TDP-S8 Power supply led not lighting up. Unit not working

hi,
check the mains chord, also check the power in the wall socket to which the projector is connected. if all these ok then,may be its power supply side have some problem. its an smps power supply. just check its input fuse on the smps. if it fond faulty the do not replace it suddenly. check is there is any thing faulty on the smps board. because the fuse will blow off only if there is any problem in smps. check it first before inserting fuse.
ok

you need to replace the power supply. the caps have a tendancy to dry up in toshibas.

no leds? bad power supply. leds but no fans? bad button panel or main board. led and fans but no light? colorwheel or ballast.

Check the color wheel if it is not turning when you hit the power button (light should flash) you have 1 or 2 loose caps on the bottom of the main board behind the audio input try to resolder them with low heat iron these are smt caps and very hard work on if you have not worked on this kind of job take it to a expert
good luck! ps make sure you glue them down
if you do get them to work to prevent a reocurance.
OR you have a power supply issue which
should be a swolen 3300 mf 10 volt cap
in the main power supply.

My TDP-T9 had the same symptoms. A 3300uF 10V electrolytic cap in the power supply (Liteon) unit was domed up, so I replaced it with a high-spec 2200uF 16V cap costing three dollars. The re-flow solder on the board was damn hard to melt though, needed 400°C setting on the soldering iron.

you have a bad cap in the power supply!!

I had the same. Try to press the "input" and "menue" buttons and plug in the power cable. No control light should be active after that. Press the "power" button and it should work.

probably power supply or ballast (starts the lamp)

either would be $600.00 or so to repair, probably costs more than the projector is worth.

The main problem is the power supply. In detail, the output capacitor of the power supply causes the problem. I guess, Toshiba or Lite ON didn't consider the aging effect of the output capacitor. You should replace the output capacitor to fix the problem. (In some sites, they recommend to replace the power supply, but don't do that. The new power supply costs over $200 and the capacitor will be less than 50cents.) If you disassemble TDP-S8, in the power supply, you can find the electrolytic capacitor 3300uF/10V. You should replace this with any electrolytic capacitor with the range of 2000uF~4000uF/10~16V. You can download the service manual from some websites (I've paid $5 for this) then you can disassemble the projector. Of course, you need to do soldering to replace the capacitor. I've fixed this problem yesterday and it took about 4 hours for me. Good Luck~~!!
