Hello Theboz30,
This plasma might have been manufactured by Chinese manufacturer using LG parts.
This type of failure is normally due to a defective Ysus board and in some cases the Zsus board fails as well.
Please provide the model number of your plasma to help you locate the service parts that are needed to fix the TV.

SOURCE: hitachi plasma tv 42pd380ta problem

Hi, the ysus board on the left side looking from the rear of the plasma has blownup, this is a very common problem with 42PD380TA, if the unit is under warranty you are lucky otherwise hitachi charge alot of mooney for service kit.

I have seen 7 hitachi plasmas in 3 months all with the same fault.
HITACHI dont accept there is a production Fault

SOURCE: Sanyo Plasma Tv Black screen

I had the same problem and Sanyo does not make parts for this model anymore. Luckily I had the extended warrantee so they reimbursed the full purchase price.

Weird that the poster above mine was able to get a part; I was told the part is no longer available.

SOURCE: Black Screen, can hear sound though

My HP PL4260N lost the video portion today . I've had it for only 15 months. It is past the waaranty and HP needs $629.00 to fix it. They know about the problem and yet they do not disclose it at purchase times. It is hard to believe a big name company like HP does that. My next TY, computer, printer or fax IS NOT GOING TO BE HP.

SOURCE: Samsung plasma all black screen

Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike

Plasma flat display


in plasma tvs when the screen is all black the most common fix is your y-sus board. if your tv still turns on ( led in front of tv comes on) and you have all of your voltages coming from the smps board then i would get a new y-sus board.
