Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.

New users get to try the service completely Free afterwhich it costs $6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).

If the problem is same with different input devices and you have ensured the are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Screen flickers on and off


If all your other HDMI inputs are out, then I recommend replacing the MAIN PCB
try the following web site: https://www.encompassparts.com/model/ZEN55UB9500UA/_/_/LG/55UB9500UA/55_INCH_UHD_4K_SMART_3D_LED_TV_W_WEBOS
page 4 lists a part number for the MAIN PCB,
HOWEVER, PLEASE MAKE SURE YOU USE YOUR COMPLETE MODEL NUMBER TO ASSURE THE CORRECT PART.

Proscan tv flickering


I'm sorry that the picture on the TV has constant flickering. Please follow the troubleshooting steps and check the operation:



  • Please make sure that the connections are secure and proper.

  • Try connecting a different video source like DVD player or VCR and check the operation. If it works with another device, the issue might be with the input device currently.

  • Also try connecting the device to a different port in the TV if no other devices are available.

  • If the issue persists, try with a different cable.

  • Perform a power resetting and check the operation. To perform the power resetting, unplug the TV from wall outlet for more than 2 minutes and then reconnect it.


Thanks for understanding. Please let me know if you require any clarifications/additional help.

We are having problems with our BRD player BDP s300 playing BRD. It will play regular DVD just fine.


In most cases, the issue might be with the Java contents on the new Blu-ray discs is making this issues. The Blu-ray technology is developing everyday and adding more and more features to the existing technology. Hence it is required to make the Blu-ray Player up-to-date by installing the latest firmware update available from the manufacturer (who ever it is). Going ahead with the first step, please install the latest firmware update available for the Blu-ray Player.
Please click the following link to get the latest firmware update available for your Blu-ray Player:
http://esupport.sony.com/US/perl/swu-download.pl?upd_id=6170&mdl=BDPS300
You can review the "Important Notes" and "Firmware Update Instructions" on the page to get the instructions to install the firmware update.
If the issue persists after installing the firmware update, the would have been with the disc. Check the disc with another player, try different discs with same player.
If the Blu-ray Player is not at all playing any Blu-ray disc, then it may require service.
