Question about Mitsubishi VS-55705 55" Rear Projection Television

2 Answers

Power Problem 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?

Re: Power Problem

A few things come to mind, but if you have no solid state experience with TV repairs, you really should let a trained tech do this repair. 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 cold solder connection.. Remeber stay safe as this is no place to be experimenting with. Good Luck Ps please dont forget to rate this thread.

Is your girlfriend's television higher resolution? If so, the ps3 may be configured to output a signal that is too high for your mitsubishi. With the ps3 off, insert either the component or the rgb to the back. The turn on the main ps3 power switch so that the red led turns on. then hold down the 'power on' button. it will beep initially, then beep after about 3 seconds. This simply resets the output to the connected cable in a normal resolution.

If this fails go to settings>video output> and play around with the settings there. note you may have to do this on ur girlfriends tv to be able to see what you're doing...

KDF-46E2000 turns off then back on by its self

* Most common would be a couple of capacitors in the power supply that are not letting the proper voltage to the lamp.
* The lamp itself is not working properly.

All modern Sony television systems have a set of fault codes that causethe LCD by the start button to flash a set number of times to indicatea range of problems. You do not state a model number, but as Iunderstand it, the codes are universal.

You can find a full list of the codes at this web address.
