Question about Zenith Televison & Video

1 Answer

I have a Zenith Z50PT320 plasma tv. After a few minutes the picture turns very posterized and flickers. Should I replace the Main Logic CNTRL T-Con board?

When I turn on the picture is fine. After a few minutes the picture appears posterized (loses its color range) and begins to flicker.

SOURCE: Red noise or flicker on bottom half a plasma screen

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.

Hi


Thanks for using FixYa. As you have already replaced the Z-sus and the main logic board then the issue seems to be with the Y-main and/or Y-sus board. You’ll need to take the back off and check for any blown/bulged capacitors that might have gone bad and causing this issue. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

Are you sure that its the main A/Vboard coz it sounds like the main power supply issue to me. Anyways the mainboard is the large board usually located at the center of the tv. If you can remove the back cover of the tv and get me a high res picture of the tv I can mark the board for you.

Samsung has standby light, it blinks tone sounds no green light. Replaced t-con, power supply and control boards.


Hi Patrick,

have a close look at your LVDS cable and screen ribbons for signs of failure or heat damage, and you could try to pull a picture from an AV output in various formats to see if it's the screen itself is failing in some way,

regards

What does is mean when black flickering lines from top to bottom of screen appear when i first turn my samsung 50' model un50f5500 HD plasma tv on but goes away after a few minutes


It sounds like either your main board or logic board is going out.
You might want to check the capacitors on your power supply also. If they are swollen they will need to be replaced. Swollen caps can cause video distortion until they build up a good charge. Good luck to you.

Ok t-con board is connected to main board which is giving signal and logic supply.. If the main board failed or giving a over voltage to the t-con it possibly your T-con gone out (new) again.

To isolate the problem try to replace the main board.

I have no sound from Xbox HDMI connection.


you likely connected it with one or both units involved on and HDMI does not like that--prone to all sorts of audio issues.

If in doubt unplug the units and wait and plug back up making the connections first.
