Question about Televison & Video
First thing to do is a hard reset. Merely unplugging the RPTV power cord for 4 hours, then power up again.The purposed of unplugging is to dissipitate the stored current in the memory IC so it will gone.
If the reset does not help, try disconnecting anything on input 2. For example, if you have a dvd player connected to that input, the tv may be sensing its presence and switch over to it. (Especially, if the device is left ON.) Again resetting if that does not help,then there is something wrong. The power supply is in protect mode. There is most likely a short on one of the boards, or the high voltage generator, or a scan amplifier, or the power supply itself has a failure. Without troubleshooting the set it is impossible to know.The blink codes are provided for the electronic technician as a starting point to start checking for problems. This blink code suggest that there is a problem with a couple of IC's on the D board. Please be careful if you remove the back of the TV. The manifacture recommends that there on user serviceable parts inside. This is due to high voltage being present even with the TV unplugged. The problem is very likely a power supply and a convergence IC issue a problem this TV is known for. These sets are assembled using the wave soldering process they are known for having cold solder connections. This model of TV has over 2,000 parts which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad. This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equiepment specifically designed for TV service and the skills to use the test equipment. In this case, the set would need to be seen by a tech who can get inside and test the circuitry that controls the function switching. Lugging a big set like this into a shop is not easy, but is will save you lots of money compared to having them come to your home.
Let me know if you need more....

Whether you use your DVD drive to install software, make backups of your personal files or watch movies, having that drive onboard makes your computer more useful and more versatile.
While DVD drives function normally most of the time, sometimes a DVD will become stuck in the drive, and the tray will refuse to open.
Knowing what steps to take to resolve the situation allows you to start enjoying the advantages of the DVD drive again.
Log on to your computer and click the "Start" button. Choose "Shut down" from the menu and then choose "Restart." Wait for the computer to restart, then press the eject button repeatedly.
Remove the DVD if the drive pops out.
Since there is no hole skip this and go to cleaning the lens.
Shine a flashlight on the DVD tray and locate the small hole near the eject button.
This is the bypass hole and it allows you to eject a DVD when it becomes stuck.
Insert an unbent paper clip into the hole and push it in until you hear the DVD begin to spin. Push the paper clip in until the drive pops out.
Remove the DVD and insert another one.
Use the bypass hole again if the new DVD becomes stuck.
If the new DVD sticks as well, you need to clean the laser lens on the DVD drive.
Insert a laser lens cleaning DVD and close the tray.
Run the laser lens cleaning program at least three or four times to make sure the lens receives a thorough cleaning.
Restart your computer and insert a DVD to test the unit.
