These boards are rarely if EVER "repaired" but are replaced.

Google the model number with "parts" to find the part number etc--a few dealers (NOT LG) carry and sell most or all of the boards with lists by model number---be aware that LG often used a bar code label on each board---some of the venders will list 2 or 3 parts with different numbers.

I replaced the module on YSUS board and replaced the FS2 fuse on hp cptoh-0602 plazma tv. TV worked great for about 2 hrs of usage time. however, while i was changing the channal few days later since...


Usually, when you replace Y-sustain board, for older plasma, they suggest to replace both Ydrive board (up and low). And sometimes, Z-sustaint.

Im not sure your are an expertise in this matter so be very careful when you open a TV because hasardous voltages can kill you in the worst escenario.

If you are not, don't work on your TV. It will be your sole responsibility.

Check ships on Y drive board (both board are installed on the right side of Y-sustain. They have square black ships that used to get bad. If they don't have aluminum cooler on them, you can see if they are burned or have holes on them. Old plasmas use to have issues with those boards. Before you installed the Y Sustain you should check Ydrive boards. Maybe you damage the Y Sustain because the Y drives weren't good.

Try to replace the fuse, disconnect the Ydrive from Y Sustain, turn on TV and check for voltages on Y sustain (panel has a sticker with each voltage). Hope you didn't damage Y sustain and can find Ydrive board to fix your TV.

And REMEMBER, you can kill yourself when you work on TVs.

I Have an LG RU42px11 that displays dark fuzzy screen. I replaced both the Y sustain and Z sustain boards, but stiil the picture is fuzzy;moreover, the new z sustain board just blew from a C3 with red cap...


Send all 3 boards to coppell tv repair (http://www.coppelltvrepair.com) and pray.

After having invested time and money your real question is "do I continue with this or do I cut my losses and leave".

We can test all the boards and we can usually repair them too.

Knowing the price you'll have an easy choice as to whether you want to go ahead or bust it.

For a TV this old I can't honestly advise against busting.

But I can honestly say that if you're to bust it then at least we can have the bad boards and maybe help someone else in your position who's not going to bust it.

I can't comment much on what you;ve done because without seeing it I'll have to make lots of assumptions.

Dark/choppy screen can be caused by both YSUS and ZSUS by the way. Most often it's by the ZSUS.

Hello williams6590,

Welcome, and thank you for using FixYa!

Your problem is the X-Sustain Board. There are a large number of componants and connections on this board. I recommend purchasing it from eBay! and then having a TV Repair Professional install it.

Here is a link to purchase the part:

HI I HAVE A LCD 42" LG TV< AND AFTER 3 MINS OF TURNING IT ON I HAVE NO PICTURE BUT SOUND IS WORKING PERFECTLY HELP???


Hello,

no picture and sound is OK => The problem is from the
Y Sustain problem. However, normally they have to change both Y Sustain and Z Sustain boards at the same time. If you lucky than it's just a fuse on the Y sustain blown (the chance is very rare) otherwise the IPM (Intelligence Power Module) on the Y/X sustain board is short. This is a common problem and costly repair for Plasma TV.


Hopefully, it's something simple to replace like the fuse.

good luck in solving the problem and be careful in handling it, because the Television is fragile and contain high voltage in power section of the power board...

If I have to replace the Zboard LI4101199A what would something like this run? My unit is 7 years old.


if you are replacing the X-Sustain / Z-Sustain Board yourself,
the part is 179.95 + 10-15 s/h

if you are taking it to a shop for repair, it is easily going to be double that.

This condition, sound no picture, is generally a result from a failed y-sustain and/or x-sustain board. You can check the fuse for continuity or resistance using a multimeter. I am helping someone repair their LG 42pc3d, that's why I thought I'd help you out too.

No video but audio is fine on Sanyo 42" DP42746 TV


If you unplugged the Ysus board, then you need to replace the Ysus board, or both sustain boards. This is the part: The part is often available on Ebay, or from manufacturer. Look also at Vance baldwin or Partstore. To do a good job the Sustain boards should be tested by a tech , following service manual. It is almost for sure sustain board by the way.

I have a Zenith 50" Plasma. I was watching tv, then heard a load pop and the screen goes black. I have power and sound, but no picture. What's the deal?


If this tv is 2-3 yrs pld, your problem is going to be you Y-sustain board or your Z-sustain board. This is a board level repair unit. These boards usually cost about $300, give or take.

Plasma sets do not have an inverter panel. Your problem is either the power supply panel or the Y-Sustain board. The power supply in some areas can be repaired, if it can't, it would probably be around $150.00 for the board. The Y-sustain board could run 3 times that amount.
