USB cable. I think you would need male to female on both ends.

I had this same problem, make sure that the TV is not plugged into a power strip. Also check to see that the sleep timer is not turned on.
Good luck.

abal1974,

I hate to be the bearer of bad news but this unit has several serious problems. The electrolytic capacitors on the DM and power supply boards dry out and go bad. Mitsubishi no longer supports this unit. The good news is that the following site has a repair kit which may solve your problem http://www.tvrepairworld.com/mitsubishi_repair_kits . I have a tip at http://www.fixya.com/support/r4425498-basic_standard_tv_troubleshooting which should be helpful to troubleshoot the unit.

Thanks for using FixYa and for the great rating. Please consider a testimonial.

Jackpot. Sounds like your red color gun has died.

look for dry-joints on the guns and convergence boards

Hi the select input source is called Device Selection Menu or Device selection. It is often indicated as DEVICE in the Mitsubishi remote.

Here the service manual.

Here is the manual.

It appears to be a common problem with these units. Looking at the chats in different forum on the internet including fixya.com, this problem is reported as early as 2 years ago by some users.

The solution might involve going to a technician to fix it. But if you have the original remote unit and the manuals then first try to do a hard reset of the TV to the default factory settings. You will loose all the programmed channel selections etc.

Good Luck.

If it is definately the green tube, then NO it is not worth repairing.

generally this means a bad digital module.. as a techinican the first thing that we would check are what is know as standby voltages. if they were there we would replace digital module.! question. Does it blink for more than 70 seconds. This unit comes with a lockout feature. to unlock press and hold menu down for 10 seconds on front panel.

There is a hard reset you can try on this set--it is done with the Mitsubishi remote that came with the set.

Confirm actual model number and I will tell you how to try it. The set will shut off after the reset(not the reset button some of these sets have on the front) and come back on channel 3 in the air band--any labels for inputs will be replaced by original input numbers etc.

No guarantee this will fix your problem but it will return the set to the condition it was when new in the box.

Let me know if you want to try this.

My mitsubishi little green timer light will not quite flashing and the tv will not come on.

it is tight, and some what glued in place just pull firmly and straight up. it will come out ok.

Hi,
Check this link for guidance with pictures about DM board removal.
Thank you.

Get you a little solder and a cheap soldering iron and try soldering the vertical output ic which is mounted on a heatsink on the circuit board. Be careful when disconnecting plug connectors and I suggest marking them as you disconnect them. Also resolder the convergence i.c.s which are mounted on the largest heatsink on the board. Vert. i.c. has about 9 - 11 pins and convergence have about 25 ea. Start by carefully undoing all wire ties, remove the few screws that hold in the board then slide it back towards you to access bottom(solder side). For the most part, any component that is mounted to a heatsink gets hot and cools down when set is off causing cold solder joints. So any part mounted to a heatsink is suspect. This repairs a high percentage of sets like yours. Good luck, Russmann.

Did you ever resolve this problem and if you did, what was the fix? My same tv just got out of warranty and I have the same problem. Thanks.

replace the DM or have someone repair the DM. The capacitors are bad and someone who knows how to repair circuit boards can replace them

Check your set for coolant leakage. It is very prevalent on Mits HDreadys.

If your 4 layer Signal board - beneath the blue gun - has coolant on it, you'll have problems finding a replacement. If it's the boards under the other 2 guns, they can always be repaired as they are single layer.

A drip shed should be installed to keep the coolant off your boards.
