After tv is on for awhile it starts buzzing

The Polaroid FLM-323B does not have a QAM (clear digital cable) tuner. It only has NTSC (analog) and ATSC (digital OTA) tuners. Retrevo has the manuals for the Polaroid FLM-323B here: http://www.retrevo.com/support/Polaroid-FLM-323B-TVs-manual/id/279ag018/t/2/ . You will need to enter a code to access the PDFs.

I wish that I had better news for you.You will need a set-top box if you want to watch digital cable.

blue screen comes when there is no signal. look for rf in cable or try it with dvd player or any other RF or video source

mine did that then it would not turn on after a couple of weeks, the blue light came on but no picture. I changed 2 caps and fixed everything. check out this website, http://plasmalcdtvrepair.rankwell.net/2009/03/lcd-tv-problem-polaroid-model-flm-3732.html

I may be able to help with your Universal remote and your Polaroid FLM-323B HDTV.

You can find some Polaroid HDTV Remote Codes here.

I hope that helps.

panel defective.caps only repair a power supply issue where the tv wont come on at all.
lines are 90% panel and 10% control pcb
connected to the panel.most control pcb are not
sold separate from the panel.

there might be some loose contact inside the board
check those chips for any fire r anything 
this could happen due to heat also

When we turn our TV the humming and buzzing begins! We cn mute it and it goes away and then it when we turn the sound back on the sound is back! How can we fix this?

many things cause black pix ,

start with loose plug on power supply ..

signal bad.

It is important to remember that you will not get digital audio out unless your source into the unit is digital, such as digital tuner or Hi Def cable or sattelite.
