My toshiba TP48E60 model projection tv won' turn on, power light just blinks


Blinking of power LED are fault indications. Count the number of blinks occur at one time switch on. For this number, you can get an idea about the faulty section circuit inside it. It will make troubleshooting much narrower. If you wish to get more details about the blinking codes, check this link. Pull up older posts there.

65" mitsubishi rear projection tv won't turn


IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

Replace the 2 bulbs. Unit powered up correctly and turned on like normal. Then Lamp1 and Lamp 2 indicator lights blinked (Indicating Start UP). After some period of time, it switched to Red 6 times blink...


1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.
i have nothing on 6 ligths go ahead reconect and check for proper count. hope this information helps.
Best of Luck.

Ray.

Tv works fine,cut it off and it will not come back on . Red light blinks 6 times, then repeats itself.


this is an indication of a overcurrent/ overvoltage error....meaning short in a voltage supply. I have seen this problem in the shop with this set. IN MY CASE it was shorted convergence chips. but it could also be any of the low voltage supplies 5,10 15,-15 lines

Stop working just red light blinking and when I turn off and turn on working just for 2 seconds then again red light blinking


Plug out the disc, and all cables connected to your console after 2 to 3 minutes see if it will run, if this does not fix the problem try to connect to a different outlet, maybe the power supply of your console is damage and needs repair.
