Bulb still not working

Yes, lamp installation procedure is written in user manual of TV and click Sony Support to download user manual copy if required. Lamp replacement is simple process, take out old lamp and slid in new lamp.
Please buy Sony original lamp for TV safety.

The ballast for the lamp too should be replaced along with the lamp. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.

If you Google the model number of this set with the word lamp after it---you will find many places that will sell it---from about 109 dollars and up---make sure you get a lamp with the cartridge---the cheaper ones usually are just a bulb and you have to dismantle the cartridge and install the bulb your self into it.

Usually better to buy a complete lamp with cartridge that comes with a warranty.

If you have any questions or need help let me know-I am here to help people.

You can get the bulb in the cartride complete and just plug the new cartridge in or you can get a Philips replacement lamp from MCM Electronics for $99.00 and take the cartridge apart and replace the bulb. Until you put the door back on the set will not turn on.

there is a panel either on the side or back of tv. unscrew that then you have a cartridge that needs tobe unscrewed. thn remove bulb and click in new one

You lamp bubl has burned out. You need to replace the bulb. you can order a new bulb on line by searching the web using your model number bulbs are about $110 if you reuse the cartridge and replace the bulb only. replacing the whole cartridge and bulb is around $ 200

u sure it pluged in all way unplug tv take bulb out look at bulb not broken in side is it re set it in then reset lamp life on tv

I had the same issue when replacing my lamp for the first time. I replace just the bulb with the Phillips replacement bulb. After installing the power down issue started and it would take up to 7 attempts before the TV would stay on with a picture.

Since I never had this problem until i replaced the bulb i decided to send the new bulb back and replace it with a difference one. In my opinion replacement parts are never made to the same standard as original OEM parts. This TV is definitely very temperamental in regard to the bulbs.

When the second replacement bulb arrived I decided to not only replace the bulb I also cleaned the connector plug in the cartridge with a QTip and alcohol. I did the same for the plug receptor in the TV.

When I replaced the bulb i insured the the top of bulb lettering was facing the handle of the cartridge so when you put the cartridge back in the TV the top of the bulb would be facing you.

I also cleaned the entire inside of the TV where the cartridge is inserted including the screws.

Once I did all this the TV turned on the first time and has been working fine for three days now.

I do believe the replacement bulb position is very important as to how it heats up and determines when it needs to cool.

I hope this helps others with the same success i had because I really do not want to replace this TV and start replacing all the parts others have done with little to no success for this issue.

remove front panel under screen, rove screws from lamp access panel cover. then remove the screws from the lamp assembly housing pull lamp housing straight out. install new lamp in the housing and slide the cartridge back into set replace screws and access panel cover.
