Question about Televison & Video
Please help with my recent problem of the TV Magnavox 50ML8105D/17 Projection DLP HDTV playing normally (picture looks bright and clear) then after a couple of minutes of use the power cuts off and the error lamp indicator red light on the front display panel stays on (no blinking - solid red).
I can turn on the TV again but the same problem happens over and over....
Is the projection lamp going bad?
Thank you for your help and expert input!
I have the same problem my DLP TV would shut off after 30 minutes or less all red LED's. Solution: The fan on the lamp assembly was not turning at the proper RPM (bearing going bad) so it was going into overtemp mode. The original part number was a SUNON KDE1209ptv3 12v 1.3W I had a hard time finding one to match that spec. DIGI-KeyCorp (www.digikey.com) was able to cross reference it to a 3 lead P11034-ND part number (NMB-MAT model fba09a12L).
I Installed the fan and problem went away.
Remove the lamp from the lamp assembly
Remove the back panel.
From the back, slide the main circuit board to the left (loose one screw)
Remove the power interlock on the lamp assembly (2 screws)
Disconnect Lamp assembly cooling fan lead.
Remove the 4 silver slotted screws on the lamp assembly, 2 in the front and 2 in the back.
Carefully remove the lamp assembly from the rear. WATCH the Mirror.
Remove fan, cut leads and solder or **** splice on to the new fan.
Repeat steps for installation

I replaced the cooling fan located under the bulb. Problem was fixed.

Try cleaning the filter........sometimes it gets clogged and then the set overheats.

I had this problem 1x. It was on a real hot night (i have no A/C). I took a fan and placed it right at the vents on either side and solved it.

I replaced my lamp yesterday 3/26/08 and still have the same problem. I kept turning it on / off before I replaced the lamp. 10 or so tries and it would stay on. I believe this eventually burnt out my lamp. Fans are clean/ new lamp, same problem. Another forum I read mentioned a firmware upgrade? Any advice.

I had the same problem...I took the back panel off the tv and took a small desk fan and mounted it so it would keep the bulb extra cool...IT WORKED! I left it like this for about a week. It shut off only twice after about 4 hours of on time. I then disconected the small white ceramic sensor on the back side of the light. (there is a plug conecting it, just follow the wire to it) It has been about 3 weeks now and I have not had the tv shut off yet. (disclaimer...could start fire from over heating? try at your own risk.) If it works for you buy a new sensor.
