Hi.

If there is sound but no picture, screen is completely dark and the picture is occasionally flashing, then the fault is likely a faulty inverter. In some case a faulty controller board or a defective PSU can cause the same problem.

I summarized the problem here:My LCD TV has sound but no picture.

I posted general procedure to test inverter, PSU and controller board on LCD here : How to test an LCD TV or monitor PSU and inverter.

If screen is not dark, but has blacklight or noise things are different. In that case check connection cables first. Parts that may be defective are main controller board, terminal circuit and tuner board.

Protron parts are available using the link below. Ensure that parts are compatible with your model before purchasing.

Have protron pltv-32cm. model lt32c1m1. how do i shut off the v-chip block? i don't have the password.


Hello, there is a default password, if you source is in component 2 it can't be used here are some links to the pdf file pltv types.
V-Chip Lock When turned on, blocks access to mature television and movie content, based on the MPAA and TV PG ratings selected below, unless the viewer enters a password (set below). Set Password Sets the V-Chip password. To change the password, enter the current password followed by the new password. The factory-default password is '1234'.

Sorry, I don't recall an email from you FM. I usually answer within a day. The power supply will need to be removed from the TV and shipped to me. dave@thola.com  714-809-3461

DTV Converter Box


If there is no digital tuner built into the tv or unless you subscribe to Cable TV or Satellite service you will still need a converter to view tv with rabbit ears (air broadcast).

Good luck!
