Question about ViewSonic VPW505 50 in. HD-Ready Plasma Television
Just bought this TV used. the screen flashes and flickes and it is mainly visible on light portions of the picture. Its a steady flicker around 2 times per second. Is this TV worn out? Is this a common problem? Is there a simple fix?
Got it. I was the 'guest' who posted that I had the same problem. Not the CTRL board as I earlier thought. It boils down to the Y-SUS board (right hand side as you face the back of the display) In the upper-upper left hand quadrant you'll find a small capacitor labelled "C70".
This is the naughty one.
You can verify this by removing the back of the display, powering up and then with a small extended flame lighter, GENTLY warming C70. All it takes is about 2 to 3 seconds and the display will steady up just like always.
C70 is a surface mount capacitor, most likely 33uf at 25 volts. Haven't confirmed this yet. Will post again when I've affected the repair on my VPW505.................
BTW: This is not something you want to attempt unless you have experience with electronics. No.....really!
