Power out unit turns off temporarily (between 1 second and 5 seconds) or off for good. If I was to have a hunch, it appears to be something like a fan not working and the unit shutting down when over heating, but this is just a laymans guess. the word --powerout-- flashes on the unit and off she goes... anyone??

To display memorized error (Protective operation)
status:
1. Turn power on.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit. The power LED lights up. If no abnormality is
stored in the memory, three beeps sound will be
heard.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard. 7. The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5
seconds or operating the unit for 30 seconds. 8. The same diagnosis can be repeated by turning
power on again.
• To clear memorized error (Protective operation) status after repair:1. Turn power on.
2. Press the AUTO button for 5 seconds (A beep
receiving sound) on the main unit to operate the unit
at Forced Cooling Operation mode.
3. Press the CHECK button on the remote controller for
about 1 second with a pointed object to transmit
signal to main unit. A beep sound is heard from main
unit and the data is cleared.
• Temporary Operation (Depending on breakdown status)
1. Press the AUTO button (A beep receiving sound) on
the main unit to operate the unit. (Remote control will
become possible.)
2. The unit can temporarily be used until repaired

I would contact the manufacturer and ask for the repair manual, it does not appear to be available online. Here is a link for the contact form. Hope this helps.

Hi, 1. Switch the source OFF. 2. Enter the Time setting mode.Hold ^ button for 2 seconds 3. Select "Hour" or "Minute" with the 2/3 buttons. 4. Set as desired time with the 5/° buttons. As soon as you switch to "Minute", the seconds start counting from 00. 5. Cancel the Time setting mode. Note: ? Holding down the AUDIO button for 2 seconds also cancels the Time setting mode. ? To turn the time display ON. The time display disappears temporarily when you perform another operation, but the time indication returns to the display after 25 seconds. Note: ? When the sources are OFF, the Time appears on the display. Pressing the CLOCK button switches the Time display ON/OFF.

Turn On the unit with the remote controller
Wait until "no disc" appears in the unit's display
Press Pause, 3, 1, 4, 1, 5, 9
The word "CODE" should appear in the display
Within five seconds, press the key that corresponds to the zone you want i.e. 0 for region free, 1
for region 1, 2 for region 2 and so on
Again, within 5 seconds, press Pause and Power

Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.
