20 Most Recent Philips Magnavox 27MS343S 27" TV - Page 2 Questions & Answers

The issue here is that the zeners in question are merely like a safety fuse and replacing them before identifying and fixing the cause of the problem will only cause your replacement zeners to blow aswell.... personally if it is a true plasma it likely chews through alot of power anyway so I would take the opertunity to replace the TV with a newer much less power hungry led TV and in doing so save the hip pocket and the environment.

If this model number is what I am seeing then it has an aerial socket so needs an aerial and then setup to tune it in, perhaps you do not have or allowed an aerial then its broadband and one of the companies that have TV feeds. If its not what I think and an analogue thing then you need a "box" to do this feeding a video audio signal via another cable. Without more info hard to give any other advice.........

hi.... i did child lock my tv magnavox and can't turn on ,,,because my remote control is broke now.. so tell me please how could turn on my tv Please Tanks...

Strange, I have the opposite problem, I have the cord and camera, but no monitor. I found the following fix below to make this camera hook up to any tv or monitor, but it's greek to me. It may help you though! Or, if you can translate these instructions for me to hook up mine, I'l happily GIVE you my cord!

"The DC power was sent up the coax and the video is AC coupled and sent back down. If you open the
camera and trace the wire from the center pin of the UHF connector, it will lead to an inductor
and a large value capacitor. The video is coupled through the capacitor, which blocked the DC
power from the video output amp. The inductor (coil) blocks the video from getting back into the
power section.
Cut the inductor loose from the center wire of the connector. Put well filtered +12 VDC at 500
mA (1/2 amp) or greater into the inductor at this point while running a video cable from the jack
to a video monitor or to the video input of your home VCR. Then you can see the video on your TV.
Power return is to the ground of the connector or any other convenient grounding node.

Most likely the power supply and/or related circuitry has failed.
