Service Modes, Error Codes, and Fault Finding 5.1.1 No Display Check each section with following method. If there is a problem, replace or repair that part. If it is not found, go to the next section. Connectors Check all connectors (PSU, Y-SUS, CTRL, Z-SUS). The module may not function normally by a misconnection (can not send signal and/or power). Also misconnection for a long period can cause a specific board to fail. LGE PDP 2K6 5.

If there is a problem, replace the PDP module by a new one. In case of vacuum breakdown, the module makes a shaking noise because of inside gas ventilation. There may be a small crack, which cannot be seen with the naked eye. This noise is different from capacitor noise.
