my tv is an sony vega kdfe55a20 this has been happening for about 5 weeks now. Out of 16 hours of running the TV, about 1 hour after turning it on the morning it goes out for about 30 seconds, when it comes back on, the picture comes on dimly and then brighter to full brightest of a normal picture. It does this 2 or 3 times at most and then 15 hours later it does this again. This problem is progressing in intervals throughout the day and duration length where now it is happening 15 times a day and for about 1 minute each time.
NEW QUESTION:
I need to find out the sony troubleshooting page that describes all the LED flashings for troubleshooting, being that my picture is getting darker all the time. So when my bulb does go out, the flashes will tell me something, hopefully.
I am not getting an error code. I want to make sure it is the tube before I purchase.
How can I run diagnostics on this to be sure it is the tube and not a fan or other part that needs to be replaced? Also, if it is the bulb, can I purchase just the bulb or do I need to purchase the whole assembly? I need to find out the sony troubleshooting page that describes all the LED flashings for troubleshooting, being that my picture is getting darker all the time. So when my bulb does go out, the flashes will tell me something, hopefully.

Hi,
Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.
Replace lamp in TV to solve this issue. Lamp replacement procedure is written in user manual and its an easy work.
Please buy Sony original lamp for your Tv safety.
Thanks.
Hi,if your tv is between 2-4 yrs and you don't hear any strange noises it might be time to replace the lamp.This will be the lamp you need: XL5200 The Original is made by Philips and it's the best lamp in the market.You can find it on discount-mechant .Good luck and God bless you!
Your problem is your thermal fuse.It is located around the bottom of the compartment that houses the lamp. You will have to remove the lamp and take the bottom back panel off. Then you will have to remove the fan. I ordered the thermal fuse so I would know what I was looking for when I started to replace it. If you take your time and are patient enough you can fix it yourself. I fixed mine and it's working great.GOOD LUCK!!!
it would probably be easier to have someone come out and take a look at it before you go buying parts you may not need to be spending money on. it may be a simple fix for a repairman and not so simple for you...
I have the exact same problem with my tv. Unfortunately, I'm not sure what is wrong or how to fix it either. I notice your post is from July. Have you found a solution since then?
