I have a Toshiba 1410 that won't turn on. No noise, no screen light. On mains power the "mains" led is green, but the battery is yellow. Yellow flashes briefly when "on" button is pressed. When battery is removed, still wont go. Should it?
I thought that perhaps the battery needs to be in, and if this is faulty then it may drag the power supply voltage down as well?

Re: Toshiba 1410. Won't turn on
Sounds like a dead battery, You need to try it with an alternative battery, most laptops won't aeven switch of if the battery is damaged, also try ro pull out the motherboard and find for dry joints. i.e. any lose transistor or capacito and try to re-solder it, the put the laptop back together,

Excepting the obvious (you have power from plug CHECKED / you'd be surprised)
MANUALLY try power button / to be sure remote isn't faulty.
There should be some kind of indicator led that set has power.
IF NO lights/ indicator good chance the Power Supply has suffered .. maybe replacing
IF lights but still wont start
Likely the "main" board is bad. (other boards or panel can also be an issue)
. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?
Toshiba? Suspect that if it uses a Lamp for brightness (a model number would help) it may have failed----customer replaceable and if remove look to see it is not shattered inside--2 year, 2000 hour life is normal.
hi welcome to fixya
i want to clarify first the problem sir so as of now the problem with your tv won't power on then you are using again the old main board is that right ? when you use the new replacement main board the tv is functioning will the only problem is that the HDMI / DVI inputs doesn't work. and now you encountered power supply problem like won't start up or something that cut the supply in which the stand by indicator is turn off so as my idea it has a problem with the old board. but before you come up with the board making sure all the connectors coming from the power supply is properly connected to the main board as will as flexible and lvds cable for the T-con board is properly inserted.just let me know if is that what you are asking for so i can give you additional solution thanks for consulting the fixya.
