Select a random picture from the gallery - by clicking on it - ( to make sure it changes & your Flashplayer is ok )
Select the picture you want to display, if its not one in the gallery, click "browse" and find the photo you want - double click on it, make sure its in the display panel. Note sometimes the image will be blacked-out. This will either be a flashplayer problem or the file you selected the photo from has numbers or / ., etc - you can try renaming the file.

On the back of th panel are list Vs, Va voltages. Find the test point on the power brd. Labeled on one of the connectors. See if voltages match. If they are slightly off find coresponding trimmers and adj. if way off disconnect x and y sustain boards from power board. if stays low then replaced power board. if it is normal with x,y disconnected then one of sustain boards. if voltages all ok suspect panel. ry checking other inuts first to see if this is a vseo problem or not.

Hi: When you say small horizontal screen, ¿Do you mean picture does not fill the screen completely from top to button? ¿Do images display normally though they are smaller in size? ¿Is color and definition of signal OK? Please answer so I can have a better picture of the problem.
