Hate to give you bad news but this sounds like panel issues. You could try a tcon but I seriously doubt it will help

Check the color mode set to Auto Mode

If any buffer board is faulty, this kind of fault can occur. Might have a panel fault too. It will be best to contact any service technician, to make it confirm. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

The Z-Sustain should be suspected. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 1200 posts to different brand TVs now. Pull up older posts there. Faults to almost all brand Plasmas will be the same as they are all built on similar chassis. Refer any one. You can get details.

I have the same problem. since I have 3 of these TV's, I switched boards around, and I came to the conclution that is the power board. I will try to repair it, and I'll let you know the component that is bad. Gaston

Hi you have a bad sustain Board. Either the lest or the right sustain board is bad. You can get parts for this TV at www.interliquidparts.com

Hello,

first, make sure the TV is correctly plugged into the wall. You can try another outlet. If that doesn't work, then your TV is certainly having a power problem.

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on......

All these can be checked on the power supply board.......

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes).

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.......

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

Yours sincerely.

Any tv repair shops,look for them on the telephone Yellow pages.U mean litterly the power supply board taken out of the tv unit,yes,if they except the job.All tv shops,like their customers keep their parts in the tvs,Some charged u to come out and have estamate for the cost for repair some don't charge just look at the problems to telling u.

Unplug,replug tv back in an hour later.Tv now reset it self back to factory setting.Now it should work.Not,than the power supply board is dead.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

U check the channels display?Anythings less than 1080i is standard def channels.

Power supply. Contact Vizio support, and they can point you in the right direction.

the VizParts people are the official parts suppliers, and they also have better pricing than anyone else on the web from what I've seen.

Swapping the power supply is pretty easy.

I have seen the caps in the power supply vent, which means they get hot and the top pops up and splits open, resulting in the "bang" sound. If you have experience in electronics then remove the back of the set and examine the power supply, looking for any caps whose tops are bowed upward, and replace.
