To localize issue better try plugging your xbox into input for your ps3 and see what happens. You may have a bad input. Happens.

I would reset your picture settings and verify the TV box(cable SAt, etc) is sending the right formatted image. Make sure its not letterbox or 'zoom' for instance.

Where is the reset button on a 65 CD Mitsubishi HDMI TV

Did you also replace the power capacitors on the power board. Usually the DM board and Power board caps together will cause the steady blinking led the DM caps alone only rarely cause the steady blinking led usually its a combination of both boards capoacitors failing.

Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

Once you take the shield assembly off, you will see a board, I believe it is the DM Board board. There are four Capacitors grouped together probably rated at 35v 1000 mfd, 105 degree. They should be replaced with 35v 680mfd,105 degree Capacitors. Now once that is done, there is another board under that one. This is the Format Board. It also has 4 Capacitors that should also be replaced. They are the same value as the first Board and should be replaced with the same 35v 680mfd, 105 degree Capacitors.
Please note the Flex connectors at the bottom of the DM and Format Boards. They may not be available from Mitsubishi any more so be gentle with them and make sure the are installed properly when reinstalling the Boards back into the chassis. There is one other Board you should look at. The Power Supply Board is the board on the back of the chassis and also has a number of Capacitors that fail. Most all of the Capacitors that fail through out this chassis will have bulging tops. So any you see bulging, you should replace whether they are on the DM, Format , or Power Supply.

I have the same problem...

On your TV set remote are you selecting the proper input; for example when you have different devices connected to the back of your tv set, dvd player, vcr, cable box etc; you have to tell the tv which device you want to use by selecting the right one on your tv remove input selection. Hope this was any help.

Look at it really carefully where the bulb plugs into the lame the connector is not sitting firmly on it reconnect it and make sure it's firmly connected to the plug.

sounds like a possible issue with the Optical light engine itself.

Most common reason is the socket is damaged--have to replace board which also controls this function...........

The DM boards for that chassis are almost impossible to find if they are still good. Have you tried replacing the caps on the DM board that you have? Thats usually whats wrong are bad caps.

Yes the capacvitors on the power board can cause the red lamp light and a 34 error code. The V26 Power repair kit from www.tvrepairworld.com will usually solve that issue. The kit contains the upgraded caps and the CD with instructions for the repair.
