Status light is blinking red, power button orange nec vt700


Hello
Look at the number of blinks of the status light.
[1] If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.
[2] If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.
[5] If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

Replace the 2 bulbs. Unit powered up correctly and turned on like normal. Then Lamp1 and Lamp 2 indicator lights blinked (Indicating Start UP). After some period of time, it switched to Red 6 times blink...


1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.
i have nothing on 6 ligths go ahead reconect and check for proper count. hope this information helps.
Best of Luck.

Temp light flashes tried unplugging it for a few minutes turned it on tries to power up but then power , lamp , temp lights flash for a few seconds then it shuts down and temp light stays on


It sounds like you have a thermal issue. The TV is getting too hot or the Thermal Fuse is bad. The thermal fuse detects the temperature in the TV and tells the TV to shut down if it thinks it is too hot. Most likely caused by poor ventilation or clogged fans from household dust. Try moving TV away from wall or cabinet first, if this does not fix the problem, clean ALL the fans in the TV. If problem still persists, replace the thermal fuse.

Turns itself off after 5 seconds of run time. will not stay on, cooling fans work, lights up screen and shows picture, then shuts off. light flash on front right corner.


Either lamp is failing (not covered under any warranty), or the ballast has failed. Or it may be a problem with the power supply, or even the fans... What is the picture next to the flashing light? If it's only the lamp light, then either lamp or ballast, if temp is flashing (the thermometer), it will be fans, temperature sensors, main board or power supply.

Sony KDF-50WE655 will not power up. Red blight blinks 4 times


4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

Blinking clean light


If the clean light flashes 7 times, pauses, then repeats...

When the dishwasher doesn't sense a water temperature increase, it will stop working and lock the functions (clean light flashes 7 times, all buttons are non responsive). It does this as a safety in case the element is broken and feeding electrical current into the water.

To resolve this you will have to reset the console. Do this by closing the door and press these buttons in sequence...

-high temp wash
-heated dry
-high temp wash
-heated dry

...all the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cycle finish (1-2 minutes).
You should now be able to run the dishwasher as normal.

If the issue returns, you could have a problem with the heating circuit (ie. element, thermostat or wiring). It rarely happens but it could also be the door switch not engaging properly when the door is closed (slightly bend the door latch down making sure it doesn't hit the door when you close it).

Temp lite blinks


Your ballace is most likely out. If not that your light engine is going out. You may be able to get a rebuilt one from www.vancebaldwin.com it will come with a new fan, and ballace.

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.
