VIL Posted May 15, 2007 Share Posted May 15, 2007 Just an outside chance someone might be able to help? I have a Samsung SP50L7HXX DLP TV that I have had for about 20 months from new with no problems at all. However, during a TV program last night the TV just went off with a `popping sound` losing sound and picture! It then went through its start up cycle automatically (with a strange internal buzzing noise that happened a couple of times) and the picture and sound returned as normal. I left it on for about half an hour and it all seemed OK. I then turned it off for a few minutes and then back on and this time only got sound, no picture! I then turned it off and on again and got both sound and picture back OK? Does anyone know what may have failed in the TV and recommend what I should do next as its now out of manufactures warranty? I have posted this on the avforum but no responses as yet, I have also spoken to Samsung who are useless but suggested it could be the PCB but want to wash their hands of it as its outside of warranty! Does anyone know anything about DLP TV's and can help point me in the right direction? Link to comment Share on other sites More sharing options...
hiten55 Posted May 15, 2007 Share Posted May 15, 2007 iirc, the dlp "chip/processor" needs changing every few years - it could be that? apparently its not that difficult, undo a screw on the back, pull out the old chip, put in the new one.

VIL Posted May 15, 2007 Author Share Posted May 15, 2007 Cheers Hiten, I am guessing its something like this as the whole thing only has a few component parts. Its definately not the bulb and the colors seem OK so I guess its not the colour wheel either and equally the mirrors seem to be opperating so I assume its the PCB as Samsung suggested. But I am no expert on this stuff so it could be any of these or non of them? Problem is diagnosing it properly and trying to get the component parts. Its seems almost impossible in the UK to get bits for them and I may have to go to the States? I equally dont want to spend a fortune getting a technician out who takes 30 seconds to pull out the PCB and stick in a new one! I hate technology.......!

hiten55 Posted May 15, 2007 Share Posted May 15, 2007 the processor cost around £100 iirc, so it may be worth doing. the manual shows you how to do it too i think, if not instuctions are on the web. beatiful tv's - be a shame if you didnt give it a go really cant remember where my mater was told to get the parts from but try http://www.partmaster.co.uk Link to comment Share on other sites More sharing options...
VIL Posted May 15, 2007 Author Share Posted May 15, 2007 Cheers Hiten Partmaster dont do them and cant advise where to get them from! (computer says no....sort of thing)! If you do find out where your mate got his bits from I would be very grateful. Cheers Link to comment Share on other sites More sharing options...
