Top 20 Samsung HL-67A510 67" DLP HDTV Questions & Answers

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?

There are 3 fans with this set. Two of them are at top [inner side] and one in the light engine [inside the light engine]. There is no such button to reset the fan only. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/ Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done

I don't have a schematic for this model. So try this.. .when you open the back of the set, you can readily see two fans, a smaller one on the left, and a slightly larger one on the right. Fan #3 should be behind the larger fan in the front and slightly to the right of it. I would first see if it is operating. You can try to clean it with compressed air ensuring you rotate the fan in its normal direction and don't overdo it. If you can hold the blades so that they are not rotated by the compressed air too fast or at all. You might have to slide the main assembly out to get at it and there should be videos on youtube that show yours or a similar model. Anything further I suggest a trained technician.

Yes. The hard part is finding one! the screen itself should not be very expensive as with a flat screen for it is only a reflected surface and as long as the glass on the back is intact, the plastic front can be replaced.

Elisha,I was not able to find anywhere selling a replacement screen. May I ask why you want one? Did it get damaged? http://www.youtube.com/watch?v=-xUhOdzwLtw Did you have the unit looked at by a repair tech? What is the year of your unit and symptoms? The screen is just like a projector screen (DLP stands for digital light processing) It does not have pixels like a monitor or TV has and doesn't wear out or break unless it was physically damaged. If you could get one the cost of repair would likely exceed the value of the unit. If you have picture issues it typically is the lamp, color wheel, or dmd board or a defective capacitor. Have you registered your unit with Samsung with current contact info? You may be part of the class action suit that Samsung recently settled http://reviews.cnet.com/8301-33199_7-57376508-221/samsung-power-defect-causes-some-tvs-to-fail-and-a-class-action-suit-follows/ you can try the link to http://www.samsung.com/us/capacitorsettlement/ but it is not working for me.

First thing I would try is to remove set and a box or receiver if used from power for a while and then plug all back up--should reboot all units that way--cannot hurt and may very well help. Not just the set but any unit between signal source and set.It might also be a good idea to see if when the screen is black if the lamp can be seen--is it on or not?

Your DMD (Digital Micromirror Device) is failing, It roughly has 900,000 mirrors on the chip that move away or towards the light for shading. You may be able to find this board through Shop Jimmy or by simply googling dmd board for your model#

Have you examined the color wheel this set should have?look for (remove lamp as it faces that) any segments broken or missing.A color wheel also can have a high pitched or fan like sound but not always.check the wheel first.

Lamp is possible especially if the ballast was bad--it powers the lamp.Color wheel will usually display some issues--high pitched whine or fan like noise---with the lamp removed look where it faces--color wheel is there--any broken or missing pieces and it is the problem---The wheel is directly connected to the set---set will detect if wheel not moving or moving too slow etc and almost instantly turn the lamp OFF.

If a DLP suspected reasons are:LampLamp BallastColor Wheel etc.

Replace the optical engine. See my tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine for help with getting a new one and installation.

Thanks for using FixYa and for the great rating.

Tv it is not getting the tv stations broadcasting incomming signals.Make sure the ur pay CABLE or free AIR incomming broadcasting tv stations signal sources are good and than go in ur tv menu go into SETUP pick AIR or CABLE and rescan channels again.U should have no more weak or no signal message anymore.

Check the lamp if its more than two years old, otherwise check the color wheel.

That usually indicates that the optical block is going bad. That repair is usually 900-1100 dollar fix.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Generally, a DLP bulb lasts about 8,000 hours (if a TV is on 10 hours a day, every day, the bulb will last about two years). A bulb can last longer if it's used less frequently. Typically, a bulb in a DLP TV for household use should last at least three to four years before it starts to flicker and needs to be replaced.

Thanks!

Replace the Light Engine which incorporates the digital module also. approx $600.00 to replace.

DLP uses a light source, check bulb. Usually behind smmall access door on rear. Handle new bulb with gloves or plastic wrap.

here is the owners manual
hope this helps
