VIEWSONIC VPW505 Screen flickering

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?

Re: VIEWSONIC VPW505 Screen flickering

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!

Flicking screen on Samsung UN60FH6003F, replaced main & power board and LSVD cable.

Check out the inverter board. It supplies the backlighting on screen so you see picture. If it is messed up it could be responsible for the flashing. Assuming you see a normal picture in between flashes!
