The picture is unclear with a large red spot in the center

OUCH! LARGE DARK SPOT IN CENTER IS NOT GOOD FOR PROJECTION TV. YOU BURNT THE TUBES. THE LOSS OF COLOR IS THE ROOT CAUSE SOUNDS LIKE A DEFLECTION CIRCUIT PROBLEM. THE TIMING FEEDBACK IS USED TO SYNC THE COLOR CIRCUIT. IF THE TUBES LIGHT WITHOUT DEFLECTION THEY BURN THE CENTER PHOSPHOR COATING INSIDE.

Your light engine is going bad.

i think there may be some dead pixels.try to check it

can you attach a picture?

when you replace the convergence amp board. u usally have to go into setup. or service mode and manualy converge the set. these settings are what perfect focus basis it reconvegence on. sort of the factory settings. these faint lines may also be a red crt overdriving too

This 30" flat screen TV set may have a problem in the high voltage circuit of the TV set. You may be able to adjust this by taking off the back of the TV set. Look for the block where the large red wire runs up to the top of the picture tube. On this block will be two controls. one will say screen and one will say focus. Try and slowly turn the control that says screen or S on it clockwise and see if you can make the picture brighter. Turn up the control till you just start to see faint lines in the picture, then back the control down till the lines go away. If the picture does not come up when you turn this up, and all you get is a blank screen, you will need to have this set repaired by a qualified repair person. Good Luck

youll need to replace the stk ics inside the tv. they are easilly found by looking for two larg heat sinks. im pretty sure sony runs stk392-510. you will have to look at the ics to verify.

Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.

is the pic bright red or dim with no video and small faint red lines??? if the picture is there then it sounds like the red screen on the High voltage block may be turned up a bit to high. Was somebody tring to focus the pic latly>> need more info please>

The spot meter area is small because I have photographed 2 people side by side many times, focused on ones chest then found that the "spot" had slipped into the little space between them, the bad focus not really showing up when I checked the LCD. (My eyes are old and so are my glasses.) Got home and found useless pictures. Sometimes I was outdoors in the sun and couldnt check the LCD. Some of the threads say the focus spot is "off center" with no acccurate way of finding it when using the viewfinder. I take some beautiful, wonderful pictures but these errors really tear me up. I've got to get the LCD box viewer with the 2x lens viewer I guess. All those years as a 35mm Canon F1 user I would long for a spot meter almost daily. Now I see that a matrix meter AND a spot is the real choice. I hope eventually to learn to outwit my 3000Z because it does give me such excellent pictures. Sometimes there is noise on a face, sometimes it is the focus and at functions it is so embarassing to ask a principal subject to wait because the *** or ***H procedures take so long. A wedding, other than the reception, would be near impossible in *** or higher. Good Luck, Dav.
