Just recently the picture on my TV seems much larger than the screen itself. I no longer have my manual and can not figure out if there is a way to correct this. It is quite frustrating watching any tv because it cuts off any words it there are any. Any solutions?
CHECK SMALL TRANSISTOR LOC.# 7571 OR 7406 AND
COIL 5405 AND COIL 5402 CHECK CAPACITOR #
2404 AND2552 OR BUY A KIT FOR THIS TV IS COST A ROUND 8 DLL YOU PROBLEM YOU HAVE IN HORIZONTAL CIRCUITY IN YOKE CONECTION CHECK A RAUND

The T-con board controls the picture elements on the screen. Usually replacing this board will solve the problem. If you can touch the screen and the lines disappear and later reappear, that says the screen itself is defective. The only fix is to replace the entire screen.
On my remote control for the TV, I look for the # key and press it as many times as necessary to get the correct size picture that is needed to fill the entire screen. Sometimes for some shows, you cannot get the picture to fill the entire screen and then there is nothing you can do to get the picture any larger.
Hi, Question shows its Sony KDF-50WE655 dlp tv that has lamp inside and it seems its time to replace lamp. Did you replaced lamp in tv recently? If not, replace it. Lamp replacement procedure would be written in user manual and please buy Sony original lamp for better result. Thanks.
Several possibilities, if you use a set top box to get your signal like a cable box or satellite receiver they will have settings that effect picture size. It could be a high voltage problem inside the TV causing an effect called blooming, if that is it you can usually change brightness and or contrast and see the picture get smaller and larger. I don't recall that set having any customer settings that could give that symptom.
Me too! Apparently Diboss are no longer trading, so no help there. I am aware that these panels have a common power supply issue, the faulty chip is only available from China and the last one I fitted only lastest a couple of days. However the fault described above is not the same. I've checked the psu outputs; all are fine and nothing changes when the picture disappears, therefore I can assume that I'm not looking at a PSU fault. As Iain says above, it appears to be a signal link, however I have no picture on ANY input and without circuit diagrams I cannot find any component that's common to all the various inputs. This leads me to think that either the backlight, or the screen itself is faulty. I'll keep trying and if I get it sorted I will report back.
