Replaced bulb but tv comes only comes on for about 10 to 15 seconds then shuts down and red light flashes

I replaced the blown bulb and the tv worked for about 12hrs then shut down. I thought the replacement bulb might be bad so I exchanged it for a new one. I installed the new one and when I turned the tv on it still shuts down within 15 seconds and the red light flashes. If I turn the tv on with the bulb out of the tv it doesnt shut down. The manufactured date is May 2005.

    Well I know that the problem is the thermal reed switch. It's attached to the heat sink (along with a small fan) that is behind (I believe) the DLP Chip. If I unplug the thermal reed switch and jumper the plug going into it the tv works just fine. Also when I measure the reed switch it's open. My problem is trying to find the switch. It's made by a company named Tokin. Tokin seems to be part of NEC. I have found a few companies that sell in large quantities. Anyone know where I can buy just one?

The problem could be in dad board on top on the light engine.Any problems with the DAD board or the light engine will cause the unit to go into shut down. Replacement of the light engine usually includes the dad board. I know for fact that a number of Samsung DLPS have bad light engines and the use Texas Instrument LGs. You should have this verified by a professional technician. These light engine assembly's can be very expensive. Scrivitron

It sounds like you have a bad ballast board, or possibly the power supply going to the ballast bulb. I'm afraid that if you do not have the repair experience on solid state TV sets, you will need to contact and authorized Mitsubishi repair center. Good Luck

    You have a bad ballast in this set or the power supply going to the ballast. There is I'm afraid, no magic fix. You will need to test the voltages to the ballast and if they are good replace it. if they are not good, you will need to troubleshoot the power supply.

Tv comes on for a few seconds then starts to blink on screen then cuts off with red light on stays on

Hi Kenny
Being a projection device... Which most TV's aren't ...
You need to break the fault down into the Projection Section or the TV Section.
Or Power Supply Section
Projector bulb blown, overheating etc.
Power supply sensing overload or fault then automatically shutting down.
TV Section may be OK
small internal LCD screen is projected by lens.
Check internals.
Happy Troubleshooting

I have a Sony KDF-55WF655 and the bulb blew out and I smelled something electrical burning.

3 blinks is indicating that the lamp door cover isnt making contact so the lamp door cover is either attached wrong or the switch is defective.

Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the...

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

I have the 50" SXRD XBR1 grand Wega; This has been a great set for 3+ yrs. A flashing red light promted me to replace my original buld (this site). I now still have a flashing red "power" light, shuts off...

Its the fan that cools the bulb. Try turning on the tv and look at the fan to the rear of the bulb. If the fan is not spinning that is your prblem. The tv has a safety switch that will cut off the tv if the bulb gets too hot. I was able to tap my fan with a pencil and get it spinning, but that is just a temperary fix. After a while, you will find the fan will stop working all together and it will need to be replaced.

Tv Shuts off occasionally 1min upon power up shows red lamp light

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
