices but you will need your product code wich is located in the back of the TV next to serial number.

Ok, you stated that you get a green for a second and then a couple of blinks and then, it turns off. This rules out the power board but, its main control partner is experiencing some trauma. Normally in the plasma TV set, the green is a go but, if the PCB(Power control board), doesn't agree, the the power board will shutdown the entire unit after giving a few blinks. Its very important to remember that, the power board and the power control board are two separate circuit boards. In your case, the PCB is down and it will need to be replaced.

Please rate and god bless.

Clean the Lens: Use a DVD cleaning disc to clean the lens. If the problem persists, consider professional cleaning. Test Other Discs: Try playing different DVDs to see if the issue occurs consistently. If it's specific to one disc, that disc might be the problem. Check for Updates: Make sure your DVD player's firmware is updated. Refer to the manufacturer's instructions for firmware updates. Try a Different TV: Connect your DVD player to a different TV to see if the noise disappears. If it does, the issue might be with your TV. The hum is simply the player trying to read the disc. It can't so, it spits it out. Remember that prolonged use of a malfunctioning DVD player could potentially cause damage. If the problem persists, consider seeking professional repair or replacement

Question edited for clarity. It appears to be an LG rather an an IG. https://www.avforums.com/threads/lg-42lb1db-how-cani-remove-the-swivel-base.519459/ Further Help and videos https://www.google.com/search?q=lg+42lb5df+remove+base+stand ..

The screen blank out

Likely a dry connection where the HDMI socket it soldered to the board. https://www.google.com/search?q=LG+PLASMA+TV+MODEL+NO.60PS60-UA+that+is+not+picking+up+the+HDMI Old plasma technology though, time for a new one, as quality has moved on. https://reviewed.usatoday.com/televisions/content/lg-60ps60-plasma-hdtv-first-impressions-review-830 ..
