Hello to all,
I recently picked up a hlr5067wax/xaa off a guy I knew. He told me it was broken. I figured I'd see if I could fix it. I got the service manual and started troubleshooting. I used the flow chart and there is some confusion. The temp/standby red led comes on when you plug it in. Then the lamp (green led) comes on after. The lamp bulb lights up and that is all I can see (what is being projected from the lense.. The screen is black with the light of the lamp bulb (no images or menu options). The color wheel also works. After about 2-3 minutes the bulb shuts off and the standby/temp led comes on. I put a jumper in for the lamp door switch with no change. I unhooked the dvi cable between the and the light bulb shut down immediately. I used the flow chart and it said replace the dmd board. I purchased a new dmd and there are no changes at all. I know there is a possibility in getting a bad board but, in the manual it says dmd board and then says digital board in one of the flow charts. I tried the pressure on the dnie chip with no change. This is where I'm confused. Thanks for any help in advance.

Sounds like the symptoms we see with bad digital boards. Look through the forum and you will see several discussions of these problems, which often have to do with bad soldering on the dnie chip. You can try applying pressure as others have to see if the symptoms are affected. If so, there is reportedly someone reflowing the chips rather inexpensively. You can also replace the board for a little under $200.

Thanks for the reply. I read through a few threads and I did try the pressure on the dnie chip fix with negative results. Now, the digital board is the one under the analog board? I mean the one with the hdmi inputs, etc? I want to make sure that i'm getting the right one. The service manual is a little vague in some areas. I also saw the the thread of the gentlemen in Minnesota doing the resoldering and that's awesome.

Yes, the digital board is on the bottom. If you got no effect from pressure, you may not have a digital board problem after all, but it would be my best guess.

 

[Mharris]

Would the digital board cause the problem of a blank screen (no on screen menu), bulb on, lamp led blinking, no sound. Nothing. I changed the dmd board as per the service manual and it's doing the same thing it was before. I tried bypassing the dvi cable with one to my computer but it just shut the lamp off when I unplugged it.

Add no control of the set to that, followed by shutdown, and you have the symptoms of mine after it went from more minor and intermittent symptoms. It was fixed with a new digital board. Again, it is hard to be certain, as there are so many different ways that you can get similar symptoms, but it does sound like the digital board to me.

 

[Mharris]

What you added about no control and shutdown is exactly what it's doing. Is ok to post a link to my photobucket for some pics of the set?

 

[lcaillo]

If you think it will add something to the forum, certainly. You will have to wait until you you have a few more posts but you can use the post padding threads if you like.

 

[Mharris]

Ok thanks. I appreciate all the help.

you may want to send your board in to see if the solder reflow will take care of your issues.

 

[Mharris]

I tried putting pressure on the DNIE chip and it didn't do anything, So i'm guessing there is another problem with the digital board.

 

[Mharris]

here is some photos of what the tv is doing.

 

[Jason1976]

some of the people didnt have luck with the pressure ether but they had luck with the solder reflow. you never know. it maybe 40 dollars down the drain or it could save you lots of money.

 

[Mharris]

Just a question, but does the Digital Board (my part no BP94-02084A) control the onscreen display menus?

 

[Jason1976]

it's like the main brains of the tv it can keep the onscreen from coming on but even when it's messed up lets say with the green plaid the menu shows up just fine and look normal.

Hopefully i can figure this out. I changed the DMD Board out with no luck. It's doing the exact same thing it was before. I'm gonna change out the Digital Board and hopefully that help. Further investigation in the factory service manual (with the symptoms the tv has) says to the digital board more than to the DMD board. The flow chart says digital board so we'll see what happens. A read a bunch of threads and there more problems with the Digital board than the DMD Board. I just followed the manual and replacing the DMD Board didn't fix it.

 

[Jason1976]

well i would of said to replace the digital board first. that or try to have it reflowed since its only like 40 dollars and if it works it saves you money if it doesnt work then it will cost 188 dollars for a replacement board. so ether way you would still have less into it then paying a repair shop. well even if you pay for a reflow and then have to pay for a board it would still be less

I found a repaired and guaranteed digital board for 155.95 plus shipping. It will be here tuesday or wednesday. So I will put it in and see what it does. Hopefully I can put a post up here about my working tv. If anyone needs the info of the board post here. (I actually returned to the website and I bought the last one) but I have this I found on the website.

Maybe just another option to repair the boards.

thats cool another place with boards. so far people have had great luck with the 40 dollar reflow counting shipping. but if that doesn't work this gives them another option. but it's not in stock now. it says sold. it must be a used board. also some parts cost more then going right to www.samsungparts.com when I was looking.

I think the good thing about this one is that he can test the board and repair the parts that need to be replaced. That way when you get it back you know it's fixed. I'm not saying the guy at JDE is bad, I just remember reading he has no way of testing the board at the repair.
