Mitsubishi WD-52725 52". Rear Projection HDTV Logo
Posted on Sep 11, 2017

My tv keeps turning off while we are watching it.

We can be watching a program or a bluray and it won't matter. somtimes it stays on all night and other times it will turn off 4 or 5 times during a movie. I just wait until the flashing green light goes out and turn it back on with the remote.

I have purchased a new, very good, power surger to prevent power issues. It is still going it. Help please.

SOURCE: 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.

1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067002 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). 5. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 6. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 7.

Good Day;

Cause #1 1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 7. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8.

See Service Tip VS-78A 9. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). Good Luck, big IRISH.

The tv works with the antenna and the ski but turned it self off after about an hour when I watched my bluray player and the red light came on. After a couple of minutes I was able to turn back on but...

Go into the setup of your Bluray player and in Video setup reduce the resolution to 720p from the default setting of 1080p.
Some Bluray players have a button on the remote labeled HDMI. Every time you press this button the output resolution will change from 480p / 576p / 720p /1080i /1080p. Try one of the lower resolution that way it will strain your TV's graphic processor a little less.
