Seems to be a possible heat problem, are all fans working and clean, is the tv surrounded by objects that could be blocking airflow or excessive dust, or smoke can damage alot of internal componants. Check all inlets and turn volume down to hear if fans are operating. May be something besides, but I would check the heat issue first.

After set shuts off, wait till the fans stop. Then press menu and input at the same time. The set will flash a 2 digit code. count the flashes. it could be a 2-6 or a 3-7 for example. then post that and that tells us where the problem lies.

Lights flash then powers down.


Before read this, keep in mind that this is not your model and parts are not the same. This is just to let you know the steps to take. Sorry don't have the schematic for your set, but maybe this will help in checking. I'm Ex-Army myself and Veteran of OIF and OEF.::::1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V on the Power PCB (part # 930B921002) 4.

Mitshubishi WD-62327 TV will not turn on and no sound. TV made a interference sound and shut off. Tried to turn it in the morning still nothing. Replaced lamp/bulb still nothing. Red light is on (not...


If you have a voltage meter there are some things you can check.
Unplug the unit and remove the back cover of the set. Then Plug the unit back in.
You will need to tape down the lamp safety switch in order to do these tests.
Here are all the failures that would give you a lamp error and what to check.
Cause 1. Unit powers on and works properly for a while then shuts off with a red lamp led(lamp error). Suspect bad lamp and replace.
Cause 2. Unit does not power up correctly and you have red lamp led(lamp error). Check the lamp enable line at connector J14 on the back of the light engine. If pin 6 does not switch to 5 volts after turn on, but your 12 and 5 volt supplies are good, then suspect a defective light engine.
Cuse 3. At power on the lamp turns on and off 3 times and then the unit shuts down with a red lamp led(lamp error). You have a defective light engine.
Cause 4. Unit does not turn on correctly and you have a red lamp led(lamp error). Check for 12 volts at connector J9 pin 4 on the light engine. If voltage is missing check for an open fuse F9A09 on the power supply board. If it is open, then you need to replace the fuse and you still have a defective light engine.
Cause 5. Lamp enable line at connector J14 pin 6 on the light engine does go to 5 volts at turn on, but does not drop back to 0 volts after 5 seconds, but your 12 and 5 volts supplies are good then you have a defective light engine.
Cuase 6. Check for 5 volts at connector J9 pins 1 and 2 on the light engine. If low or missing check Capacitors C9A37 and C9A38. Values are 3300MF/10V. Replace capacitors if defective.

This is all I have and I wish you luck.

My Samsung 60 inch DLP TV turns its self off several times an hour. Eventually is stays on. What's the problem?


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.Have a bless one!

Bad Bulb?


the pins that protrude into the lamp compartment have a tendency to get out of alignment where the lamp will only make partial contact. It sounds like what youre describing.

Tv powers on then ''clicks'' off


After the lights on the front of the tv settle down, push and hold the menu and input (or deivice) buttons for 5 seconds. Now count the number of times the LED blinks and follow these instructions.
Cause #1 1. Self-diagnosis error 4-4, check for proper seating of the DVI cable between the FMT PCB and the DMD (Light Engine). It may be necessary to disconnect and reconnect this cable to insure proper connection. 2. Self-diagnosis error 4-4, check for 3.3 volts DC at connector J-9 pin 8 on the Engine Driver PCB, if missing check F9A06 part # 283P128050 on the Power PCB if this is open suspect the 3.3v regulator circuit on the Power PCB part # 930B921002 3. Self-diagnosis error 4-4, check for 3.3 volts DC at connector J-9 pin 8 on the Engine Driver PCB, if missing check F9A07 part # 283P128050 on the Power PCB, if open suspect it to have been opened by the Light Engine part # 939P977020 4. Self-diagnosis error 4-4, if the 3.3 volt supply at J-9 pin 8 is good and the connection on the DVI cable between the FMT PCB and DMD are secure, suspect the Light Engine part # 939P977020 5. Self-diagnosis error 4-1, suspect the Power PCB part # 930B921002

WD-62327 Lamp


OSRAM VS. PHILLIPS
This is about buying replacement bulbs for the WD62327 TVs.I dont know about the other models but I purchased a PHILLIPS replacement bulb and it worked for about a week and then those dumb flashing lights and no TV. I did some research and others were saying that you had to replace some condensers. Shop would do it for 600 dollars..Well i sent the bulb back and bought an OSRAM replaement bulb. The TV is now working perfect.
