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 supply
How to Replace an Electrolytic Capacitor
SOURCE: mitsubishi wd-62825 dlp
The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.
Bill

hi guys, seems to me you have a problem on you power supply board, replaced capacitor 16 volts 3300uf. 2 pcs and one 1000uf 16volts setting beside on two capacitor

optical block assembly going bad. repair is pretty costly. try vacuming out the fans. DO NOT USE CANNED AIR!!!! you will blow all the crud into the optical block.
SOURCE: Screen is blue with lighter blue lined flashing
defective DM assembly
Testimonial: "Yeah, we figured this was the problem - a friend has had the same experience. Thank you."

The tv projection lamp have problems,it shorting out some how.That why,u have a dim picture.Tries websites like Partstore.com,Ebay.com to buy a new projection lamp for the replacement.New tv,call mitsubishi for a warrenty repair.
