Hi Olamiposi
Modern Digital TV's are now Computers with a CPU & Memory etc. Prone to various component problems.
But.... the biggest & most likely problem is that the DC voltages are not stable
Caused by Leaky or Bulging Electrolytic Capacitors
Do you have access to a Soldering Iron?
Do you Have Access to an Electronic Components shop?
If you are not a Tech Type....
Take it to a service tech & ask to check Electrolytic Caps.
Most Tec's these days will Just Do A Board Swap. Costing $$$
If you are a tech type and feel like exploring & fixing the problem.
Disconnect The Power
No Internal 25KV voltages to worry about.
There is a shock hazard on AC side of Switchmode Board.
Electro Caps on AC side can hold 110 / 240v
Check Switchmode internal power supply on DC Side for bad Electrolytic Type Capacitors.
The insulated Tin Cans on the PCB
Bulging or leaky Electrolytic Caps cause many failures in modern digital TV's
Good Luck
Switched mode power supplyHow to Replace an Electrolytic Capacitor
You need to align the optics mechanically. If you changed the dlp chip and its not centered then the chip is not shimmed properly or the reflection mirror behind the lens needs adjustment. You should get a service manual for that chassis and follow the directions. there may be an electronic method but I am not aware of one.
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.
new lamp may have gone bad. was this the recommended lamp for the unit. Most Mitsubishi units must have the correct manufacturer recommended lamp installed.
The correct part# for this unit is 915B403001
You may find that lamp at the following web site:

Hello, contact Mitsubishi, they are sending out the chip at no charge to repair the problem, but they do not include the labor. if you are handy, there is a video on how to do it, otherwise when you receive the part contact a repairman. If they know what their doing, they should be able to do it there for around $100-$135.....tks

I would think so. BE SURE TO UNPLUG THE TV FROM ANY POWER SOURCE.
you don't say why you want to replace it. You are aware that there are all kinds of safety circuits throughout the unit that could cause it to shut down or not come on! Also don't overlook the MOST OBVIOUS & easiest repair of defective lamp causing it not to come on(you just need to take out 1 screw from the lamp cover, loosen the screw holding lamp in place & pull it out to check it...SIMPLE). Do you have any symptoms such as flashing/blinking light on the front?
Just trying to help you avoid any time & costs chasing ghosts.

Not sure how long you have had this unit. If it is still under warranty your first call should be to the dealer who sold the unit. It may be part of a bad batch. The dealer should take responsibility for replacing the unit or contacting the manufacturer/distributor. Don't let them tell you it's not their problem. They sold you the item your contract is with them. They bought it from the distributor so they deal with them and the distributor deals with the manufacturer so they deal with them.
Are you maintaining the unit correctly? The filters need to be cleaned regularly, especially in a home environment where a lot of dust can clog the vents causing the unit to overheat.
Plenty of airflow is needed to keep the bulb cool so this is vital.
Cheap bulbs will not last as long as original parts but they should still have a 'rated hours value' under normal use.
Resolution is 1080P (1920x1080). It is 3D ready, and has very good reviews from owners regarding picture quality and overall value. One limitation you will encounter, is that it is more difficult to see the screen from the side, than it is with LCD or plasma. Also, due to lamp warmup times, it takes longer for the TV to turn on. However, you will save a lot of money by purchasing a DLP versus LCD/LED/plasma.
check hdmi cables are plugged in correctly if using rgb cabling make sure the yellow is in the yellow and the green blue and white are also in there respective sockets
2 possibilities. First, the bulb which allows you to view your picture could be burned out. If that is the case, your tv will turn on and you will hear audio but no picture. $85 for a new warranted bulb from Shopjimmy.com. Second possibility. If your TV is on with no picture or sound, you probably have a light engine problem.$325. I don't think it's your light engine. Just don't have enough information. Check the first possibility first. The bulb takes less than 5 minutes to replace. Don't buy just the bulb, buy it with the housing. It doesn't cost more, it costs less and saves a ton of aggravation. Don't touch the bulb with your fingers, use latex gloves when working on electronics.
i had the same lines on my 65' mitsubishi tv after replacing the DLP chip. after going back over everything i realized that the casinf that holds the chip in was not in the lock position. i took the chip out and replaced it then turned the little locking mechanism to the locked position. now my screen is perfect. hope this helps.
Its a display chip in the Optical lens unit and yes it is soldered in and tricky to replace correctly--seen several people try this and have real problems---light engine needs to be replaced to really correct this.
