Most likely you are looking at conversion chip problem. The replacement price on these can varry widely. It may be cheeper to look into purchasing a flat panel lcd or plasma tv.

My mitsubishi medallion hd 1080 doesn't show content from component cable


Some of the older Mitsubishi with HD 1080 have only one component input for HD---it is marked on rear as DTV----also a model number may allow me to give another suggestion--Some of these sets (ws, wt, vs models) will on occasion lock out or disable the input/s.

Depending on model number most also have 3 hidden menus---one is the option menu----it allows with the Mitsubishi remote via a 4 digit number (by model number) to enter there and do a hard reset of the set----sets every setting back to factory original---seen it "cure" all kinds of odd problems from missing rear inputs, no sound, odd video issues---you name it.

Get me the model number and I will see if can find the code for yours--you can also try hooking first direct a 1080 blue ray or Dvd if you want to see if the input is active or not first.

I have a Mitsubishi HD 1080 55


Your unit has some sort of Thermal problem either with the PSU fault, or a thermal problem elsewhere that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. T

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Why can't I receive in HD? i have the hd1080


Your set will only convert to 480p. There is no way a conventional crt based tv will get 1080p. The proper connections will be using the RGB component inputs on the jack panel ( red,grn,blue ) then the white and red for audio. The picture will be a lot better than standard cable but not as good as HD. ( 720p )

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

If the Blue lines are blurs or shadows, then your Convergence IC's are going or gone bad.
I have the same TV - it will be 4yrs. old in Dec. Mine started with Blue lines & shadows, then Red, Blue, Green Shadows. This is caused from over heating. The Convergence IC's have to be replaced.
I have had 3 TV Repair shops all quote me a price from $350. to $400. to repair. They all said 4 years is the usual life time for these IC's.
Replace the STK932-110amps with STK394-250-E or STK392-150 for greater reliability.
Use only Original Replacement Parts, there are some cheaper but won't last and can't take the heat.
If you are a "do-it-yourselfer" here is a link with the directions and pics.

The format of what you are watching plays a major part in whether all of the screen is used. If the program is 4:3 the screen will remain pretty much square. 16: 9 would be the most desirable for filling all the area. Go ahead and acquire a manual, they're not much...accordianman
