Does it do this with other input devices? Sounds like a electrical surge.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

The second error is caused by the line stage not working.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hi,
Red light flashing on tv indicates that tv got some problem and shifted to protection mode to avoid further damage.
If Lamp light is flashing on tv then check lamp that would be dead or broke, replace lamp to solve tv problem.
If standby red light is flashing on tv then let me know how many times it is flashing after 3 seconds long pause to provide you helpful info.
Thanks.
