We replaced the lamp in out tv and now the lamp light is flashing and the tv will not power on

A continuous flashing red light with the word LAMP on it would definitely mean you're going to need to spend a few bucks on a new lamp....or for a few more, upgrade to a TV from this century that doesn't require lamp changes :)

you need to replace the lamp This unit has 2 different LAMPS used, one is SQUARE and the other is ROUND.

Replace lamp in tv as existing lamp is dead/ broken so tv shows lamp light flashing.
Buy Sony original replacement lamp for good picture in tv.

Since you have replaced the lamp and wheel, next would be the ballast and power supply board. These provide power to the lamp and Samsung recommends replacing both at the same time. If power supply board is bad, it can destroy the ballast so replace both. This usually takes care of the problem.

Hi,
Red light blinking 3 times shows problem with lamp cover.
Lamp cover is not fixed securely in your tv after lamp replacement. Lamp cover is first thing that was removed to replace lamp, check lamp cover and make sure its back in place properly.
Thanks.

The lamp light does not have to flash on this set for it to be the lamp, and most likely it is just that, the lamp. These sets when the lamps get weak they will do exactly what yours is doing.

Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

My Sony lost its picture and had a flashing light. Unplugging for 36 hours solved the problem.

you have a bad lamp or balast
