Akai LCT2701TD SMPS Failure

I was recently playing Halo3 on my cousins Akai, when I decided to change the display resolution from 420p to 720p then to 1080i. I'm sure you know, but just in case, yes the T.V. supports it. In fact it changed resolutions no problem, then about fifteen seconds later, it just started beeping and tried to turn off, and then I heard a pop, and the whole system went dead, no standby light blinking, nothing. I'm not a technician but most time when my CRT televisions went bad all I had to do was check the fuse and replace it. This time the fuse was fine so I took a look around and noticed that the caps were blown. Again I'm not a technician, so I took it to my friend who is. I also used a solution I found on here to help my friend know where to test and what to look for. But that solution involved a red blinking standby light, this tv has nothing. I was hoping one of you may be able to send me a schematic for the mlt166a smps, my friend has done alot of testing and replacing of the blown parts, but we can't find the last part that needs replacing. And I don't have 70 dollars for a new smps. Any help would be Greatly appreciated.

Sharp 32 32sb3u

The resolution that the Xbox is pushing out is most likely too much for the TV, and it switches off because it can't physically display the signal.
Try hooking the xbox to another TV (if you have one) and setting the resolution to something in the neighborhood of 420p so that you can see the screen. After you do this, take it back to your TV and switch it slowly up in resolution until it blinks out. When it blinks out, you know that the resolution is too much.

Change it back to the next lowest resolution and play away.

A message is on my screen that says, "Video 5 HDMI is not supported

Whatever you have plugged into HDMI 5 is set to a resolution that exceeds the TVs ability to display. Try setting the source to 720p or 420p

Read the info from the link below to troubleshoot the failure with your LCD. Try not for force the LCD to work because for the time being it might only need the capacitors listed in the link but if the lights is blinking red, then the failure is a bit more complex to repair.

TV set always starts up indicating 420p. How do I get it to 1080?I have Bell expressvu HD

is your cable or sat in HD(720p, 1080i, 1080p) over the air broadcast in the usa is in digital so it should start at the highest res available in your area

next are you using HDMI or composite for your cable or sat going into your tv if not your not going to get higher than 420p because A/V and S-video do NOT support HD

check your cable/sat box is it HD(high def) or SD(standard def) if SD going through cattv/attn in your only going to get 420p

now for changing the resolution its automatic it goes to the highest setting on its own

you can control the resolution through your cable/sat box, blue ray/hddvd player and other HD devices connected to the tv through the options menus of those devices BUT only when connected through

HDMI(supports 720p, 1080i, 1080p)
composite(supports 420p, 420i, 720p)
A/v and S-video(supports 420p)
cat tv/attn in(supports 420p, 720p, 1080i, 1080p) only supports what the tuner will do

My proscan tv is on 420p setting. how do i set it to 1080p?

You do not set the resolution at the TV, the TV will display what video resolution you feed it, I also doubt that the your 19" can do 1080P.
