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. 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.

SOURCE: black screen

This denotes a power supply issue. I would venture to say that it is the part of the supply that controls the plasma ignitor if this is a plasma TV or if this is an LCD screen it is called the back-light and inverter circuit. The power supply board would be the chief culprit in this case.

I hope this helps,

Thank you,

SOURCE: Zenith TV has a big black box in the middle of the screen.

After reading other postings, we figured out that it was the caption box, went to menu and turned it off.
Thanks for the great site, we wouldn't have figured it out without it !

The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

SOURCE: 50 " Phillips Plasma tv. Screen is black, blinking red light.

Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.

Hi,

Thanks for your initial troubleshooting, you've mentioned that the LED light on the right didn't lighted up, that is the SS board(AKA X-sustain board) which is already faulty that's why you've encountered that kind of symptoms. You have to replace this board to resolve the issue. Click it HERE for the replacement. Double check the part/board no of your board before ordering online.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board.

My LG 42LV5500 TV SET suddenly developed problem. All dead, black screen, no sound just power light. All PS voltages are correct.


I would agree with you on that. But it is your money. If the TV is old then replace it, if it is fairly new give it a try.

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.
