Power supply problem ,tv don't swicth on at all no power, model no;42px4mvh-TA

Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Sound working no picture

It definitely has a problem, possibly the Y sustain board and y drivers Up/Lwr. Best suggestion is to take it in for service or have someone come out how has experience with Plasma repair.
