My tv shuts off and the timer, lamp and standyby/temp lights in the front on the power button flash on and off. It takes a couple of minutes for me to be able to turn it back on. this is a random problem most of the time i have no problems with it

This is a common issue with these. When the bulb fails it can put added stress on the power supply and cause parts in the supply to fail. They are not meant to be serviced by the end user. I would check to see if you can locate a parts source for the power supply.

Possible lamp or color wheel---remove the lamp and look to see it is not shattered inside.

The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Most likely the temp sensor above the lamp housing. Jump the blue and white wire plugged into it and bypassing sensor and the tv should work.

replace the lamp only takes few min make sure you get right one for model of tv the LAMP MODEL number will be on OLD LAMP the tv will work and sound will come back hope this helps

Most likely needs a new lamp. Easily done yourself.

You definitely need the lamp. If you can provide the make and model # i can probably tell you which lamp you need.
