Question about Samsung HLN4365W 43" Rear Projection HDTV-Ready Television

1 Answer

Red light temp comes on and tv turns off after a while of operating. The lamp was replaced a year ago and the set works fine until it overheats. I suspect one of the two cooling fans are not working properly. There has been a screeching noise from the set for a while which sounds like a dry bearing in a fan. I require to know the procedure to get access to these fans i.e. what parts of the tv enclosure to remove to get at them. I would also like to know the electrical ratings of the fans i.e. their specs. Regards-- Ron and I look forward to your reply

Hey thompsonsrj, basing my answer only what little I have learned about one part of your problem you pointed out the screeching sound... my tv also did this and I discovered through research that it is indicative of the Color Wheel going bad. It is a $100 or so dollar part and can be replaced with a bit of elbow grease. As far as the overheating, possible cooling fan issue, I am unsure if they are related? I hope this helps a little? Thanks, Will

I would suggest it is a ballast problem. You can check supply of 5 volts to ballast's small 5 pin connector (trigger voltage) and about 300V-330V to large 2pin connector. If both voltages present at the start and lamp is working with in another TV - it is bad ballast.

Tv will not turn on


For dark picture I need to ask one question, How long ago you replaced its lamp? one year, two years?

Picture brightness is depends on lamp in LCD rear projection (DLP) TVs and if lamp got weak in generating light, you will see dark picture.

I would recommend to replace lamp and buy Sony original lamp from Sony Accessories Store.

Required lamp part number is as follows..
F93087500 LAMP BLOCK ASSY XL-2400
and price is $200
Good luck.

TV Not turning on , but blue power light is on


look in the back, see if the lamp is actually lit. If it is probably not a tv problem. If you can pull up the menu then you probably are on the wrong input. Are the fans running when you turn it on? IF fans are running might be lamp, if nothing is seen through the back.
