kp57ws50_57_in_rear_projection_hd_228277.jpg Problem with Sony KP-57WS520 57 in. Rear Projection

This model is really prone to one problem in particular--screen even briefly comes up bright red, green or blue and set shuts down.

15 seconds from turn on front power light should blink as set checks several things internally---if something wrong it does not let picture show.

Usually after shut down or failure power light will blink a sequence of blinks but not always depending on problem.

Did you see the screen at all go red, green, or blue before?

the more you tell me the better I can help

I have a mitsubishi ws55111 rear projection tv i was watching tv last night and the tv screen showed a redish color then shut off, when i went to turn it back on the green lite comes on for 2 sec then...


2, THEN 2 IS MOST COMMON ERROR CODE ON THESE SETS.

What it means is short protection.

95% chance that one or both of the two pico fuses that protect the convergence circuit are bad.

As far as I can tell there is no WS-55111---double check model number.

I have photos of the fuses, I have start to finish instructions for the repair along with everything you would need if you do it yourself===

I have helped over 30 people here fix this kind of problem with my instructions.

Get the correct model number off the back of the set and I will help.

As I do this here for FREE, rate this solution.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Alarm light on and u051 error mx310


Hi

You’ll need to reset your printer to clear the ink counters, after resetting it’ll not display the error code again. Follow this procedure to reset the printer--

1. Power off the printer.
2. Holding the stop/reset button, press and hold power button also. Hold both buttons together for 5 secs.
3. Still holding the power button, release the stop/reset buton, then press the stop/reset button twice.
4. Release power button (the screen should now say 'Service Mode').
5. Wait until the power button lights steady green, then press the stop/reset button three times with a 3 sec space between each press. On the 3rd press the indicator should turn steady orange.
6. Press the power button once, (the orange light should go off).
7. Open the printer and remove both cartridges. Wait for 10 seconds. Replace the cartridges and close printer. Wait for 30 seconds.
8. Press the power button, and wait until printer has shut down.
9. Press power button to power up. The printer will feed one piece of paper, then ask you to set the language.
10. The page counter is now reset.

Please rate the solution & revert for further assistance.

Thanks

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS or something), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

No picture no sound


Hi,

Probably, the selftest fails while turning on. If this is the case, press input&menu buttons at the same time for 5 seconds, then the green led will start to blink. Let me know how many times the led blinks.
