SAMSUNG PLASMA TV PS43D490 NO DISPLAY LED INDICATOR BLINKING AND RELAY CLICKING REPEATLY
If you find plasma tv with no display sympton and relay on PSU Clicking repeatly..maybe there is short circuit.So i try to disconet suplly wire from main PSU to Y-Sus Board..and try to power on again.. TV Set can power on..no display but i can hear sound from speaker..This indicates that the system has worked although plasma panel supply.next step i conect supply wire from Main psu to Y-SUS board..and disconect supply wire from Y-sus Board to X-Sus / Z-sus bord to lacalize wheater short circuit come from Y-Sus or X-Sus / Z-sus board.Turn On tv set again and first sympton... no display-led blinking with relay clicking on Main PSU... I try disconect supply wire VA from Y-sus board to X-board..but no result .I suspect short circuit come from Y-Sus board... wehen i cek more detail i found short occour from output VA Supply.. 1 HV milar capasitor burnt and 1 IGBT transistor short.. so i replace it and short circuit from VA output supply clear
