Mitsubishi WS-55511 55" Rear Projection Television - Answered Questions & Fixed issues

Try this and let me know what you find:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

if this has helped you rate this solution as I do this here for free.

i have encounter many of these issues with TVs going bad after a power outage which i something that can be complex. Actually almost all the TVs go through this issue sometimes in their life time. What happens is that TVs have a circuit that controls the on/off phase; the circuit has resistors, diodes and capacitors to do the job. When there is a power surge, which is what happens when the power come back on, a diode, resistor or capacitor goes bad. Capacitors are the main ones that fail under a power surge/outage because they have a set of value assigned to them. The worst that can happens also is that a power transistor can go bad. The unit controls or regulate the power going in to the set. So, if your TV does not turn on, turns but goes dean right after, or has the standby light flickering; you would need to have it check by a technician. On the other hand, you might want to check if its not just a reprogramming that the set needs.

Those 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://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Contact your local utility and file a damage claim.

Capacitors bad in DM

all the cables are marked from the manufacturer & they correspond to matching letters on the prnited circuit board.

Bad convergence IC you need to replace them.

U out of luck,not worth to replaced the screen,the screen it same as the new tv.The tv compannies sell out tv screen as a new tv.The tv 95% worth is in the screen.

In the advanced menu from the main you should be able to navigate to the lock input, when you try to unlock the input it will ask for the code. Just press the QV + 9 and this will unlock the input. Then you can either create one or just leave it unlocked.
I hope that this helps you with this issue.
Thanks for usning Fixya.

system restore is usually a software function (although some devices have the ability to do a system restore from a button somewhere on the device - check / download your user manual for specific details. As for replacing system restore, in short, you cannot. System restore takes an item back to factory state and even if you could you would not want to replace this.

Check its bulb. Might need replacement. If you wish to get instructions about how to replace the bulb, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts, either by entering the brand name to your device in the search box of the display window, or view it in Mosaic / Flipcard / Timeslide option.

Check either http://ebay.com or http://alibba.com.

Check the Mitsubishi TV error codes using the instructions on www.TvRepairKits.com . Look on the tips page. If its a steady blink its likely the blinking light of death issue. If its a 2-2 pattern its likely a convergenec failure. Both are failry easy DIY tv fixes.

Do you have any lights on on the front of the TV? anything flashing? Or is it just dead?

The dm power board is the small board shown in the illustration below it has the 7 capacitors on it and its located inside the metal box on the far left side of the TV when looking in the rear cover. The metal box stands up vertically

If its the model listed above here does the green power light come on at all and then a few seconds later go off?

Its the middle board as seen from front or rear, need help let me know as I have fixed a lot of these sets.SD TECH
