Bad light engine

Any suggestions on how to fix a bad light engine? My issue is similar to one another user has. Below is the description of what the tv is doing. It is a samsung HLN5076W.

The TV will be working fine then the picture will suddenly freeze in black and white pixels for a split second then disappear all together. I noticed one suggestion was a bad light engine assembly. Are there any other suggestions on how to fix that?

The check engine light is on, on 2003 Audi A6 due to catalytic converter, any cheap fix?

I've got a similar issue with an '07 Mustang GT. The description of the code thrown indicates a catalytic converter OR an O2 sensor. You might check out the rear O2 sensor if you have one. May be way off base but worth checking it out.

Pink splotches on white screen

I had a very similar problem with mine... You are correct, it is the optic block.. it will cost about a $1000 or so to fix. I chose to fix my 60" because I absolutely love these TVs. The Technology may be older but they are still great!!!!! (i.e. Instant refresh rate required!!!)

If you think you also have a dust issue just get a vacuum cleaner and clean the vents on the back of your TV. You can also remove the Front Panel... take out the lamp (make sure your TV is COLD!!! me on this) and vacuum what you can making sure you do not touch the back mirrors (located where your lamp goes in). You should do this every time you change the lamp at a minimum.

Light engine blue bad any way to buy parts or fix

The only fix is light engine replacement. Search google with UX27712R part number. There will be many sources. All are rebuilt engines. If consumer buys the part and installs with no success, part suppliers will bring up issues relating to damaged by user or incorrect installation.

After replacement there may be some alignment issues or faults caused by incorrect installation and assembly.

Experienced technician that has changed an engine before, usually under warranty, has had an opportunity to learn the correct way to do it in a shop situation with known reliable parts.

User replacing may have a "no start" or "poor picture" situation and not have the experience or skill to recognize a secondary problem, minor connection problem or defective replacement part. It is more complicated than a fuse, bulb or other minor part replacement.

DLP RCA HDTV is displaying bars from top to bottom of screen, with green tint. Is this the light engine going bad?


Thanks for using FixYa. This issue can happen due to a faulty light engine or due to a a faulty DLP Lamp. However, it can be an issue with the video driver card of your Card. I'll suggest to use a DVD player and check if the tint is still there. If the tint disappears then its an issue with the video driver card.
However, if it doesn't correct the issue its either a DLP Lamp or a faulty light engine.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Before performing any repairs i'll suggest you to try and reset the TV by unplugging it for 8-10 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.

TV with grey screen turns self off

This is an issue with the power supply. The capacitors used are faulty and you likely have to get a new board(about $400.00) or fix it yourself. LG's are quite east to disassemble.

You will be able to tell it is the power supply board due to the cable running from the plug to the board. It will look similar to this38376af.jpg

Next locate the bad capacitor, likely green and about the size of a quarter. You will be able to tell the bad capacitor by the bulge on the top.

At this point you can buy the new capacitor at a local t.v. repair shop for just a couple bucks or likely take the board to them and they should be able to fix it for 10-20 bucks. Unless you are decent with soldering I suggest taking the board in and having them replace the bad capacitor.
You will need a 2200µF 10V capacitor. I may suggest bumping to 2200µF 13-16V capacitor just so you don't have the same problem again.

Once the bad capacitor is replaced, replace the board and turn on the t.v. You should be good to go.

51" Magnavox projection TV

I had the a similar issue. My TV broke - no sound and no video but the power light was still on.

I gave up and called in a repair tech.

He fixed my TV in less than 30 minutes by replacing a bad IC chip. He informed me that this is a very common problem with the older Magnavox TV sets and that its typicaly the same chip that fails.

I spent over 300.00 for the repair. The parts cost less than 20.00.

To help others in the same boat I put together a how to guide and parts kit on .  I'm not sure if it will work for you but it may be worth a shot.

Hello Fliper,

These symptoms denote a shutdown circuit problem, and a problem in the section of the TV that provides High Voltage to drive the raster creating circuitry. In your case this would be the DLP related circuitry this would include the light engine (white light blub/Color wheel drive circuitry or LED array, DLP chip and associated circuitry). In any event if you are not planning on working on this yourself (which I would not suggest for this type of problem), Have a qualified TV repair technician come over and examine the TV and give you an estimate on its cost.

I would also tell you to expect it to be rather high since for your description of the problem it looks like a light engine problem, however it could be as simple as a blown bulb or LED array. The Technician will find that out.

I hope this helps,
Thank you,
