HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.

FUSE CHECK LIST--

3A 12v- fuse----(242208600623)
SM 3A 125v-fuse----(242208600657)
500 MA-fuse-----(242208611092)

My Samsung TV won't turn on


Please describe the problem more accurately. Flashing red usually means 'stand-by' state, flashing blue/green - starting up. When (during that) do you have a sound? Are there any 'high voltage' sounds like soft screeching from the screen? Is it LCD or LED?

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Telly on but no sound orpicture


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL2100 you can find it here http://www.discount-merchant.com/Sony-XL-2100U-TV-Lamp-p/sony_xl-2100u_replacement_lamp.htm?Click=48173 .Have a blessed one!
