Re: TV will not power on

I guess you already tried different outlets and plugging the TV straight to the wall outlet. DO NOT ATTEMPT TO WORK ON THIS YOURSELF!! Have a qualified tech come out and look at it. First, call around, found out where the reset button is. Get price quotes.

T.v.says lamp not working

If the display indicates then it is possible that the lamp has failed or that the Power to the lamp is cut off. You will need to check the status of the lamp and also the lamp connectors, the supply from the power.
Check to see if the cooling fan is clogged and so has reset the processor with a error. If so clean the filter to reset.

Same problem

It sounds like the classic "timer problem" that requires a "kit" (mostly capacitors) to repair it. To have someone do it (such as your service person) for you can be expensive and time consuming. Sets that are 5 or more years old usually have other problems too which, simply put, is a complete cleaning of all mirrors, fans, and filters.

Well call sears back and ask them if they fix it will they use the $100 for the repair? If they says yes then do it as sears will then warrentee the unti. Otherwise you need to take it in to save $100 trip charge. The reason why its shutting down is you got a bad power supply unit and this would need to be replaced.

If TV goes off and the led stays blinking, that is because the TV is going on protection.
Protection is a special diagnostic mode that starts when an internal fault has been detected.
If this happens erratically while you are watching TV, then parts that can commonly cause the problem are PSU board, main board or digital board, ballast board and converge board on DLP, inverter on LCD, low buffer and sustain boards on plasma.

No Power on my 61z886 tv

If the set is only 3 months old, it is under warranty. Place the old bulb back in to the unit and return it for warranty exchange or repair. Basically the set is going into shutdown because a problem was detected inside. This is done to prevent further damage. This will be covered under warranty.
