Question about Proview PL926WBi 19" LCD Monitor
Serial #: F0A255049271U Purchased at Costco The TV has a loopy gasket hanging down from the top. This detracts from the picture and is annoying.
SOURCE: Proview 3200
My Proview LCD TV Model 3200 - 32Inch is blocking certain screens and the message that shows up - V-Chip Block TV-y7fv - can you tell me how to fix this issue?

hi first of all u should check ur transistor connections.Check your Horizontal and vertical output transistors.You should also check the horizontal and vertical yoke connections as well as your low voltage regulators.... if any of these got damaged u should purchase a new one.. but try to purchase with the help of a tv service assistant...

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there are some troubleshoot you will have to do to find out the causes of the problem you are having.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:
Please see my basic troubleshooting guide here:
Please post back what you find.
You may have the same cause of the problem (blown fuse on T-CON board):
