    Power on 65" big screen went out, and wont turn back on. No outages..Doesnt blink at all, but light comes on for split second then turns off right away. I unplugged tv, and plugged back in. No fix.. i opened back panel, and checked a close by clear fuse. Seems to be fine. No black marks, or signs of it being blowned. pulled power source plug from circuit board, and plugged back in. Then plugged tv back in and turned on, but still no fix..I can hear a clicking nose going on and off, when i try to power on the tv. It comes from about the middle of the board close to two brownish red cylinders.. Can you help me out here? Thanks,,

    I have the same problem. After a very bried power outage my tv now has a blinking green light and it will not turn on. How much should a reasonable repair shop charge to fix this tv?

    Problem originally started when the remote quite functionong. Then the front panel buttons except the power button quit functioning along with I am only able to use the antenna input. Is there a simple fix, or is this great TV ready for the trash heap?

If you are lucky, it's only a blown fuse, but with a blinking light on the front, this is doubtful. I would pull the back cover anyway and check the fuse. If fuse is ok, then normally if you have no sound and no picture, you have a blown "horizontal output transistor". Look for the big wire (usually red) coming from the picture tube to the circuit board. The red wire goes to a large object on the circuit board called the "flyback" transformer". Usually very near this transformer you will find the h.o.t. (horizontal output transistor). It will normally be mounted on a silver piece of metal (a heat sink), about 2 or 3 inches square or possibly rectangular. The transistor has three pins coming out of it and is probably the largest transistor you will see that has only 3 pins. The upper portion of the transistor will be clamped (or screwed) into the metal heat sink. You have to desolder the h.o.t. and replace it with a new one. The h.o.t. usually costs only about $10.00. If the fuse and h.o.t. are good, then the "flyback" is probably bad and they run from $25 to $100. If the TV is worth only about $200, then replacing the flyback is not recommended, because there is no guarantee that this will solve the problem. Keever.

Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).Buttons don't work
• If you're using the remote control, press the TV button first to make sure the remote is in TV mode.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).• Unplug the TV for two minutes and then plug it back in. Turn the TV on and try again.TV turns off unexpectedly • Sleep timer might have been activated. Go to page 24 for instructions.• KidPass might have been activated. Go to page 21 for instructions.• Wake-Up timer turned on the TV and no remote or front panel buttons were pressed for two hours.• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then
turn on again. If this happens frequently, the voltage in your house may be abnormally high or low.

Check the remote carefully for a stuck button. You may have pressed a button and it went a bit crooked getting stuck.
Also, remove the batteries of the remote and try operating the TV manually. If the remote is the cause, the TV will work correctly once you remove the batteries.
Another way to check is by using a digital camera, like the one in a cell phone. Turn on the camera and point it at the remote. If you see a white light coming from the transmitter, the remote is sending a signal. Look for a stuck button.

Blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.


Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

TV won't turn on


The set is in protective shutdown because a problem was detected. The 5 blink code indicates that the problem circuit. In this case it is the blanking circuit. Were there any indications of problems prior to the storm? If not, I'll need to lok up this one for the specifics. Do you intend to repair this yourself?

Let me know and I'll provide the details.
Thanks,
Dan
