Replace blue convergence amp STK392-040 with OEM first
quality ONLY = no generics ! I use Panasonic part number
C5AA00000107..........................................T.

This sounds like an o-so familar problem. It sounds like the Switching IC or the MICOM has failed

If all connections have been checked and the lamp is confirmed working, then I'd agree with the tech. Sorry for the bad news, especially since I know it's not a cheap repair :(

Digital board controls all video it could be the DM also as that powers the digital board.

I would wait to see if it happens again.

Sounds like Light engine sizzle noise makes me think color wheel.

Does the image stay frozen on the screen while the audio continues? If so there is a common complaint with the Samsung DLPs needing new Digital boards. Hope this helps. I can post the board number and link for a replacement if the picture freezes with the audio still working. If the picture just drops off the color that would be your color wheel.Let me know if I can assist you further.

sounds like light engine to me

HLP, HCN HL-S The Start-up Problem or/and
3 LEDs in the front blinking.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

usually if you had set for a long time its the the screen thats burnned i believe theres not much you can do but replace set

You don't - you would have to replace the entire module unless you have an expensive smt station.
What you're describing is the logic main board and possibly the dmd board as well. Something we call a cascade failure. I'd strongly recommend you take it to a qualified shop and have them do the repair. I can assure you it won't be an easy task for the shop either...

this is most often caused by a faulty lamp or faulty ballast. try resetting the tv by unplugging and leaving it unplugged for 5-10 minutes or so, plug it back in and check it.

you should be able to find the replacement parts via partstore.com

ballast is part number BP4700017A
lamp is part number BP9600224A
compatible cheaper lamp part number BP96-00224ARL

hope this helps,

remove the back cover u will see the fans one for the ballast and the other for the lamp

Sounds like a door switch is not making proper contact--or has been damaged. Check the lamp door switch and see if it is properly seated and the pin on the door is hitting the leaf of the switch.

You need a color wheel--common on these sets. Get a real phillips bulb and you should be set for awhile. The cheap generic bulbs are fine to get you through a few MONTHS....but NOT much longer. . An E22H-120/132 watt lamp is correct--and if you can replace just the bulb-(NOT hard at all to do) it will save you a LOT of money.

just from personal exp the easiest thing to do may fix or at least make it better. if u see puffed and leaky caps on power supply replace capacitors. if really dusty clean. both previously mentioned and both helped me. my tv was completely dead and replacing caps got it to power back up and work. it takes two trys to come on but works great so far. then i cleaned every nook and cranny with a small vacuum hose and different size/angle brushes that could be attached to hose. i only took out the psb board with caps and didnt touch anything in there that i could mess up. just cleaning helped enhance the colors. right now this is the best picture ive had on a tv and it was completly dead when i got it.

Check all your input cables & be sure they are snug on both ends, also check all your wiring connections inside the TV. you may have not gotten something back correctly or properly.
