Question about Sony KP-53HS30 53" Rear Projection HDTV-Ready Television
This set could have a few differant problems to cause this to happen. Lets explore them. Pull off the front speaker grill off the front of this TV set. Take the the screws that hold on the wooden panel. Now behind this wooded panel you will see a block with six small controls on it. There will be three focus controls, and there will be three screen controls. before you turn any controls though, mark where they are located so you can return them to the place where they were set before you turned them. Now we are only interested in the screen controls for now. With the set on, and do not touch anything else, slowly turn up the middle screen control clockwise and see if you get any light on the screen. If you go all the way and no light, you have a problem in the vertical drive circuit, or the screen block is bad, if there is light but no video, you have a video problem in the video drive or RGB drive circuit, and if you do get a picture, turn up the other two screen controls and balance out the picture. If you do not get anything, return the controls to the priginal postions. This set will need to be dug into deeper to find out where the fault is. Tis video blanking is a safety circuit in this set to prevent damage to the picture tubes. If you understand how these circuits work, I do have the chassis(RA-6) Manual for this TV set. if you think this will help you trouble shoot this TV set i will send you a copy via e-mail and save you 25 or so bucks. Leave an e-mail address if you wish to have a copy. Good Luck
