    My TV keeps shutting down. I can hear the sound, but can't see the picture. The power button is flashing LAMP, TIMER, and STAND BY. Is it the lamp? It is also making loud sounds - is that the fan?

Had the same problem. My son said the lamp door switch was too sensitive and proceeded to put a pad on the bottom left corner of the door to push the switch down further. Problem solved for me!

I have a mitsubishi 1080p wd-65731 just replaced lamp , tv comes on works fine for about 30 minutes and then shuts off , cleaned vents good , has good air flow light that says lamp turns red in the fr


Could be the fan. It will cool tv but could also be to much for tv to handle.
You can also try reseating the lamp. It may say ok but be wrong.
I have a Mitsubishi 5500 projection tv . have had the type of issue you have had and I have replaced a lamp as well.had to reseat the lamp three times before it worked without shutting down.
Hope this helps.

Sony Dlp, 46" shuts off, cools off, then turns


This is probably a heat issue (assuming you aren't the one turning off the TV and aren't having regular power failures). This TV has two fans to help keep the components cool; if the temperature increases, the TV will shut down to protect those components. Also check if the ventilation slots are blocked and clean the dust off them. (When you have the TV open, you can blow out dust as well - much like dust removal for a desktop CPU.)

For replacement fans, you can go here: http://www.partstore.com/Model/Sony/Sony/KDF46E2000.aspx .

I hope this helps.

The tv turns off by it self


Hi,
Your problem resides in two places, the A/V board and the main system control board assembly, as for the unit switching off and on this is an indication of a bad lamp, the unit has a lamp usuage timer that records the amount of time on the lamp, it needs replacing if it has been more or near two years as the lamp is only good for 6500 hrs of use, thats ruffly three years, The componet input not working is due to a bad switching IC on the A/V board, Replacing the Audio/Video board will solve the input problem. The A/v Board plugs into the main board assembly.

Apart from these the other possibilities are:-- 1)loose solder connections can cause short tracking. Get the board re-soldered to fix this issue. 2)faulty or bulged out capacitor causing short tracking.Get the faulty capacitor replaced to solve the problem. 3)the unit gets over heated internally and shuts itself.Keep distance between tv and wall and keep a desk fan behind the tv to keep it cool while you are using the tv and check. overheating can be because of internal fan problem.

Thank you!

This is very common with Samsung and is considered a overheating or lamp issue. cheapest fix before changing out the lamp is to unplug the unit after it has shut off its fans and open the back up and blow all the vents and circuit boards off with can of compressed air. Then remove the lamp to get to the larger fan that is behind the lamp, be carefull to not let the fans to spin when you hit it with the air because it will spin the fans faster than they are ment to spin, so gently place a finger on the blades just enough to keep the fan still and clean off any dust you see on the blades and area. Put everything together and give it a test run. If it stays on longer you know it was just to dusty to stay cool , if no change then try the lamp.

My tv turns off


Power issues (Tv True True (``````````` (``````````` 0 95250 95250 clip_image002.gif 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 True True (``````````` (``````````` 0 95250 95250 clip_image002.gif 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.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 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 & Engine disconnected. Sorry for the long answer but it was an open ended question.
