Hello, my name is***** be happy to assist you.
Please allow me to ask you a few questions to diagnose the problem.
- What were the original symptoms in TV that prompted you to replace DLP chip and lamp?
- What light is red as TV has three lights on front?
Thanks.

White spots all over the screen.... Which I was told was due to a bad chip
Customer: replied 1 year ago.
Once I replaced it the TV wouldn't turn on I would just get a red light.... I was told I had to replace the lamp
Customer: replied 1 year ago.
Middle light
Expert:  Shahid replied 1 year ago.

OK, those thee lights are labeled as Lamp - Status - Timer/Power.

I need to know which one turns to red and is it solid red or blinking?

Thanks.

The status
Customer: replied 1 year ago.
The status light is red
Expert:  Shahid replied 1 year ago.

Flashing red or solid red?

Customer: replied 1 year ago.
Solid
Expert:  Shahid replied 1 year ago.

OK, solid red status light indicates either DVI cable is unplugged/ misaligned that runs between chassis and light engine.

OR ballast board connector is unplugged. Please unplug TV power cord, recheck all the connectors/ cable that were removed during repair to make sure all are plugged securely and tight. Replug TV power cord and press power button to see if TV works or problem persist.

Please reply back with the result.

Thanks.

Lamp light blinking orange
Expert:  Shahid replied 1 year ago.

OK, this error code indicate that lamp cover sensor switch is open as it get closed when place lamp cover on TV after lamp installation. If lower rear cover is off then lamp cover would also be off so look for blue lever switch near lamp housing area, push it manually which will close it so TV will think that lamp cover is on its place then turn On the TV.

OR put rear cover back on TV, tight the screws to engage the lamp cover sensor switch.

Please reply back with the result.

Lamp green status red

Status red
Expert:  Shahid replied 1 year ago.

So we are back to square one, solid red status light, is this correct?

If so, lets read the error code in TV in different way, Press the front panel “INPUT” and “MENU” buttons at the same time, and holding for 5 seconds will activate the Error Code Mode. The “TIMER LED” flashes denoting a two digit Error Code.

Example: If the Error Code is “23”, the LED will flash two times, pause, and then flash three times. This pattern will repeat five times.

Do you get any error code?

Customer: replied 1 year ago.
1-2
Expert:  Shahid replied 1 year ago.
1-2 code means 'no problem' in TV.
Please turn On TV and let it shut Off itself then try to get error code.
Customer: replied 1 year ago.
Still waiting for the TV to turn off on its own
Expert:  Shahid replied 1 year ago.

No problem, take your time, is the green light still flashing?

Customer: replied 1 year ago.
No I just get the red light (status)
Expert:  Shahid replied 1 year ago.

OK, please apply the error code read out procedure to get error code.

Customer: replied 1 year ago.
Is it supposed to shut off on its own
Expert:  Shahid replied 1 year ago.

Yes, sequence is, turn On TV, green light will start flashing that means TV is booting up, in case of any trouble the green light will stop and any other light will lit/blink that means TV is turned Off and in protection mode. Now we can get last problem occurred error code from TV.

Customer: replied 1 year ago.
1-8
Expert:  Shahid replied 1 year ago.

Thanks for the info.

1-8 error code indicates that light engine isn't getting 12V supply from power board and most likely PE or PE2 connector would be loose/ unplugged or misaligned. Can you please check power supply board of TV to see if such connector is plugged securely?

Customer: replied 1 year ago.
Omg I'm a women doing this for the first time lol I'm going to google images
Expert:  Shahid replied 1 year ago.

Sorry, who replaced the DLP chip and lamp in TV?

Customer: replied 1 year ago.
Me
Customer: replied 1 year ago.
But I just followed a video on YouTube didn't know the names of cables
Expert:  Shahid replied 1 year ago.

OK, AC power cord directly plugs in power supply board so follow the AC cord and check the connectors on that board, push them to make sure they are tight, then follow the PE2 or PE connector wires that will take you to other end plugged on light engine and push it as well, now turn On the TV and check if it helps?

Thanks.

Customer: replied 1 year ago.
Same error message I've unplugged and plugged everything back in and nothing
Expert:  Shahid replied 1 year ago.
OK, I'm out of ideas as what it could be, let me open the question to other experts to have a look, hopefully some one will soon respond.
I'm opting out, please do not rate my answer and leave it as it is.
Thanks.
