@csew004 start off by checking your TV with the PDP panel self-diagnosis function
This function is for a PDP panel failure with no picture.
To enter to this Self-Diagnosis mode, follow the next steps:
Preparation:
1) The Power Cord should be connected to AC line and the Main Power switch should be turned on.
2) Turn the power off by the SUB-POWER button of the monitor or the remote control.
Procedure:
1) Press the SUB-POWER button and ▼ button on the bottom of the monitor at the same time, and keep it for more than 5 seconds after the power turned on.
2) It generates red blinking series of the power indicator light.
3) Any operation would cancel the Self -Diagnosis mode.
4) The next table shows the PDP PWB in which failure most probably would be allocated according to the number of blinks.
Number of red blinks of power indication light ==> Presumed failing PWB of PDP panel
1==> Logic
2==> X-SUS
3==> Y-SUS, SDM SDM: Scan Driver Module
4==> X-SUS, Y-SUS, SDM, PSU PSU: Power Supply Unit
5==> ABUS, ADM, PSU ADM: Address Driver Module
6==> ADM temperature
7==> ADM temperature
8==> All of above-mentioned PWB’s

Hey I have the same issue, however I let it do that for a hot minute. At times I may need to turn the TV off and pull the round cord from the box and put it back in. If I let it sit for a long time it is hard to start. It's kinda like a cold two stroke motor, you gotta take power away then dump it back in and let it set. It's probably not healthy for it, however it is over 10 years old, or at least close to. Hope that helped
