Check your power supply, it sounds like you have a bad cappacitor

I’m happy to help further over the phone at https://www.6ya.com/expert/joshua_ac64e182ed26f66d

be more specific. no power? no image? no light? if there is no led lit, power supply problem. if the led is on but the fan doesn't turn on when the power is pressed, either the dc fan is seized or a board level fuse is blown. if the fan won't turn on, usually the light won't either. if the fan is on but not the light, the lamp may be blown. if all is on and no picture, check your inputs.

Hi there,

This model as 3 LED indicator lights:

1) Power/Timer 2) Status 3) Lamp


If "STATUS" LED is blinking RED:

1) Internal Fan has stopped. These tv's require fans, to prevent overheating and causing damage.

If "STATUS" LED is solid RED:


1) Circuit failure (short)
2) Disconnected DVI cable, chassis to engine
3) No LAMP-EN signal from Engine to turn the lamp On.
4) Ballast UART communication problem.

If "LAMP" LED is solid RED:

1) Lamp Failure - Lamp failed to turn On.
2) Lamp is broken (e.g. burst or blown)
3) Lamp turns Off during P-ON

There is no data relating to TIMER LED being solid RED.

Hope this helps.

Cheers,

Scott

OR YOU MAY GO TO THE SITE (freepatentsonline.com) search the brand of the device....GOODLUCK.

i have the exact same error with same projector. did you manage to solve this?

my status led blinked red 6 times indicating a "lamp error" which wasn't helpful. i also tried removing and replacing lamp but didn't work.

Sounds like one of those problems only cureable with expert knowledge of for example Chroma feed , Lcd function , lamp luminence, not to be a killjoy but it sounds like this is one for the engineers an estimate should be free and even if you dont have it fixed you'll know whats wrong if you want to do it yourself providing you have adequate training of course ....

Hi
if the status light is blinking red in 4 sec interval it means that there is something wrong with cooling system. you shold check if there is a thermostat failure or if there are any switches that are not turned on. i suggest you to open the device (using screwdriver) and check if there are any switches broken or damaged.

i had pretty much the same problem (one second interval). i took off the cover and there was a broken switch and i just short-circuit it and now it works

Sorry for my english

Re-check the lamp door alignment. If the door is not installed properly, the interlock switch will open causing a no start condition. Also observe the red LED on the front panel. When you turn on the TV, a gree LED will blink on and off until the image appears. If the image fails to appear the green LED will give way to a red LED that will flash a specific number of times in between pauses. 3 blinks means the door is not installed correctly. 4 blinks means that a fan has stopped working, etc.
