Hi Guys,
Can anybody comment on were they think the fault is with this plasma from the attached photo?
Thanks.

Re: LG Plasma RZ 60-PY10
Most likely cracked solder joints on the COF resistors.
The COF are at top and bottom of panel, and run the length of the panel.
There may be burn in where the parts of the image did not light properly.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: LG Plasma RZ 60-PY10
Thanks Tom.
Should I only be looking at the cof chips at the top of the panel as the lines are at the top of the screen? Is it possible to resolder them?Last edited by blib; 11-11-2013, 01:09 PM.Comment

Hi friends,
This is my first post in this forum and I hope I would fetch some of your valuable time
Let me brief, long story short..
I am working on an LG plasma TV model 42PQ30R.
The fault is no display.
The tv is turning on, the blue led is working, however there is no standby (red light), tv automatically going in run mode (i.e blue led)
Note: sometimes gets off automatically but it happened only once or twice.
I began my troubleshooting with the power supply, all fuse ok.
power supply ok, getting the required panel voltages... -
Hello everyone. 😀
As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.
Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
There are no devices that have exploded or otherwise show signs... -
- Prior owner tried a replacement main board. No difference.
- Samsung 2x red blinking standby LED = panel fault
- Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
- Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
- Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not
One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference... -
I took a look at a television for a friend, it has some serious image fault. I don't know what the cause is or if such a fault is even repairable.
The T-con board seems to be integrated into the panel so looks even more annoying to work on than normal.
What's the most likely cause of this problem, does anyone know?...
