Question about Mitsubishi WT-42311 42" Rear Projection Television
The code 2-2 does indicates a short protect fault, which is usually caused by a failure in the convergence section. This is a very common repair in these sets. The typical repair involves replacing the convergence ICs (integrated circuits), and testing/replacing two small pico fuses.
The replacement ICs for your set are part number: STKxxx-xxx and are available from www.encompassparts.com for $19.95 each (needs two). You will also need at least one (likely two) 5 Amp pico fuses. If you wish to repair this yourself, the ICs are located on the large heat sink on the center (Power) PC board. The fuses are also on this board, near the center, location numbers: FXAXX and FXAXX. You would need soldering equipment and very good soldering skills to replace these parts.

If you were to call a local shop to repair this, the labor to replace these is roughly $250-275 (in my area) if the TV were brought in to the shop. Please add a trip charge if repaired in the home.
The fuses must be tested with a multimeter to see if they are bad. They are only $2.50 each, so most people without a meter just change them both. If the repair has any problems, like a solder bridge, you may need a meter to check them after that. A good magnifying glass helps prevent solder bridges (for me, anyway).
Let me know,if needed further assistance.
Hope i helped you.
