Question about Zenith H36F46DT 36" TV
We have tried to brighten the picture - but it does not lighten up - some shows we can not watch if the back ground is dark.
Hi This could be one of three possibilities, one the High Voltage Screen Adjustment is off, Two the Picture Tube is Weak, or Three there is a problem with the Video Drive Amp/Amps, these are things that should be checked or adjusted by a qualified technician, especially the High Voltage Screen Adjustment, hope this helps.
