the problem is in the power supply(they know about it good luck fighting them)but there is good news.you can remove the power supply and replace electrolytic caps,EC18,EC19,EC20 all of them are 1000mf at16 volt use 1000mf at25 volt.you can also go to shopjimmy.com enter model number you will see power supply part number MLT169B
it will be cheaper for you to replace the caps,the board cost about $80.00 from them
