Question about Mitsubishi The Big Easy TV
You will have to search for a TV repair shop, and see if they have another 45" Mitsubishi TV of the same model, or close. You may be able to get a replacement screen from salvage. As for the vertical hold, in some cases you may believe the vertical IC is at fault (we will come back to this), may be not. The first suspicion is in the signal board. The signal board is the board with all the RCA jacks and RF connections. Pull this board out and replace Capacitor (location C2V29) this is a 16 volt 22Mf capacitor. Also replace C2P05 which is a 16 volt 100 Mf cap. This will correct your vertical problem. If you can find an ESR meter, I would certainly check all the capacitors in the signal board. You will find several weak capacitors to replace. The two already mentioned are extremely weak or bad. As for the other board (power supply) you may have to resolder the pins on the vertical IC. It will be located on the corner of the board. I do not remember the location. It is mounted on a heat sink, the vertical IC will have a number such as LA78XX. (LA7838, not sure). Resolder the pins on this IC and check the capacitors in and near this IC. I have not received much problems with this power supply. As always, inspect both boards for bad solder grounds and resolder as necessary! Thanks for asking and show all hands of support!
