Y Board is out. The boards costs about $150 and easy to install.

The part is $75 as you can see here http://goo.gl/SolI1 and the price for the one hour labor to fit it in is $155 - quite steep but not excessive: a decent labor costs would have been $100 to 120.
So the total price is still acceptable.

I have the same tv doing the same thing any help out there

Good day!!!


If you think the Y-sustain board on your plasma is bad..

you can replace it on your own...

Y-sus is a hand insert board. There is no soldering required.

Follow this steps:

1. Just remove speakers and stand.
2. Then take out screws holding down back panel.
3. You may need to remove supports inside, just remember what order you do so. take out old y sus and put it new one. simple.

I hope this information will be helpful...

Thanks for using fixya...

Backlight inverter. These range from $50-$150, depending on where you buy them from. Check shopjimmy.com or Ebay even. The replacement is easy. Out with the old, in with the new!


Thank you and best of luck!

Try to unplug the cable and the TV for about 1-2 minutes. Then plug it in. Turn on the cable first, wait til its on then turn on the TV. it should work.

If you are sure you have plugged it back up properly then you should at least get an indicator light on the front. And be sure your wall socket has power. If you have no indicator light at all on the TV then it is likely to have blown a fuse, and especially if you hear no click or sound when trying to turn on. Trace the fuse from where the AC cord goes in. Of course you will have to take the back off the set. Put the same amp fuse back if it is blown. I check fuses with a contunity checker, however simple replacement is fine and can be plugged in a fuse holder after taking the suspected one out.

surely there is problems with the lcd controller... you need a qualified technician to check the power consistency in your lcd controller.

your zsus board is failing replace it and the fuzzy screen will go back to normal

The loud pop and the picture going out is usually due to either failed buffer boards or sustain boards. The first thing to do would be to examine the sustain boards for any visually identifiable damage.Have a look at the boards titled X-main and Y-main and see if you can notice any charring or anything of that sort, especially near the fuses. If nothing then let me know and I will give you instructions for testing the pico fuses.

Hi,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Hoping this will help in solving the problem....

Did you try buying a new HDMI cable? You can also try some of the solutions in the post called "Hp 42 plasma tv cptoh 0602 I get sound but no picture."

HP sold this TV with a bad board and they knew it was bad but still sold the TV's anyway. Our group is taking action to protect consumer from this type of corpoarte greed. Contact us: [email protected]

Same here and all my questions and HP support says Y sustain board. Everyone is saying cost of board is $150.00 But I found one for $60.00. But u have to be electronically savvy or it will cost 629.99 thru HP. www. tvboardbanks.com is where u can get the rebuilut board. Or there is a place in Bloomington In you can send ur board n and have it rebuilt. $122.00 plus shipping and handeling. I have to find the nake of this place again.

You would need to contact a third party vendor for this fuse. Hp would have them but there going to most likely sale it to repair shops so you might want to check into a repaire shop and ask to buy one.
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Ur LCD inverter board it dead,need it replaced.

I had the same problem today, Hp wanted $629+tax to fix. With a little mechanical ablity anyone can fix this.
1. remove back covers
2. left-hand side is the video board
3. two white fuses
4. replace

this fixed mine and they only cost $1.50 each

First things first:this is a common and actually guaranteed problem in all 42'' TVs that use the same LG display technology.
I'd take it a step further and say it is a common problem of pretty much all plasma TVs made in 2004-2005.
And there's A LOT of them.

So while you can blame HP for failing to support a product released under their brand you also have to understand that the problem is deeper than that.

We have serviced easily hundreds of those boards and we have sold hundreds of DIY repair kits so I know what I am talking about.

Both the Y and the Z sustain boards (6871QYH053B and 6871QZH056B respectively, or some of their equivalents) use the same intelligent power module (IPM) IC and it is unfortunately designed to work on a very high temperature.

It works all right, but it also wears out.

If you have ever wondered how does a semi-conductor wear out just think of it this way: you know how steel is hardened, right? Hot - cool - hot - cool...the process changes its structure.
The very same things happens with semiconductors, except unlike steel rods you have a zone think in nanometers range that expands and shrinks thanks to temperature differences.

It can only take so much and it eventually changes properties enought so that one day there is no semiconductor anymore. It's a conductor.

It busts and you get the problem you describe.

One very simple and essential conclusion is that ALL plasma TVs that operate at high temperatures, in fact ALL appliances that operate at high temperatures, face this problem. Of course it depends on how thick the semiconductor junction is, how was it created, etc. etc. factors that determine how many times it can withstand expanding and shrinking before it loses its qualities.

A second and more practical conclusion is that since the same component is used on both sustain boards you are going to have the same problem on both!
And this is exactly the case!

Don't have enough space here, so if interested, read the rest at our site.

Hope this helps.
