HD channels look terrible

hi there.most likely the fuse on the ysus panel has failed,which is the board on the left,looking at it from the back.if the fuse has failed,then so has the board...quite a common fault with all lg plasmas...

A universal remote has a special chip in it that allows it to change the codes for other devices. It should work only on these tvs: DU-42PX12X, DU-42PX12XC, DU-42PX12XD, DU-42PZ60, DU-42PZ60/H, DU-42PZ60H, DU-50PX10C, DU-50PZ60, DU-50PZ60/H, DU-50PZ60H

Hi,

It seems that some parts are having a problem by warming up the temp.
If you're a technician, try some coldspray on the capacitors of the power supply.

Cheers,
Gerard

Another "same probelm"

My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?

Check the controller board, 6871QCH038A. This board is one layer deep into the assembly after the cover is removed. Gently lift the covering circuit board back plane to access.

To do this direct a blast of cold air unto the large chip in the center of the board. If the picture comes back on then you have found it. This means powering the TV while open and this means danger to the novice. Voltage can end your life when you become the circuit path.

Order Part number 6871QCH060Q as the suitable replacement part to this circuit board.

NEED logic control board, model 6870qch003a

LG Plasmas and all plasmas have problems with the sustain boards. You can replace them with just a screw driver to remove back and boards.  Try tritronicsinc.com and andrewselectronics.com and search for Y and Z Sus boards.
They are not cheap and you may want to call a qualified servicer or deal with return cost if they don't work

If it is an older model (i couldn't find anything on it either), it most likely does NOT have a QAM tuner. Be aware that only the "un-encrypted" cable channels will be free otherwise you will have to buy or rent the digital box from the company to get the rest of the regular digital channels. The un-encrypted channels are like 71.2, 83.7 so you should know if you are getting those or not.

You may have to refer to the instruction manual for details.

There should be in the menu set-up an option to set the aspect ratio for the different broadcast modes. Normaly, when viewing a 4:3 picture on an HD 16:9 set, the sides will be cut off, otherwise the picture will be stretched or compensated.

Check within you area for a reliable LG repair center. To fix the problem of the blue, red or green vertical line you just need to replace the control board PN 6871QCH038C. The part cost about $150.00 and a honest repair center should not beat you up to bad on the labor. Good luck and Good viewing.
