Haier Model HLH326BB LCD TV. When I turn it on, the screen comes on for a split second and then goes black, but the audio is fine??


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

Screen went black/blank can hear sound no picture, cannot change source or access menu LN-S4692D


Your inverter circuits and/or power board need servicing.....

Either three fault scenarios are happening:

1. the inverter circuits are not producing AC ripple too the CCFL lamps that illuminate the LCD glass panel.

2. the power supply board is not feeding 24vdc - 12vdc sustain voltage too the inverter circuits. Meaning, no dc high voltage output from the power board.

3. The timing control circuit (LCD Board) has shorted switching devices or on-board memory has failed....which causes data/dc loss at the input which results in the inverters canceling load power (lamps). The sync data between inverter and LCD Board are absent. This will result in a 'NO LIGHT' condition on the LCD display.

Number 3 is a rare case, its usually #1 the inverters need servicing.....
