My 52" mitsubishi Model LT-52151 has sound no picture

Wow. There could be several causes for that. This model does have some history of main board failures after a few years of use, but let's hope it's simpler than that.

We'll start by assuming that the symptom shows up on a cable or satellite feed. Have you also tried playing a DVD? If so and you get a picture, the problem is not with the TV -- it's with your cable feed, the cable box, or the connections between the box and your TV.

Check the cable equipment first. I'm guessing that other sets in your house do get a picture, and that therefore the cable feed is good. If that's true, check the box connected to the Mitsubishi. To do so, pull its power plug out of the wall and wait a couple of minutes, then plug it back in. (It will take a minute or two to restart, and the program guide will be empty for a couple of minutes more.)

If that doesn't bring back the picture, the problem is either the wiring to the TV or something inside the set. We'll start with the wiring.

Assuming you're using HDMI cables (single wire with one rectangular plug at either end), try unplugging and replugging them at both ends. These connections sometimes become loose, and doing this will restore the connection. If that works, go buy new HDMI cables -- yours may be getting tired and should be replaced.

Some cable companies routinely use the old, less efficient component cables (5 wires, with 5 round plugs at each end) to hook up TVs. If you have them, just make sure they aren't loose in their sockets.

If that does not correct the problem the chances are your set has an internal failure, either on the main circuit board or in the display section. Try disconnecting the power to the TV for a minute (pull the plug). Sometimes this resets the main board on this model and it begins to work again.

Otherwise you'll need professional service, which can be expensive. It's possible the backlight on the display is gone, which is not that pricey an item. But circuit boards can be expensive, and labor costs mount up quick. So don't commit to getting the TV repaired until you find out how much it will cost, even if you have to pay to get an estimate. Your set is around 5 to 6 years old, and given the price of a new TV, you may find out that it doesn't make sense to fix the old one.

Good luck.

Hello. I was in a live session with you earlier and it seems like you accidentally closed the window. Does the tv tv click on momentarily before it shuts off and starts blinking?

Mitsubishi 52144 won't power on with blue flashing led

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Shaky Picture only during Advertisement or... Mitsubishi SC 27403

If you have cable then put the cable wire directly in the TV, bypassing the cable box. If the pix is Ok it proves that the problem is the cable box. If the problem is still there then it proves the the TV needs parts inside.
