My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...


You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

I have 50 in plasma phillips magnavox 50mf231d-37, will not come on red light flahses 4 times


this is some info that some one else had found

get a memory stick( flash drive) and up load their soft ware from their site. I plug the stick into the computor and uploaded the software. I then plugged the stick into my TV on the side. A screen came up and the software loaded on the TV successfully. The red light then turned to green. However, I now have to unplug and plug the TV several times for it to turn on. It works fine but once the TV is turns on, but when I turn it off and it cools for a while I have to repeat the same proceedure off plugging and unplugging

7 red blinking lights on tv


I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

No sound or picture just blinking green light


That sounds like a power supply Issue, Unless you have the full service INfo and proper equipment its best to call a repair tech for your model as an isolation transformer is needed to saefly diagnose the power supplies.
