Sagem axium 50" DLP problem

My beloved 50" tv has gone on the blink, problem is when i switch it on there is a whirring noise as if trying to start up, the light stays orange and then just goes back to red in standby

is this a common prob that is easy/economical to fix?

If your tv is like the HD-D45 that I have, there are 3 LED's: the power indicator (red when the tv is in standby), the lamp indicator (usually off) above it, and finally the temperature indicator (also usually off) above the other two.

If you can be a bit more precise about which LED's are flashing/on, and for how long, we'll have a better idea of what's happening.

guitarman66,

tanks for your response, i originally thought there was a solid orange/yellow light when trying to switch on, but it actually flashes

it is the power light that flashes, it sounds as if it is trying to start up a few times and then gives up, then it goes red again in standby mode

If your TV only has one LED that flashes different colours, it sounds like it might be a Sagem HTD501, not a HD D50. How long is it since the bulb was replaced?

If you remove the lamp assembly, look at the right hand side of the hole where the assembly was, there should be a hole about 20mm wide. Inside there you should be able to see some coloured glass, this is your colour wheel. Does it appear to be intact?

Does the bulb come on at all during the startup? If you have the front plastic panel removed, you can see if any light comes out of the base of the light engine.

Let us have a bit more in depth info, and I'll give it a shot at diagnosing the problem.

Doh I should have posted here. I have a 501 same problem, but only little green board with 2 contact points in bottom left of bulb area.

just need to know what to short with and how ( would also be good to know what was on the lamp unit that is the proper way it should happen) ?

Cripes, now that is a question. The first HTD501 I worked on, there was no attachment on the lamp chassis, I simply clipped a paperclip over the contacts on the green board, and that fired up the TV. The second one I had, that had a small circuit board with a resistor on it, but no fuse. Again, I simply shorted the circuit briefly, and then the TV worked quite happily after I replaced the colour wheel.

I think I understand what needs to be done.

The circuit need to me made to reset the counter but broken again to let the counter count.

This needs to be done with lamp in place.

So my action needs to be, put it all back together with contact points bridged, and fire up the old beast, it should then turn on and give a picture, turn off, let cool and remove bridge. ?

bridging the 2 contacts sounds easyer than it is to actually do, or it is not working lol.. using a bit of copper wire so does not have the spring of a paper clip.

did you losen off the little circuit board ?

:) silver foil for the win, now do i leave it in there is the big question?

still got a one inch wide darker stripe down the right hand side of the screen which you can see picture behind but would be nice to sort out one day.

Thank you for the help MrFluffy would have given up without it

Leaving it in might be OK, I know I ran my first set with the contacts shorted for a couple of hours, with no discernable problems, but removing the short didn't have any appreciable effects either.

The black bar down the right hand side is most likely from a misalignment of the mirror tunnel inside the light engine. It's curable, but not a task for the faint hearted. It is also possible that your front mirror has shifted, but you probably wouldn't see the image in the dark part of the bar if that was the case.

Let me know if you want to attempt the mirror realignment, there was a post on here about 4 or 5 months ago, which had some great images showing the cause of the problem.

Removed silver paper, all ok still,, dont think i will worry about the stripe, might have if it had been one of the bigger mirrors that needed adjusting.

I saw the posts re curry's, they just told me tough when i complained about not working with sky hd or dvd players that did not have component output :(

Thank you again for the help, a four year old will be very happy to see "oggy and the cockcroaches" again on the big screen

I have recently inherited a Sagem Axium DLP50 etc., it came without any instructions at all!! I had it working about 2 weeks ago in various formats (re sources) but last weekend (10th Sept 2010) it decided not to work. The power light LED comes on red when switched on, but on pressing the handset button the light turns to flashing green and won't budge from that. I thought it was the main bulb so I bought a new one (expensive) and fitted that today, but the same start up with a constant flashing green light. Has anyone out there got any reasonable advice for me re my next step? I do like the machine but it has got me baffled, thanks in anticipation.

I cannot remember the codes that the bulbs falshing mean, but the manual is downloadable, thats where I found out about the red led next to the on off led, if i can find the link i will post it

First up, which model of TV is it? Is it the older HTD501, or the newer HD D50. The HD D50 has three LED lights on the right hand side of the TV, the HTD501 only one just below the screen.

Can you also give the sequence of lights, with approximate timing for how long each phase lasts.

'Raving' many thanks for the swift reply, I've now down loaded the instructions but the version I've now got is slightly different to the model of Sagem that I've got but it's a good start, thanks again.

MrFluffy, the Model TV is: Axium HD D50H G4-T/2, the sequence of 3 lights and symbols are on the front Righthand lower corner (from top to bottom) a temperature symbol - which hasn't lit up at all, then a symbol which looks like a black sun - this hasn't lit up either, lastly the Standby light, which comes on RED when the power socket is turned on. I usually leave this in standby for about 30 seconds before pressing the hand set standby button, the RED light then turns Green/orange and starts to flash on and off every second. That's as far as it goes at present. A couple of weeks ago it would just start up on pushing the hand set standby button. I hope this is okay.

Well, you've got an error code that's not in the manual. I'm impressed :D

Does the same thing happen if you use the standby on the panel on the right hand side of the TV?

Unfortunately it is exactly the same if I use the buttons on the panel on the side of the base unit. When I had it working there seemed to be a fan or something like that working in the base unit that started up which I thought would be there to cool the lamp but as I don't get to that stage now I suppose the fan wouldn't start until the lamp was working! I'm sorry I can't be of more help. regards

hello mrfluffy i have the same problem as you described here, the bulb does not come on now, there is no light coming from the side of the tv and i have the bottom two led staying red after trying to turn the tv on from standby, so i know that its not a temperature problem, can you please help in anyway you can, or give me some advice on where to start fixing the tv

thanks

It sounds like either your bulb has died, ot the TV thinks it has gone past the 8000 hour limit, and therefore should buy a new bulb.

If you remove the lamp assembly from the TV, there should be a small fuse on the side of the housing. If this has blown, then your bulb has gone past the aforementioned limit, and you ought to start to think about replacing it. If you replace the fuse with a quick acting 315ma 250V fuse, available from Maplins for a couple of quid, you can reset the time, and continue using the existing bulb.

If your bulb has shattered inside the assembly, then you will obviously need a replacement immediately.

Hi all,
I've been in touch with Sagem customer support. I told them i changed the lamp and fuse, but still no picture. They then suggested either .1. The optical engine is faulty. 2. A problem with the colour wheel or the formater card.
It makes no sense to me ! Can anyone out there help with some plain speaking?? Should I go down to local tip ? regards
Sparky:)

It's not one of the usual faults I've seen on any sets I've worked on. I'd have to suggest scrapping it, or selling it for spares on Ebay. An economical repair is not really going to be feasible.

Don't like to admit defeat on these TVs, they are usually fairly easy to diagnose, but yours has got me beat.

Mrfluffy, Thanks for your swift reply, I must say that I'm pretty fed up with the whole issue. The picture/sound I was getting was really good. I know that these machines are old and may be outdated, but I didn't think the first fault would mean dumping it! But many thanks for your interest and advice. A local independant TV specialist wasn't interested in even looking at it! The reply from Sagem, although very quick, means nothing to me at all, other than they suggested I consult with Comet as they still stock their products. I won't be doing that!! Thanks again.

Hi guys,

My 50" dlp has finally died, now I know there is a lot of good parts, and my question is where is best place to sell for spares as i know colour wheels etc are sought after?

My Sagem axium 50" DLP has gone dark..the timer has kicked in, I have taken the lamp out and can see the filament is okay on the lamp. I cannot see any fuse, but when i removed the lamp casing, there is a small 1cm (about 1/2 inch square in old money) circuit board with two electrical contacts with the wording Lamp safety BO.
Reading the responses above I am trying to establish where is the short circuit/ reset applied to reset the counter. Any pointers..
