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.

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

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.

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.

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
