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.

How do i Fix the complaint of no picture and only plain raster. CD playing is O.K. Philips CRT TV, Model No.21DI4210/94R


So many possible reasons from part failure to faulty connections inside.
I would imagine it has OSDisplays so are they there and working OK.
My only thought other than a service engineer would be to turn it fully off overnight then try again but I would think its an age related problem (heat causes bad connections or part failure)

sorry thats all I can think of.....
