Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television
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.
