Question about Akai PTH5498 54" Rear Projection HDTV-Ready Television
Before you go any further you need to press menu on your remote go to picture press select and then go to convergence press select again then a white cross should apear on the screen. Your objective is to converge or line the blue and green crosses up so that they appear as one cross. After you do this look at the directions at the bottom of your screen. Select the prompt that lets you continue. After you press continue several crosses should appear all over the screen do the same for these crosses as you did on the previous screen. This should solve your problem. If this doesnt fix it there is no high going voltage to your green and blue CRT's (cathode ray tubes). This could be caused by a number of things. I would take it to the nearest service tech being that you are dealing with high voltages comming from the tripler so high that if your hand or tool gets to close it could arc and ground through you even if the set is not connected to the power source
