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! Dave

The fans do run. Not sure about a resettable fuse?

That's just it, with the correct knowledge I can repair this myself.

Any ex-techs out there want to give me any advice? I already have the thing in 20 pieces looking for an issue. The only thing I have found so far is a chipped fan blade and that looks pretty minor. I want to test all the fans to make sure they are all running. Anyone know the locations of any other common failure points?

Thanks!

Internal power supply.

Thanks for the links!

I did try that and it didn't do anything for me. I wasn't sure where the timer was since the unit wouldn't stay on long enough to tell me. I swapped the bulbs and reset the timer just in case.

I think the solution here will be to buy a new projector, this one is fairly old and the cost of repair is pretty high relative to a new unit.

Thanks for all the time and effort spent helping!
Dave

Do you have fans running ? Would you consider an overheat situation or a resettable fuselink blowing-cooling resetting etc. Sharp Tech Support would know all about this,

Well I guess that is what you will have to do
My biggest fear is by the time you have paid to ship it and seen the repair quote- you may well be into buying the next one.
Thats the way of things these days.
US/UK repair hour rates make it cheaper to junk and replace- what a waste

The fas running no issue with one aspect of the power supply.
How does this one get its power?
Is the power supply builtin or is it a separate unit that plugs to the wall socket?
Power us split to various levels - for example

12 V for lamp 5v for electronics Fans can be either.
Now a Google/Yahoo may reveal a source for thing like this- I am not aware of a site myself -but for example[again] printer problems are catered for by www.fixyourownprinter.com
There is also a comprehensive site-for all thing computery -www.overclockers.co.uk
Take a search -keep in touch

I HAVE A 20 INCH TV NOT A FLAT PANEL. ONLY ABOUT 3 YEARS OLD. IT TURNS ON AND THE SCREEN TURNS GREEN, THEN SHUTS OFF. ITS ONE OF 2 TVS I PUT ABOVE MY BAR. ANY IDEAS?

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.

Samsung 42 inch projection tv. around 3 years old. have white dots on the screen. Payed a lot for this junk tv.

mikechamb606,

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.

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.

Shut off

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.
