Hi plasma lg tv 42px4mvh-ta when i switch on it does's not switch on, i contacted technician the Guy told me that the main power supply board has a problem of suppling power how will you assist me


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. 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.

Lg 50pq20d plasma tv not switching on but voice comes out


Aside from checking the fuses it likely will require a technician or a shop to examine the set to see what is wrong and what needs to be replaced.

Sounds like a power supply issue but that would need to be checked.
