    Use normal PSU fault finding techniques
    Start with , Any power from secondary of chopper transformer, at the diodes)
    usual PSU voltages are 5v,3.3v 12v (the 12v feeds the CCF tubes power generators)

    If yes the psu ok, If no check for 320v across mains smoothing capacitor
    If 320v ok but no output, check for shorts on the output lines (schottly diodes)

    If the PSU is running and there are any leds glowing on the front
    check to see it the flurecent tubes (on each side) are glowing
    they usually have their own supply generators powered by 12v from PSU

No there are no schematics available online for this model.
You would be most likely best off having it serviced. If you need any further assistance or information let me know.
Thanks,
Nate

Red light mitsubishi wd-52531 what do i do


red light indicates that your tv is getting 5V. supply from power supply. but it does not indicate that microcontroller which is responsible for functioning of tv is working. if you are a technical able person then you can check micro controllers' power supply, its oscillation, its reset voltages, its key matrix, & infrared receiver. so you will be sure where the fault is. or you may call an tv repair expert.

Power light indicators on flashing red as warning that battery is almost depleted of functionality. ascertain that devices with extension cables deriving power from elsewhere are plugged in to reattain power to acheive regular functionality. For example, devices with red light indication as power warning would also flash yellow or green when in full power charge from another source. refer with devices user guide or manual for refering, diagnostics.

My sony grand wega kdf e55a20 power light keeps blinking red. what can the problem be?


Red is an indication signal for power connectivity. Recent devices have two power functionalities. Using the remote control would turn off the display of images to power saver mode. A red power light imiting diode display is indication that requiring display of images is achievable by pressing on the display mode button once more. NOTES; Powering on the device may be achieved with the same function buttons as shutting down the entire Device to least communicate with the power supply circuity from outlet sources. The device is in power off mode ready for repower on with the remote control. Requesting the TV to shut down completely would require to press on the TV button firmly until power cuicuit are disbabled completely. Refer to the TV user guide to ascertain fucntionaility modes usual during operations. Goodluck

When I power on the tv, the light goes to green and then a few seconds later goes to a red flashing light


When a set is powered up, there are internal checks that are performed. The initial green light indicates that power has been applied. The flashing red light indicates that a problem was found that is preventing the set from functioning properly and it has shutdown to prevent further damaeg. If you can supply the model number, I may be able to provide additional details. Also, check to see if the flashing red light has a pattern. Quite often the pattern will indicate what problem was detected.

Thanks,
Dan

KF-WE42 Indicator flashes red.


Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
