Sounds like noise is causing the issue. Could you provide brand and model number?

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

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
After replacement of the power board, Va&VS voltages are to be set according to the silk screen; can be located at the display panel, and it is a must for plasma displays.

LG 42 Plasma has a black Fuzzy Screen when 1st turned on


No, if ANY of the fuses were bad, the television wouldn't operate at all. I suspect that a technician will have to possibly make adjustments to the Y-sus and Z-sus panels to see if that helps. Possibly the y-sus panel is going bad or the plasma panel is going bad itself. Either way you need to have a technician look at the TV for you. Please take a few moments to rate my answer. Thank you.

The PDP ( plasma display panel) is defect.You can look for badly soldered SMD resistors on the COF panels wich are located at the bottom of the screen.
Beware,the flatcables wich the resistors are located on are verry fragile!

How long is a piece of string?

There are 2 boards called sustain boards inside the set. Either one of them or both could be the culprit. Unless you have electronic skill, the right tools and know how to retune the set, I would siuggest this is not a DIY job. Some willsay it is just a matter of unplugging the boards and replacing them, howver that is a short lived fix in a majority of the cases i read on here.

Yes it does work for a while, then other problems arise.. conergence drops out, power fails and a myriad of other things happen that would normally be measured and checked by a good repair technician. It ends up costing 2-3 times more than if it was done professionally. The decision is yours, but i can only advise you NOT to.

Thanks for using FIXYA
