Hey BooBoo198,

One of the most common reasons why this may occur is if your TV has encountered a recent power fluctuation/surge or has detected any kind of unusual feedback. As a safety precaution, many newer TV's will automatically shut themselves down whenever either of these are encountered. Many models will have one or more lights on the front of their case that may blink if this has happened. According to information from the manufacturer, simply pressing the "System Reset" button on the TV should resolve this kind of issue. If the problem persists however, you may wish to try using a different AC line power conditioner/surge protector.

If the TV doesn't turn on at all, this can also be an indicator that the bulb or lamp in the TV has burned out. Please keep in mind however, that it is generally best to double-check with your owner's manual documentation for confirmation of what any steady/blinking light means.

Additionally, Mitsubishi has indicated that if the "Status" light is either steady or flashing red you may need to contact a factory-authorized repair facility for service.

If you have not had any luck working with either Mitsubishi itself or Circuit City, remember that you can always contact a Best Buy™ representative for further assistance. If we don't have a repair tech in your area, Best Buy™ would be glad to locate a factory-authorized third-party service center on your behalf.

You can reach us by calling our toll-free hotline at 888-Best-Buy (888-237-8289), and asking the operator to speak with our in-home TV repair department.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.

It should have MOV (130~150V rating) across the Line and Neutral after the fuse, unless this TV was made to work from 100~240v range. You should check to see if the 5vdc standby is evev working right now, withot it, nothing else will happen. Checkt the DC voltage on the large electrolytic cap (the one with 150~300uF 350~450VDC rating) in the AC primary side, it should be connected to the bridge rectifier, it should have around 160vdc (120v x 1.414) on it.

Does it come and go? I would try reseting the ribbon cables between the LCD panel and the T-CON board first.
The Flexible Printed Circuit BoardS (FPCB) are ultrasonic welded to the LCD TFT panel, they are not SOLDERED on! The connections do get bad due to very delicate nature of how the LCD panels are made. You can also try squeezing the around the top area of the screen where the lines are to see if the lines go away.

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

No sound at all on Mitsubishi LT-52151. Fixed before by unplugging, waiting 30 seconds, plugging back in. Was occurring more and more often to the point of having to do this every time I would turn it on....


Just fixed this on my TV today! (after 2 months of the sound intermittently failing to turn on and failing completely yesterday) Go to Mitsubishi-tv.com. Go to support. Enter your model number. You will be directed to the documentation for your model which will include a zip file for a firmware update and a PDF file with instructions for installing the update. This fixed my sound.

Mitsubishi 65" LCD (1080P, DLP) keeps shutting down until it "warms up". After shutting down the power led flashes yellow for a minute or so, at which time I power it up again. This cycle repeats 1 to 4...


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV may require service.
