I hate being the bearer of bad news, had the same problem, and I found out that the problem with DLP is that after so long, nothing that you do will fix it. A TV repairman offered me $100 for my set and I took it, that was 2 years ago and it still goes through bulbs and ballast several times a year. Now when i see him he always says I never should have taken that TV. It never plays long enough to sell it.
On a liter note: 4k si approaching $1000 now, that's the way to go.

SOURCE: yellowing spots on 52 inch LCD Mitsubishi display

have the store fix it you need a tech that has the right equipment to fix that. Since you say you replaced the lamp I assume you mean a LCD micro projector not an LCD Flat panel. There is a piece of equipment that a tech should have that can be plugged into the TVs circuit board and it can fix the spots with an electric pulse. I have seen in done on micro projectors in the store that i work by our techs. So my advise is have the store fix it before your warranty runs out.

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

Looking what i can do to fix. Have a Mitsubishi TV 3D DLP WD-73640, Replaced bulb, and still have the red LED flashing 6 times to the Yellow led flashing 1.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

What is causing the lamp to keep going out on an 82" 837 Mitsubishi TV?


If a OEM Mitsubishi lamp was used you likely have a problem with the Ballast that drives or powers the lamp---the two pin socket for the lamp goes directly to the Ballast.

I have a mitsubishi 735 series dlp tv. Has red blinking status light. The error code was 4 blinks then two blinks. Do you know what is wrong with it?


That's the error indicating the lamp/ ballast fan has stopped working. You can get the Mitsubishi lamp / Ballast fan 299P321010 used in the V39 series DLP televisions. It comes with installation instructions and is available from www.tvrepairworld.com under the Mitsubishi DLP parts category.

Why does my samsung tv cut off by itself after 1-2 min and flash a red lamp button?


A little explanation first- this model (as do most Samsung DLP sets) will try 3 times to get the lamp lit before the microprocessor will give up and then the 3 lites on the front will blink indicating a LAMP failure. This process takes about 1 to 2 minutes. In order of probabilty, the failures are:
1) A faulty lamp and/or ballast. REPLACE LAMP AND/OR BALLAST
However, a faulty lamp and/or ballast are not the only things that will give this blink code-
2) If the color wheel has a bad bearing and turns too slow or not at all, the microprocessor WILL NOT let the lamp light, and then give a LAMP blink code. A bad color wheel will normally have some sort of abnormal sound- a low growl or high pitched whine is common. REPLACE COLOR WHEEL
3) ALSO, if the microprocessor (on the DMD board) in its color wheel rotation detection or processing fails, once again the lamp is prevented from coming on and you get a LAMP blink code. REPLACE DMD BOARD
IF THE SET EVER COMES ON WITH A PICTURE for even a fraction of a second or though it takes many tries, the lamp and ballast are good. The problem must be either the color wheel or DMD board.
