Mitsubishi Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| MITSUBISHI | TC-2098 | Tip | To quickly conclude if the defect is in the power supply or in the rest of the television, use external 115v/12v/45v power supplys, without using the television's power cable, place the power supplys on the diodes' cathodes: d950/d951/d952, if everything works just go back to the power supply and fix it. | ||
