Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

the regulator for the Inverter supply would be the first thing i would suspect if the voltage drops then picks up again. Then I would also check the transformers on the Inverter that are in line with the area of the screen that flickers.

This is noise from defects in circuit. First of all try using a different input device such as a DVD player. If problem persists, please refer it to a qualified service technician.

You need to give a more detailed description of the problem.The LG 47LH90 is an LED backlit TV with 'local dimming' technology. This means that there are lots of white LEDs behind the screen and these can be controlled in groups to allow localised areas of the screen to be dimmed to produce better contrast between light and dark. It is very likely that when the room is dark, this local dimming is more noticeable. The actual individual LEDs cannot be controlled and so the area that is dimmed will generally be greater than the area that is required to be dark 'blooming effect'. In addition, LED backlit displays only maintain their contrast through a tight viewing angle. If you sit too farto the right or left, then light from non-dimmed LEDs will leak through and the screen will look lighter.In short, there may not be any fault with your TV.

Hello
Connections with DVD-TV is of main concern. For HDCP connections, very high quality cables [like Monster Cables] should be used. There is special type of cables to connect to HDCP. The length, wire guage, shield of these cables are of special types, and signal loss will be negligable. Connect the TV with DVD with good quality cable packed specially for HDCP. This will solve the problem. OK.

please refer to this picture: http://www.retrevo.com/r/375bh427/3/Connections+for+your+VCR#q=Zenith+VRB4215

Rather than use the method in the picture above you should use the audio L+R and video OUT on your VCR and connect these three to the color matching audio IN and video IN ports on your television. The colors are red, and white for audio and yellow for the video. If you do not own a cable like this simply pick one up at radio shack they will know exactly what you need. The pictured method will work also but the picture and sound quality will not be the best possible.

Remember you are sending data OUT from the VCR and IN to the TV

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

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 ..

This is the Power Board for it. check those 6 electrolytic Capacitors on the right for bulging or splitting. Don't buy it blindly, it's a guess. The output voltages with a digital multimeter. https://applianceparts.com/item/10217204/LG/EAY62812602/ Many parts are obsolete. eBay has used boards, but they are risky because they are out of scrapped sets. https://www.google.com/search?q=50PN5300-UF+power+board We have a television expert named Larry, but I haven't seen him for a while.

Maybe the disk is not compatible with the DVD player version

It can't be done. The DVD remote will be single frequency for that device only and the LG remote for that LG Blu Ray (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television. If you have lost a remote or it doesn't work, this is the answer https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..
