Question about LG MU-42PZ90V 42 in. Plasma Television

Open Question

Hi i have a lg plasma tv model# mu-42pz90v and the ysus board is bad. The # on the board is 6871QYH027b and when i put that number in ebay it comes up with several boards with the exact same number and they all look identical in the photos to the one thats in my tv but none of them are listed for use in an LG. There are some that are listed for sony, vizio, and zenith but i cant find any that say they came out of an LG. Will one of these other boards work in my Tv or do I have to wait till an lg specific board is listed

If your tv came with a remote, make sure sound is not turned to Mute.

Also try to press the DASP button repeatedly to select the appropriate sound setup to "Flat", "Music", "Movie", "Sports" or "User".

You can also do this from the Sound Menu.

Press MENU button and use up and down arrows to select SOUND.
Then press the left [>] button and use up and down button to select desired sound option. Press again left [>] button and up and down buttons to make appropriate adjustments. Press Enter to save.

Make sure cables for audio is also properly plugged to the right port.

SOURCE: I have a 42 LG Plasma TV with a broken screen

NO....You must pay attention to all numbers on the back of the TV. Verify these with your tech or contact your LG customer support for the correct board numbers. If the screen was broken I doubt if you can repair this for less than it cost to replace. The screen for this one runs at about $650.00. Good Luck and good advice!

Why there is no backlight?


Plasma TV does not use backlight circuits or backlight inverter board. The screen is lit up by PLASMA EFFECT.
You are not getting anything on the screen?

Lg Plasma PC1DA no Picture??????


The provided description is typical for failure of a YSUS board, which is in turn quite typical for LG 42PC1DA and a bunch of other makes and models which all share the same internals.

To find out whether it's the YSUS or the ZSUS board that has gone bad look at the following article:
http://blog.coppelltvrepair.com/2011/02/hp-pl4260n-suddenly-lost-picture-how-to.html

This is for a different make and model, but has the same core modules that 42PC1DA has.

This article also addresses the case when the TV refuses to come on, which is usually caused by a shorted IPM module on a YSUS board which, however, did not lead to burning the fuse as it normally does.
The failure is actually the same, only the symptom is different.

If the failed board is the YSUS (which is the case most of the times, but not always) then you may want to check
http://blog.coppelltvrepair.com/2011/03/how-to-uninstall-6871qyh053b-and.html

Finally, you may consider the following:
http://blog.coppelltvrepair.com/2011/05/should-i-replace-repair-one-or-both.html

Should you need to have one or both boards serviced you can use the following:

Good luck!

I have a LG MU-42PZ90V that was given to me. I found one bad fuse. When you turn the power on it flickers from orange to green then shuts off. I was just checking a few things and noticed that it has...


Hi:

On this model you must replace the power supply if the blown fuse was on the power supply, but the main cause for LG failure is the Y_Substain Board assembly. When measureing the voltage of the Large Capacitors, this is the primary side to the main supply, you must measure the caps form hot ground, on the AC side of the Standby transformer for correct Voltage, 66V is to low. Look at the side of the Lrg Capacitors for their voltage ratings, the Supply voltage to these should be some what near this voltage but never higher. The Y_Substain board is to the left of the power supply standing in back of the unit. Its possible its just the Y_Board gone bad, but in my experience the you should replace them both.

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.
