Hi


Thanks for using FixYa. Assuming this to be a projection TV, from what you have described it seems to be an issue with the power board of the unit and/or a blown fuse. To check which part has gone bad, you’ll have to open the back of the unit and check for bulged capacitors on the power supply board, also this can happen due to a bad lamp. If there is any light blinking on the front then please post back the no #of blinks and also the complete model any #of the unit so that I can further assist you.




Thanks
Rylee

Did you reset your settings on the PS3 to display in 1080 whatever while you were there? If so, you may have go back over and change the display setting to "automatic" (or automatically detect...I don't remember exactly what it says off the top of my head). There may be an easier fix but I can't test it for you because all of my tv's are HD. For future reference, "automatic" or "automatically detect" is always the best way to go with settings. It avoids situations like this. :^ )

Good luck.

How do I reset big screen tv to 1080 on remote


You don't.
It should automatically switch to 1080 when and only when there is a HD signal present. Otherwise it will be in 480 and you will need to use the format button on the remote to change the picture size. If it does not switch to 1080 and you know for sure you have a true HD signal present, there is a problem with the unit.
Hope this helps,

MITSUBISHI HD 1080 series


most likely the convergence Ics have failed. Check F9a04 and F9A05 pico fuses if they are blown you will need to replace them and the convergence Ics.They are located on the center board they are green and look like resistors without the color band. see the photoa193b32.jpg82b89b8.jpg

Phillips hdtv


if the cable box is sending in 1080 signal the tv will not be able to format to a 480 (you can switch to either/or)
the problem you have is if your not sending 1080 to the tv your not really watching HD but you cant strech the 4:3 (non HD channels) to the 16:9
the only thing you can do is run analog signal and a digital signal then switch between the two sorces for your HD and non HD programs

HD setup, 480 to 1080 not working.


I had this same problem, got my HD installed yesterday w/ Direct TV, have had this TV since '02. The fact that is wasn't working, and Google, led me to your post in search of answers. I even went to a local retailer that sells the Mitsubishi TV's and they were as helpful as if I had gone to a drug store seeking the answer. So, between browsing other posts, and then going to the manual (who'd of thunk) I got my, and your, answer. You need to do the following, nothing magic: 1)Connect the component video output of the Direct TV HD Receiver to the DTV inputs on your TV. The COMP 1/2 inputs are NOT 1080 compatible, only the DTV input. As another poster said, you must use component video cables, not the old red/yellow/white cables. you can lose too much signal quality w/ the old R/Y/W cables and your TV still won't recognize the 1080. 2)Set your receiver to a HD Channel, which are in the 70's. 3)Use the format selection on your remote and select until you get the 1080i Standard (or whatever your preference is) format. 4)Enjoy Bottom line is the COMP inputs are not HD. Page 64 of the manual (at least the one i downloaded from mitsubishi-tv.com) is what gave me the final piece of the picture. Good Luck!

I'm hoping to get some clarification as to whether the below is correct or whether I have been taken for a ride. My LG was picked up by a repair service because it started displaying horizonal lines with the picture hazily in the background. I undertook some research and learned that in most cases of the boards needed replacing and it wasn't a panel issue (usually panel issues are associated with vertical lines). After having my TV for 5 days the repair service advised that it required a new power board and a small repair required on another board. They repaired the small repair and I was going to purchase a new power board however the TV has been returned to me dead. It now doesn't even turn on. The power/channel/indicator lights at the bottom flash on then switch off automatically. After getting consumer affairs involved, I finally received a call from the sub contractor and aside from a number of different excuses given based on my questioning of each explanation, all were contrary to the initial diagnosis discussed with me in early June. I documented the conversation which I summarise as follows: - he contacted numerous times however I never received any voicemail. I asked why - after "numerous phone calls" he didn't send a txt msg to which he replied that he's not allowed to send messages. - he initially alleged that the power board was repaired and video board needed replacing which I was quoted for. I corrected him advising that I was told and quoted for a new power board ($530) and the video board was to be repaired. He then changed his story agreeing with me and alleged that found and apparently quoted me $445 for a generic power board but I declined....Just to clarify, I never received this 2nd quote which is evidenced within the emails and messages I sent after receiving no response over a number of weeks. - he continued to claim that the TV now has panel problems and is now not repairable. - I recited the discussion the owner had with me which was consistent with the information when he provided me with the original quote of $530. He then altered his story replying that "this is a rare case... The owner doesn't know what he's saying". - When I challenged why I was quoted for a power board when he is now claiming there are panel issues, his response was that a new power board was to test if the panel was cracked!! - I replied saying that the TV was delivered to them with horizontal lines and even after testing should've been returned with horizonal lines however is now dead. - his excuse changed again advising that during testing he short circuited the TV and replacing the power board would continue to short circuit the video board..When I again questioned WHY then was i quoted for a new power board (as per the owners conversation with me) he returned back to stating that it was a rare case! - I told him about the screws missing in the back panel to which he commented that "they" wouldn't have put them back in because "they" assumed I would just dispose of the TV. What I find interesting is that this was his understanding whilst I was led to believe the TV was repaired (pending a new power board). It now makes sense as to why the driver who delivered the TV literally dropped it off and ran advising that he didn't know anything. I never received a service report and asked for it again however am yet to see it. Based on this information, can anybody shed light on what they've done to the TV? Prior to them taking the TV the horizontal lines were consistent with had a faint picture in the background and didn't alter at all. They're claiming that they did nothing and the TV - claiming that the reason why the panel doesn't turn on is because it was kept on while they were testing.
