Hi! Your lamp is nearing the end of its life and needs to be replaced. You can do this very easily yourself and your manual explains how to do it. It's two screws. Order it directly from Mitsubishi. The OEM lamp costs $249. Do not buy an aftermarket lamp from an online retailer. They are of inferior quality, normally do not come with the cartridge can damage your set and they usually cost as much after you add the cartridge.
Here's the link for Mitsubishi.

If the soda got into the inside of the TV it sounds like it has damaged the light engine. There is currently one on Ebay for $400. It unplugs and new one plugs back up. Do a google search with model WD-65733 and verify if this is your model. Otherwise look at the screen closely to see if the soda is on it. On the other hand if you get the light engine out you may see soda spots on the projector and you could just clean it.

You have a defective optical engine. The problem will likely progress but will not cause damage to any other part of the set so you can continue to watch in the mean time. 938P075020 is the part number for the engine but the price is around $1000 for the part. Call MITS consumer relations dept at 800-321-6993 with model, serial and date of purchase and they may cover some or most of the repair through an authorized servicer.

WD 65733 IS an HD TV.
The signal coming into is the key.
You must use HDMI or Component Input to translate HD to a TV.
Check the output resolution of you DirecTV box in its setup menu.

Hi Jackie,
This will actually $200 more or less depend on the technician. If the technician is come from the service center representative it will cost you $200 more but if he is a walk-in(not from service center) technician may charged you $200 or less. I would advice you to look for a qualified walk-in technician to save some money. You may ask your friend if they can recommend you an experienced one.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Easy one. Your lamp needs replaced. part number is labeled on the lamp itself and is easily accessed from the rear of the TV. Approximately 6" lamp cover removes with a few screws then a couple more for the lamp. Simply pull out and replace. Cost for the lamp is around $219. Make sure to replace with OEM parts.

Hi Kevin this type of problem needs to be serviced. What you see is liquid trap in the LCD screen that might damage other parts of the LCD if you wont fix it. If its under warranty call the Mitsubishi support.

Hello Eileen,

Mitsubishi does not have any software upgrades for the WD-65733. It's possible that you problem has been listed under the wrong model number, in which case, please specify the correct model number and I will be able to give details on how to upgrade the software in your TV - assuming an upgrade is available.

If you do have the WD-65733, please could you let me know why you wish to upgrade the software. It's possible that you have a fault or other problem which requires attention, however it may not be something that can solved with a software upgrade, even if one was available.

A component in the TV has failed, maybe a capacitor, but can't tell without looking at it. Would need to take it to a repair shop for diagnosis and repair.

If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.

the DLP chip is going bad you need to replace it to correct this issue

Mitsubishi... | Answered on Dec 19, 2010

You are not the only one I can tell you that. I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

green blinking light, tv will not power on

Mitsubishi... | Answered on Dec 05, 2010

The white spots you are seeing are a result of dust or dirt in the light asm. Mits knows about this as a problem. The inside chamber of the tv needs to be cleaned. If your tv is in warranty they will come to your home and fix it. If not it is very easy to damage the tv by trying yourself, start with cleaning out the chamber that the bulb is in, use compressed air to blow out dust and dirt, them on the sides of the tv are round flaps that will need to be removed and this will go into the main mirror chamber, be careful but blow out any dust or dirt you see on the mirror. I would have a repair tech handel this unless you are skilled in this area.
good luck
