Try a reset to this TV and check. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

SOURCE: TV freezes when switching to a digital channel

The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

SOURCE: screen black. polaroid tv 32". have sound TV/DVD Combo TDA-03211C

sounds like inverter board. What it sounds like is happing is your LCD is working ut the backligkt board that allows you to see is kicking off. (as you still have sound) Which could be the (most likely) inverter board, or the power supply board. You can take apart and check for voltage at your power supply. The power supply has a pigtail with large white wires and a connector. Power up with the center back cover off and check your voltage at the white connector on the power supply before and after the screen gos out. If there is no large voltage loss it is your inverter board.

You can used boards on e-bay or

SOURCE: Polaroid 19" TV TLA-01911C has no picture. Powers up, see logo

To add to this solution above - I had the capacitor replacement and there was still an issue. Turns out the solder connection to the lamps themselves was very very poor causing an electrical arc (the scratching noises people are hearing) - then the inverter shuts the lamps down as it should. Fix lights!

Why is my polaroid 22 inch TV DVD combi not working?


Hello, it sounds like the main board has gone bad (the tuner is mounted on the main board). The cost of the board replacement may be close to the cost of a new set. You may want to explore that option....tks....Terry

Black box comes up on tv screen


The black box is a text box for closed captioning. Some stations send the signal which turns on the box while not actually broadcasting any text. Go into your setup menu and turn off closed captioning, or at least change it to a different mode. The easiest option is to restore factory presets.
