Good Morning

I have laid them flat, turned them back up, plugged them in without issue. I think this is just a myth but like all myths there must be some truth.

To be safe wait an hour... Then if its messed up RETURN IT... :)

Have a great weekend

Hi,

This is an internal fault as you must have observed. There could be many causes for the same. It could be a problem with power supply board. Other than this, it could be Y and Z sustain boards. However, it needs a proper inspection and testing of these components. If you have electronics repair experience, know how to use multimeter and soldering iron, could read schematics - i would be glad to provide you with a link to purchase service manual ( if available ) and could guide you to fix the problem.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

check for bad caps on the power board

Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

You will find the Y sustain board part number here.

if you PC has one of the following outputs then it will work ...
composite (rca jack) , S-Video , HDMI or component (three wire rca jack) ...

several video cards have at least composit video out as well as the normal VGA output . look for a single RCA.jack ....
if your video card does not support any of these formats then you would need a VGA converter box to one of those formats ... there is also a USB to s-video/composite converter cable ...

the resolution of your set is 1024 X 768 ... so thats what you would set the video card for ..
