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, 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.

Have seiki television model number se391ts that was hit by lighting and will not come on, have replaced the main board and power supply board,can anyone please help


I worked as an electronic tech for a decade. Anything hit by lightning will never be reliable. Even if you can get it to work, one thing after another will go out. Get a new set--it's not worth trying to repair and they're pretty inexpensive.

Dlp tv color goes fuzzy and green


Its probably unrelated to lamp, take the lamp out, try it again and look into the lens, if its still very green the projectors electronics are failing. The projector generates pictures as 3 streams of info Red Green and Blue. It looks like the projectors red and blue electronics are failing, but the green is working.

No I do not. There is no lower cost, I wish there was. I repair DLP sets and have yet to have a customer replace the Light Engine due to the cost. That is why mfg stopped making them and also due to better technology. LED set is the way to go with 240hz.

Samsung dlp 61inch light engine


Most of the DLP parts suppliers are selling the entire light engine assembly complete with the color wheel also. Most places start about $400.00. I don't recommend doing this because of the reliability factor with DLP sets are not the best.

It is dlp tv that has one lamp as back light source. Yellowish tint is problem of Optical Block Unit (commonly known as light engine) that will be replaced to fix it.
Local tech will help you in optical block unit replacement because it is purely job of qualified tech.
Thanks.

Hitachi 50v500 blueing problem


I am not expert but before you go to a lot of trouble, read all of the post on the infamous "red cloud", "red blob" and "blue streaking". In evey case, it appeared that the light engine was the problem. We just had our light engine replaced and the TV looks perfect. We dealt only with Hitachis Customer Relations Department 800-654-7013. You will have to have a certified tech come out and diagnos the problem. Hitachi will then call and verify, with the dealer, that the problem is a defective light engine and will send out a brand new one.

We were told the part cost around $1500 (Hitachi covers that) however, they will ask you to pay for the install. Our install cost $400. Worth is to us as we paid $3600 for this set 3+ years ago and we have loved this TV. When you first call Hitchi, they will act like they've never heard of this problem but they will give you names of certified techs in your area. Once the tech confirms that it's the light engine, Hitachi will own up to the problem and send out the part.

You really should only deal with Customer Relations ( I listed their 800 number above as you will be chasing your tail so to speak with their regular customer service department. Good Luck!
