If the set will not boot up, you must verify the power supply. You have to look for the power buss and use a volt meter to check to see if it in specs. You will need the service manual and a high impedance type volt meter like that is used for electronics servicing.

I don't know all the model designs by heart. You would have to get the service manual or figure this out unless you can find someone who can tell you off hand where the test points are.

If the power supply is not putting out, you would have to replace it. These are difficult to service at the component level and usually don't pay to spend the hours of time and then trying to source the individual parts. Many of the components are surface mount anyways and you would require the proper service mount soldering tools and setup to replace them.

If the set is out of warranty, it would most likely be not cost effective to service it. The modern type sets no longer use lamps. The newer generation of LCD sets have a far superior picture than the DLP sets. I would strongly recommend replacement...

Sounds like corrupted software. A firmware update must make it right. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy Pull up older posts. Surf the site with patience.

SOURCE: Samsung DLP TV shuts off

Hello All, I may have an inexpensive solution to your problem. I had the same problem with my TV as well. It would shutoff by itself about an hour after it was turned on. The when I would turn it on again it would shut off after 5 to 10 minutes. Finally I got fed up. I knew it was not my bulb because the picture still looks good. I did here a buzzing if I would turn the TV on right away after it would shut off. That was do to the bulb recharging itself. I noticed the TV was extremely hot in the back. So automatically I thought it was the cooling of the set. All post I read keep saying the TV would last about 2 years to a year after a service. Which would be right because (most) service repair clean out the units before installing new parts. What I did was I opened unplugged the TV from the wall and opened unscrewed the back panel door. I used my Air compresser and blew out all the dust inside. ( A can of compressed air should do the job if you do not have a compressor) I removed the bulb and blew out the dust on the bulb as well. I did not remove the bulb from the housing unit. After I dusted the bulb and housing unit I reinstalled it. I keep my home clean but you should have see all the dust that came out. The dust covering the components overheat the unit which causes it to shutdown. It has been about 2 weeks and have not experienced any problems since. All I can say is give this a try and maybe this will work for you. This will only cost you about 10 dollars and 30 minutes of your time. This is better that Hundreds of Dollar in repair.

SOURCE: tv turns off after 5 sec.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

SOURCE: Samsung 61' DLP Color problem.

If you are using Component inputs, check to make sure that the Blue Video Cable has not backed out of its connecting jack at either end or the cable it's self being bad. If you are using HDMI I would suspect that the Digital Board being bad. It would be odd for the Color Wheel to cause the problem but cannot eliminate it as a cause. The Lamp would cause the picture to be darker but not cause a color to drop out.
I would call a professional to trouble shoot it unless you have the knowledge and the tools to do so.
Hope this helps,

How do i change bulb in tv


Hello
Your Samsung tV is LCD type. It has no bulb to replace as in DLP projection televisions. there is CCFL [Cold Cathode Flourocent Lamps] are the lighting devices, which are fitted just behind the LCD screen There will be more than 12 numbers of them, accroding to screen size. If these lamps do not light up; that is; if you do not get any backlight with your LCD TV, the backlight inverter board should be troubleshooted. This is the board that supplies high frequency high voltage to these lamps to light up. Check this inverter baord first. Repalcing backlight CCFL lamps is really a skilled work, as they are fitted inside the panel, and to replace them, you have to disassable the panel itself.

My screen went black but I can still hear everything I removed the back panel and the lamp does come on but still no picture


Hello
If there is lamp ON and there is no picture at all, the DLP drive IC on the main board has damaged. Normally, damage to this IC will also couse to DLP [Digital Light Processor] also may get damaged. A thorough check to your Tv is needed. As it is DLP based one, proper care should be taken to repair this set. If DLP drive has damaged, it will be best o repalce the porcessor board as card basis. Anyway, keep in mind that the circuit for this tV is very complicated, such that even an expereinced service technician will also take time to pinpoint the exact fault point. A very high quality multimeter is needed to measure the voltages at the DLP board. Moreover experience is a must to do work with this TV. As far as lamp il ON, there is no fault to its power supply board. The fault lied in the main board itself. If you are aware in electronics, inform me. I'll assist you firther. Otherwise get this TV repaired by any experienced service parsonal or by the authorised service center for Samsung at your town. Authorised service center will have all sophisticated testing equipements ot do this service and it will be perfect in all respect. OK

Picture suddenly went out and the lamp and temp lights in front circle are blinking.


Hi,If your tv is between 2-4 yrs most likely it's time to replace the lamp.If you hear continuous clicking it could be the ballast which is the board that powers the lamp.If you hear buzzing it could be the color wheel,which is a spinning wheel that creates the color on your tv.God bless you!
