This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.
Ur tv have convergence problems,it dead.U must know how to solders,have soldering tools,and solders to fix convergence problems.U must replaced 2 STK Convergence ICS,and some or all it resistors.Tries wesites like Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.
means you prolly have something wrong in the tv with the actual board or chip in your tv. im not fimiliar with your model but i have a panasonic viera and it wouldnt tuen on shortly after and they said i had to send it in for repair
First check for a faulty capacitor on the power supply board as it sounds like that could be the first place to start. Before you touch any capacitors PLEASE find articles on the internet concerning discharging them as one stray discharge incorrectly could not only destry your tv but hurt you or even KILL!!! Ignore any articles that tell you to use a screwdriver. Good luck.
This is a common problem with older Philip Magnavox projection sets. Over time one of the IC chips on the main power board begins to fail. You can find replacment chips and repair instructions on www.magnavoxhelp.com.
