This tv set plays for about 15 minutes and then goes dead and the green light blinks. Has anyone had this problem and found a solution for it? Thanks!

Hey guys! It has been awhile since I've been on here. I hope everyone is doing well. I just picked up this Sharp lc-65ub30u. It plays but the screen is flashing on and off. Other than that i seems to be a great tv. Any ideas what the problem might be? I haven't pulled the back off yet. I thought I would get some opinions first. Thanks in advance for any help you can offer.

It's been a while since I've checked in here or needed input on narrowing down what to replace on a TV repair, but I've got one on my bench now that has me wondering. The lack of part (board) availability means I may need to do some component-level diagnostics, and a second opinion is always good when it comes to that.
The issue - Sharp LC-80LE844U does not display. Power light comes on for a while, then you can hear a relay click off and the light blinks twice slow, then five times fast. Service manual points to 'Panel Power Supply Error' with this code, but isn't much more help... -
I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.
Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.
Then each time... -
Sharp TV flashing green light 2x per second at constant rate. Various reset methods do not have any effect on it. Search here and found flashing green 2x per second indicate bad power supply, which I am quite certain now.
I am seeking help with basic trouble shooting to find the short-circuit on the secondary side that I believe is the cause:
The main PD connector:
PD-1 (PNL12V) : 0.02V
PD-2 (PNL12V) : 0.02V (fluctuating)
PD-3 (SGRN) : 0V
PD-4 (SGRN) : 0V
PD-5 (UR13.2V) : 0.05V (fluctuating)
PD-6 (UR13.2V) : 0.05V (fluctuating)... -
