Display off after some time


As you have checked all of the removable components. That only leaves one bit left. The motherboard. Check the capacitors around the CPU socket and the Power connector. There is a common problem with Socket 775 CPU it is that the contacts on the CPU socket can be badly connected even when the CPU is fitted and locked in.

I have Samsung HL-S5087W for about 5 years and it is turning off by itself-any suggestions?


i hope your TV is getting ''off '' by itself when you are trying to turn ''on'' - not when you are watching TV...........then following is the situation ..........IF LED IS BLINKING then---- usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ..but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ..........IF LED IS ALSO OFF then on main board in power section area some component is deffective ... MAIN BOARD SHOULD BE CHECKED COMPLETELY........ so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) ........iam from bangalore.....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact samsung service centre.........
