We have a Toshiba Model 37LX96 LCD/DVD Combo Can't turn on, after a recent power outage There is power going to the unit, but it will not turn on using the remote or using the "power"...


Common problem with the main board. Only happens after losing main power, not just turning the TV off.
I found that blowing hot air with a heat gun down the vents above the DVD player (don't melt the plastic housing) will warm the main board up enough to get the TV powered up again.
You'll be good to go until the next power outage then back to the heat gun.
Also the spec sheet indicates max humidity at 80% so keep the TV in a space with lower humidity.
The Toshiba 37LX96 is a quality TV, not a throw away if you can keep it running.

How do i change the lock code on my mitsubishi md-60735( 60'' ) tv? also please, why can only turn on and off my tv with only the remote? please help.


The only way to reset on a lock code on a Mitsubishi TV is going to be reseting the unit. I believe this unit is reset by holding down the power button for 10 seconds while the unit is turned on. As for the remote being the only way to turn the TV on, does the button on the front of the unit stick, or seem 'smushy' when you press it?

HI:
This is a plasma unit and philips plasma's are nortorious for bad power supplys, your problem may very well be the power suppy in the television, it is possible you blew a low B+ fuse on the power supply. There is also a issue with the Y-sustain board failing in this model, If you open the back and looking at the unit from the rear the y board is on the left side of the unit and the PS is in the center. disconnect the Y-sustain power plug from the power supply and turn on the unit if the unit stays on with no red light then the y board is bad. it does the same then replace the Power Supply.

I turn on my TV and the power button just flashes. There is a sound of the TV turning on and off also. This goes on for about a minute before the TV finally turns off for good. WHY?

Looking for SK-26H520S Power Supply Unit


I had a similar problem where the TV would turn on then shutoff when bumped or over time. The clue was a "tick" sound when it shutoff. Unplugging and reconnecting the power cord go it going again for a few minutes anyway.

I took the unit apart and found the solder connection on the power supply unit was cracked where the main transformer attaches. The solder connection joins the PC board. I suspect the weight causes the joint to stress crack. This is easy to fix by removing the power supply and touching up the solder connections around the transformer. I'd check this first as it is very difficult to locate power supplies and other parts.
