Sony 53 inch projection screen with hourglass picture

I have a Sony KP53S25 projection screen that works fine when first turned on but after a few minutes the left and right sides bow in like an hourglass. If I turn it off and back on it is fine for awhile but always returns to the hourglass picture. I've been told that it is a convergence issue. Is that adjustable or do I have to replace a part(s)?

For your information, the problem as you describe it is not a convergence problem. It is what is called a "pincushoin" problem. The D board contains the circuit to address this.

If you are familiar with TV repair, have electronics basic knowledge, good soldering skills and tools then check dry (cold) soldering joints at D board of this TV. Resold all lose connections there and check picture.
Still no joy then you need to replace D board.

Tv screen will not stop blinking


It sounds definitely like a faulty power connection via the video cable from the inside. If it blinks a while then turns black then shows the picture, it would have to be that it's not screwed on properly, thus taking more time for it to get a full charge and then properly function. If you still have the warranty, any electric repair/retailer shop can fix it for you.

two three-pin voltage regulators near the left side (looking in from the back) bend over from the heat and short to a ground rail. Check and straighten them with the power off and the unit unplugged

52 inch sony rear projection t.v.


Whining sound most likely is a bad flyback transformer. You are probally looking at a 350-450 bill depending on the repair shop. If your picture was "great" go for it. If the tv has a lot of wear let it go. Nothing the repair shop does to fix your problem will make your picture better than it was before it went out. Somthing to contemplate.

Big screen troubles....


It is either going to be a shorted blue CRT (picture tube) or a driver board for it. I suspect the CRT itself.

Sony KP 53S65 53" rear projection TV contrast issue


While the root of the problem is likely the picture tubes aging, I'm sure it would benefit from a cleaning and adjusting. After the dust is cleaned from the lenses, the screen controls could likely be lowered to get the blacks you desire. An experienced tech would be able to do this for you.

your problem is a defect with the b+ going to the crt driver transistors such as a capacitor off the High voltage tranformer or could be a coil or resistor that changed value in the filiment curcuit. This is another hard one to say without more info. if yuo dont do any troubleshooting or dont have the know how then Im thinking its best that you call a pro.. Good Luck
