54" TV HD MITSUBISHI TRN BY IT SELF...HELP

Sounds like a fuse, it will turn on but once it heats up in a matter of seconds then opens up or turns off. Sounds like you need a tech either way, if the tv is worth it.

Since this is an older first generation (1999) HD TV it may not be compatible with newer HDTV receivers because the standards back then were different - Make sure the HD cable box is plugged into the HD component inputs on the back of the TV (not the DVD inputs) and that the menu setting on the TV is set to DTV (not RGB) video. This TV will only accept 480i and 480p signals on the DVD input. Also the HDTV input will only accept 480i,480p and 1080i (it will not work with a 720p signal,make sure your cable box is not set to that mode)

dc6piece,

This unit does not have a HD tuner so you would need a separate box. See Best Buy. They can help you.

Thanks for using FixYa and for the great rating.

It's not the bulb. Google Mitsubishi WD-73737 blink codes. The blinking light is a self diagnostic tool and each blink code represents a certain problem.

I don't think it is with the tv. You got a high end tv there and it is ready to get hd pictures from any other source. Although your tv is ready for HD, it doesn't necessarily means that that you will get all pictures in HD. It will still depend on devices broadcasting to your TV. If the signal is not HD, definitely the final picture on your TV will not be in HD quality.

yeah your tunner on the box needs to replace or get a new converter box that will fix your problem.good luck.

Need more infomation of the syptom and check weather the convergance IC's are working properly?

Ur power ic inverter board is dead.
U need a new one.

Check your manual, I have the same set and you need a
WD 5000 HD upgrade panel, I believe.
This TV is HD upgradeable, it is NOT HD ready, like you have
been told by other responder......

In order for you to receive HD broadcasting you must have a HD-TV, otherwise you wont get the picture in HD. Also I should point out that you need to make sure that the signal itself is being broadcast in HD.
