Samsung HL - Answered Questions & Fixed Issues

Each set is somewhat unique in terms of parts, could you please update this with the model number. With that I should be able to rpovide you with details.
Thanks,
Dan

You will actually get white and black dots , the black ones are tougher to see because of the color in the background , within 2 months youre picture will be fully covered with dots....I went through the Samsung website troubleshooting flow chart , and it led me to a bad Digital Micromiror Device , or DMD board . What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color . Samsung will not tell me the part number of the chip , they will only offer to send a service tech to my house .

I would use a program called testdisk which contains photorec. Also be sure to use a second drive to restore files too so that the original files are not over-written. After you recover your files you can see if the drive will format.

Do you mean you have power between the grounds of the HDMI ports...if you measure the metal part of the connector to frame ground you get a voltage reading?

you either have incorrect placed or bad avi cable lastly could be a dmaged main board in the TV since other connections such as hdmi work fine focus on the avi device your connecting and test it o another tv with the current cables i bet it is not the TV

hi sounds like dpl ic chip is faulty thanks

your problem is most likely not the Tv i bet you are using an air antenna arent you

Use Google or Bing and search for an HDMI to VGA with audio adapter. Be careful not to mistake the VGA with audio to HDMI adapter. They are not the same device and some internet locations have very limited descriptions and can be confusing.

Could be a bad/failing fan. Is the fan still vibrating? Is it making more noise then normal? Most of the time i find that a fan going bad and vibrating raises heck with the rest of the optics in the TV.

How much was it moved? It could have jiggled something loose or made an intermittent connection, try removing the bulb/lamp and put it back in to reseat it, it might be detecting a lamp issue due to a bad connection, or a lamp thats starting to fail, if you have a spare lamp you can try replacing it. If thats not it then it may just be something is failing due to age/heat in the tv and moving it caused enough shock to the part to go intermittent. Most commonly when a projection tv does this its a problem with the lamp, or the power supply board.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

You have a blown fuse on the unit. Needs to be replaced.

Hello... I would start by getting the correct lamp for the TV, and I would advise getting an original equipment lamp. The lamps and ballasts are matched by wattage and operating voltage, and a mis-match will at best cause early lamp failure. The sound you are hearing could be the ballast trying to ignite a bad lamp caused by a mis-match. I hope this helps!

You have a bad audio output IC in the main board, you have a couple options as long as you don't use the sound from the TV...one is order a new main but if it was me I would take the back off and follow the wires that go to the speakers and unhook that plug.

You might want to try blowing it out with air, I have a toshiba that has had a similar problem and that always fixes it for a year or so. The problem is caused by the small cooling fans on the circuit boards, they get clogged and don't cool the board properly. The startup problem is also linked to the fans, they must run at speed or the board shuts down. I used an air compressor and took the tv to the garage to blow it out, you will need to take the back off and blow it our really good, and make sure to get ALL the small and large fans really clean, mine has four fans. Hope this helps....GOD BLESS...Randy

first try re-seating the lamp by pulling it out and sliding it back in. You would need to take off right side back cover. Sometimes this can clear the error and may fix the problem altogether. If no, try clean All the fans inside the Television to preserve the life of the lamp.

The main board is more than likely the cause of the trouble. Time for a new TV.

renotify the samsung teck for more information and assistance

Hi Eloy, There is some short circuit further up in the power supply. You have tried what you could do. Let some Tv Tech do the job onwards. Or if you are handy with some basic electronics knowledge I could suggest something. Good luck.
