Hey guys, First post here. I have had my wd-73640 for about 2 years with no issues. Recently it shut down and gave a error code 61. The lamp had 10,500 hours on it. A TV repair guy said to replace lamp and lamp ballast. I've done that but set still won't turn on. Any ideas what to try next?

Did you replace the entire lamp cartridge, or just the lamp?

The whole lamp cartridge. I ended up calling mitsubishi and they are saying the whole light engine needs replaced. So unless anyone has any good ideas guess I'll be looking for a new tv.

I apreciate the links but I don't want to spend that much fixing the tv when I can spend that money towards a new tv. I'm having the tv looked at tomorrow to confirm or deny it's the light engine.

Did you check these jumpers after installing the ballast?

No I didn't. Didn't see post until after I dropped tv off at repair shop. I'll hear back in a day or so what's wrong for sure.

Looks like my problem is the color wheel. Spins for less than a second and stops. Just for a feeler how much could I sell tv for? Will have new lamp, lamp ballast, and color wheel.

Hoping someone out there can assist.

Have had my WD-73640 for about 3.5 years not, without issue. A few days ago I turned it on and immediately received an error code 48. Four red light flashes followed by eight yellow/orange light flashes, then repeats indefinitely until the power is pulled.

I've done some Google'ing, but haven't really been able to find a definitive list of what each of the Mitsubishi error codes mean in order to identify what has actually failed. Have come across a few sites that say an error 48 is for the the main board, but also a mention or two that it is an error for the PSU (power supply unit) board. Both are relatively inexpensive to purchase, but of course I'd like to ensure I'm replacing the correct failed board rather than just throwing parts/money at it.

Anyone have any insight or thoughts? Thanks in advance.

According to the repair manual error 48 means:
48 PON-SHORT 3.3V or 5V switched supply short
Most Likely Cause: PWB-MAIN Failure

So, PWB-MAIN would be this part correct?
