Question about Tatung P46ACTP 46 in. Plasma Television

1 Answer

Light goes green but no display.

Hello and thanks in advance! I have a Tatung P46 Plasma TV. The TV will come on with amber light when switch on rear is applied and 2 relays click on and maybe back off. After I hit the power button, the amber light flashes and then I get a constant green light (no relay sound). There is never anything on the screen. I checked the 4 fuses and they are fine.
I have searched to the end of the internet and cannot find anything on a Tatung P46. I found Vizio P46 but not the Tatung. I would like a service manual so I can test the power supply. From what I see it has a good AC input and the red and white output shows 4.2VDC.
Any help at all will be very much appreciated!

Definitely Power Supply Board. Check carefully for open 1/8 watt metal film resistors. They wont show signs of overheating but they can be open anyway. I've never been able to find a print either. Once you do find open resistors make sure you measure for shorted components in the associated circuit.

Tatung monitor Power light shows yellow light.


It sounds like your resolution or refresh rate is out of reach for your screen.


Restart your computer (even if it will be manually unplugging the power cable)

If you have no display while your computer starts up; you might have a hardware failure. Swapping your screen out, or plugging it into another computer (that works) will confirm if this is the issue.

If you can see the computer starting up you can press F8 (on your keyboard) continuously just before Windows can start.

Select "Safe mode" so that you will have the basics of screen settings.

Now you can go to control panel, display and click on the Settings Tab at the top. Change your settings to a rather default "1024x768" resolution and change your referesh rate to nothing more than 75hz under the advanced icon.

Hope this helps!?

Plasma wnt stay on


I have had this problem in some models of plasma sets before. In most cases the power supply and main drive boards had to be replaced. In a small number of cases the failure was the screen itself.

In all cases, the cost of the repair was expensive. For the screen failure, the set was scrapped.
