Google Dell W2600 blink codes. You're tv is doing a self diagnostic and letting you know what's wrong with by flashing the yellow light. Count how many time and if there is a sequence to it, then look it up.

Television does not turn on


please check the ac plug at the wall and also behind the tv. most newer tv's have a cord like a computer that plugs in the back and they sometimes come loose. are the rest of your electronic components working ? if the ac cord is plugged in, your power supply inside the tv has gone bad. you cannot blame your 2 year old if this power supply has gone bad, this was "NOT" caused by playing with the remote control.

If your LCD is less then a year old, I would suggest to contact the manufacturers to have it fix under warranty.
The failure on your LCD could be a defective back light inverter or a power supply not providing enough power to the back light inverter board.
Let me know if you require further assistance.

Hisense 42inch lcd tv


It sounds like it's the inverter panel which lites the lcd back light.
If it's under warranty, try to replace it, or take it in for svc.
