Light engine replacement

Ok lets start. I am an electronic tech, but this is the first DLP set I have worked on. It cam in with the notorius red screen. Tried the memint and factory reset. No advaile, so order in an complete light engine. After replacing the light engine I now have an green screen..In the service menu you cannot adjust the drives or cutoffs. On the old light engine I could adjust these. Any techs have input on this..Or ask me more questions and I will answer them.

PPS I also saw that (from another post) you can hook up laptop to set? if so anyone know how..

Good Day, almost tech;

Give me some help:
1. What input are you useing, if any?
2. Do you have OSD or VIDEO??
3. Did you reinstall old 'LE' back into TV???
4. Did you double check the TV's Model number vs part number received????

Let me know, big IRISH.

Good Day, tech;

Let's suspect poor cable connections or pinched, BUT I have received bad light engines. Make sure you ordered the correct Part Number. There are two (models) of them; check Model Number, some are 50V500 and 50V500A.

What's your input to indicate red or green???

Let me know if this helpful, big IRISH.

Why does my DLP 60 inch Mitsubishi TV keep turning off and flashing a red light?

Your repair tech hinted correct. Although the bad connection will likely be in the power supply, it actualy can sit everywhere the power goes. Can be anordinary plug / connector with a little oxidatin, or a dab soldering point. Or perhaps a electrolitic cap, slowely dying.
Let the tech do his job. He has the tools, education and skills to keep your beloved TV alive.

Dlp red haze

Inside the light engine all the mirrors are probably fogged. If you attempt to clean them make sure, I repeat make sure they go back the same direction and place they come out of... let me know what you find out : Expert-tech / Sam

What causes the yellowish hue in the centre of the screen

There are several different types of projection sets: some use 3 picture tubes, red,green,blue--if this kind of set is what you have the coolant used in the blue tube is bad-----this type of problem leaves red and green which = yellow.

Most common in Samsung, Philips, Magnavox type sets.

If it is a newer set without picture tubes (a dlp style set) yellow in the middle of the screen would denote a damaged optical light engine.

Let me know brand, model number, date made----all are on back of set.

I own a Samsung HL-R5067W 50'' DLP. Set is about 3 years old. Recently I heard a loud pop while viewing, picture distorted, but never went blank. I turned set off. When turned on again a loud whining noise...

Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

Hi I have TV AKAI start projecting a red

rear projection tv can be crt or dlp, if crt, try to adjust red color using the customer convergence feature, you will find it in the customer menu usually under advance feature or video settings, some tvs will just give the convergence caption right on the menu listing. If this does not help then the tv might be in need of some convergence circuit repair, probably one of the power outs is damages and needs to be replaced. If it is a dlp if the red shade extends all over the screen or located in a certain area of the screen then i would have the tech check for light engine trouble, this is a common problem on some dlp systems.if i answered your question satisfactorily please leave your positive feed back. thanks

Zenith DLP-Projection tv 42"

Try this solution which I found on Fixya

This solution is for the zenith 56" DLP. Unplug the tv, either from the wall socket or the TV. While the TV is unplugged hold the power button on the TV for 40 seconds. This lets the excessive power drain from the TV. If this does not work call 1-800-243-0000. This is the number for their help line. This is the fix the tech gave me and it worked right away. Hope this helps and have a great day.
