Unit turns on briefly and projects the startup screen, but then turns off.
This unit is 3-4 years old and has always worked perfectly. Now it turns on long enough for the blue notevision screen to show and then powers off automatically.
I replaced the bulb with a new one and that did not make a difference.
Any help would be appreciated!

When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.
A model number would have helped me diagnose your unit but because you say that you have white dots on the screen, and the unit is only 3 years old, I will go with what I believe your problem is. I am assuming that you do not have a CRT projection unit. I believe you have an lcd projection tv which is starting to have TFT panel failures. As they age they lose more and more pixels which show up as white dots. The only cure for this is a new optical engine. Cost could be on the order of $350 US. The replacement is not that difficult and can be done using my tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which will walk you through the process as well as link you to the best place to get the parts you need.
Thanks for using FixYa and for the excellent rating. Great ratings keep experts helping everyone solve their problems. Thank you.
you got a YLOD yellow light of death when you get a yellow light briefly and then the red lights start blinking, you need to reflux the solder on the processors and apply heat to them, here is a link on how to do the repair, if you are not good at doing these kind of work, I would suggest taking it to a pro. http://www.youtube.com/watch?v=XIm0Qk0CVTE&feature=related
YOUR PSU (POWER SUPPLY UNIT) MAYBE THE CULPRIT. If the power to your cable which fits the computer is ok, then the supply unit is usually at fault. You can buy these pretty cheaply on ebay and they are very easy to fit, or if you are not into that find a mate who can! beleive me... its pretty easy.
I've tried the Home and A button several places... and it seems to work for others but not me :( I was about to give up then I found another way to reset the screen - Hope it works for you!
1. Unit must be OFF and NO cartridge
2. Hold down the HINT (?) button while turning the unit on
3. When Leapster menu screen appears, press the A button
4. Touch each of the cross hairs that appear with the stylus
5. Restart unit
Replace IC 7301 located on the Red crt board. part # 875968001
also check the focus block part #122392535. If this does not cure your problem the Red CRT is bad. if the unit is over 3 years old replace all CRTs.
Always have a qualified tech work on your set.
