Hello, and sorry you're having problems. We are now connected on this website- which saves you money over having a Tech come to your home, and in many cases we can fix the problem you're having. In other cases, these things do require additional parts to fix. But I can help you with that as well.

This is a fault of the Mainboard in the set- which is not uncommon, and is something we've seen frequently on the site. To fix the TV, you can fit a Mainboard into the TV yourself (it does not require soldering or special tools). Or you can opt to have a shop perform this repair- but this is on average a $250 job, and perhaps not cost effective on a 10 year old 32" set (since the TV can be replaced for almost the same cost).

However if you're looking to perform a DIY repair- let me know and I can search for a source for the part and post a link if applicable. I will need the model number off of the back of the TV to search though.

There are no pushbutton fixes for this however, and the cycling Off and ON is a fault in the "EEPROM" of the Mainboard which does require replacement of the board.

Feel free to reply back if you need more help, or want to reply back with more details. It does not cost you anything more to reply back once you've rated. Please do rate me positively (at least 3 STARS) and I will continue with you until this is sorted. The positive rating ensures I am credited for my work.
