Red light came on tv , replaced lamp and still no picture

I had the lamp go out on my tv , i replaced the lamp and i restarted the tv , it made a sound as if a fan was going , then the noise stopped , the sound was on but no picture , then 2 minutes later the tv shut off and the red light status came on in the lamp section , is there something im not doing or did i get a faulty bulb ? Is there a reset process im suppose to go through when replacing the bulb ? Any help would be appreciated , thanks

    I unplugged it and plugged it in multiple times and i got the same thing , is there anything else it could be , the sound works and everything , i hear a sound like the fan is going and the fan stops , then after two minutes it shuts down and that red light comes on ,

  • babyboyyouth Dec 10, 2007

    Would this cause the red light to keep coming on ? This may be a silly question but will the red light come on if it is not detecting the lamp ? thanks for the help

  • babyboyyouth Dec 10, 2007

    Which one of these errors will indicate that the bulb is not secure or that it needs replaced ? Some tv tech just emailed me and said i may have pushed the ballast plug out the tv housing , i dont know what that is , and he said it may be a bad power assembly , does it sound like that to you ?

  • babyboyyouth Dec 11, 2007

    thanks , he called me last night at home and i pulled the back off the tv and put the lamp in , the plug totally came out when i pushed the lamp in , so i just have to get that part fixed , hopefully i can this weekend , i hope that is all that is wrong ,

  • babyboyyouth Dec 11, 2007

    yes , i can do it from my digital camera tonight , it totally popped out when i put the lamp in , i had to have my fiance hold the lamp while i plugged in back in , he stated that if that dont fix there is an issue with the 5 or 12 volt or something , i did that error test you sent me and it came up as 12 ,

  • babyboyyouth Dec 13, 2007

    I got the connection on the tv working , but the lamp will not come on , im getting error 34 now , any idea what that might be , tech told me might be bad power supply or ballast plug bad , please let me know , thanks ,

  • babyboyyouth Dec 14, 2007

    I did the system reset on the tv , not sure if i do it before i get the error or after i get the error , and as far as the ballast i dont know how to check for voltage on it , im cluelest to it ,

  • babyboyyouth Dec 14, 2007

    Tell me what you mean by making sure the ballast connectors are bent over , thanks ,

  • babyboyyouth Dec 14, 2007

    ok , please let me know if you find one ,

Look at it really carefully where the bulb plugs into the lame the connector is not sitting firmly on it reconnect it and make sure it's firmly connected to the plug.

    you can unplug it a million times and it wont help you have to get at the plug and make sure it on firm.

    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

    After replacing the lamp cartridge, when you power on the TV, the message "Did you change the lamp? PressENTERf or Yes , press CANCEL for No "will appear, press ENTER to reset.

    some tv tech just emailed me and said i may have pushed the ballast plug out the tv housing <<<<
    that is what i have been trying to get you to make sure didnt happen in the previous messages.

    That what i thought, is it possible to take a picture of that so i can show others email it

  • Cary Farah

    The first thing to do is a system reset using the recessed button on the front panel.
    34 Lamp did not turn on
    The most common is of course the lamp.
    If the lamp is new and the ballast connections are not bent over, then the next probable part is the ballast.
    I check for voltages and signals going to the ballast and if they are there, the ballast is bad.
    Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver
    PCB if missing replace the Power PCB part # 930B921002 3.

    ok, i search on error code 34
    found this to a simular problem you have
    The set has been in the repair shop... from what I understand, it was a
    bad IC9A20 chip (wherever that is). Replace that chip, reset to
    factory, center and align mirrors.
    that chip is the voltage regulator chip

    cables and tech said the capacitors on the formatter board has to be
    replaced. Part back ordered

If its a DLP with a high pitched or even fan like sound it is the color wheel--Mitsubishi does not sell them as a part---you would have to replace the entire light engine (expensive and may not be available any more on a older set) .

My Samsung HLP4663W 46 in was making a buzzing noise for several months. I know it could have been either the fan(s) or the color wheel, but I never opened it up to determine which it was. Now the TV quit...

Great reasoning work! In fact, the lamp will not light if the color wheel does not spin-up. Fans will not stop the process of lamp ignition. Instead, a fan will be detected and a message will appear on the screen telling which fan has stopped. You need to have the color wheel replaced.

I own a Samsung DLP tv. It shuts off after being on for about one hour. It will restart but does shuts off again in a few minutes.

Your Lamp maybe going out replace it,also CK your Fan right behind lamp set will stop coming on if it is not running, Fan could be bad.Order Lamp on E-Bay I found lamps for 82.00 fixing to order one for My TV which is also a Samsung.Last TV I repair that did like that it was the Fan.But always remember lamp only has 5,000 to 8000 playing hours.

Sony KDF-E50A10 50 in. HDTV LCD Television has a ringing sound like a cellular phone whenever the TV is turned on. I have isolated it to near the projector. I have taken out the projector and it still...

There are more than 1 fan in the set; however, the last one to turn off is the lamp fan. The lamp fan keeps your lamp cool and helps extend the life of your projection bulb.

You could either replace the fan, or remove the fan from the set and give it a good cleaning (that's all it might need). However, be aware, fans that go bad in these sets will start to shut down your tv and decrease the life of your lamp. Be on the lookout for intermittent or sudden shutdowns, as those can definitely indicate a bad fan.

A friend of mine does warranty work for samsung ,name is chip call him if you need too! 256-778-0300, most of the time when lamp needs replacing set will not play,the fan behind lamp is there to keep lamp cool when playing ,DO NOT touch lamp if you do this will leave fringer print and lamp will burn your inprint on it when hot!!! then you will have to replace lamp ,they are not cheap.replacing lamp is fairly easy, besides i really dont think lamp is your problem,most likely it would be fan making noise.
