I recently got this TV from my brother -who purchased it new back in 2000 - The problem that I'm having is once I've turned it on - finished watching it! and power it off! and won't turn back on unless I unplug it from the wall - and let it sit for 4 hrs - I saw this solution on the internet -and it was called a HARD RESET - once I've done this - and plug it back in - the Green power light flashes twice and then goes steady! After that - It will power up! but - if I turn it off - It's back to the beginning - unplug and wait 4 hrs ?? any idea as to the possible cause or causes? Other then this - they TV is great and has a GREAT picture - It was not used very much - maybe 400 hrs on it? if that.
Please help?

Update- I called out a TV electronics service location that I've used in the past with my Mitsubishi 50" that was covered under extended warranty thru Ken Cranes - and used as a authorized repair facility that I've used in the past and trust. They came out and checked out the tv - apparently one of the CRT's had leaked onto the PB Board. They removed the entire chassis and just called to say it's ready to be delivered and reinstalled.
They had to replace the System Module - and the Power Regulator -Parts were $250 - Labor $150. The repairmen also mentioned that the leaking CRT's are common - and they would ensure that I would not encounter this again after they were done! a shield or something that they place on the bottom to protect the board? Does this all sound on the up and up! or did I just get taken???
Thanks

Well! I'm totally confused - The TV repair place called yesterday to set up a time and date to come out and re-install the entire chassis - So the guy comes out - and installs the chassis - turns the tv on and does the aligment and tuning - (Paperwork) Indicates that the System Module and the Power Regultor have been replaced! Leaves - and not more then 20 minutes later - I power it off - and then try and turn back off! Back to square one! I called the shop back - and they sent the repair guy back out! this time it's two of them - so they pull the TV out - do some testing and think the system board is bad again? how can this be - The removed the entire chassis again and were taking it back to the shop! When asked what the problem was or is? they were not sure - Shows that there is power coming in? but thinks there might be a short! in the System Module?
Could this have been caused when they were connecting the components into the TV? Digital Cable box, VCR/DVD Combo and DVD Recorder ? with possible power on?

Update - Repair placed called and wanted to come out and remove the control panel off the front of the TV - as they were thinking it might/was the cause - However the called back a few hrs later and told me that they didn't need to! as the system board failed! They had it running all day and when they turned it off and tried to turn it back on! the problem appeared! I've got a major concern on this tv and the repairs thus far! $455 so far. This place is an authorized service repair facility for Mitsubishi - However I feel that it's a wasted issue - and I should just buy a new one! I've seen one at Sams Club for $1000.00 Model: R56WH78

This is a post I responded to on fixya. If you read the message from techman, you would see a known fix for the repair, as alot of peeps forget about or do not know about this repair after the board gets leaked on. There is a resistor that changes value in the power supply that goes bad sometime, its R902, a 270k 1/2 watt, A capacitor that goes bad also in the power supply, C920- 10mfd @ 100volts, and R540 off pin 5 of the flyback will open up or have bad or cold solder connection. Good Luck and please ley us know if you find the problem or what the repairman found.

I just called them - and they will be coming out to the house today! Not sure what they found out - I did mentioned to them that I had been searching out on the internet for possible problems mentioned this! They have said that they replaced the System Module and the Power Regulator! and tested everything on the bench - this was after they had installed the chassis - fine tuned it and left! once the tv was turned off! it would not power up or turn back on!!!
I was charged $451.00 for parts and labor - $98 on System Board $59 on the Power Regulator - and the rest being installation and technical support! at which I'm very concerned about now! as they keep saying it's something else causing the problem? What do I do now!
Well your stuck between a rock and a hard place im afraid! let us know if they finally fix it.
Update - Well the repair/service man came out and install the chassis/unit and it's now! working without any further problems - When asked about the findings on this latest occurence and problem! he indicated that it was a resistor -and it was replaced. All the paperwork shows are the names of the parts - not the part numbers? System Module, Power Regulator and now a resistor- in which they did leave behind the package it came in! p/n 267P140020 /descp: IC-STR-F6628-HIC - Could this have been the problem from the very beginning?? I think so!...
Thats not a resistor, its called a regulator IC my freind.
