Have a wd60638 changed the lamp because old one busted now the TV works fine for about 3-5 minutes starts to hum and a clicking sound and pictures begins to flicker with colors going in and out


normally no bulb will bust ever unless you have oil on the lamp. sooo , it got too hot then. even if the fans turning its not putting out.
check the exhaust it should blow a lot of air past the lamp.

Samsung hlr506 tv is humming is it the fan or light


The humming sound is usually indicating a color wheel issue but could also be a fan. The best bet is try to determine which arear the sound is coming from. If non of the fans have that sound then the color wheel would be suspect.

The unit now has a very low but noticeable humming noise when it is turned on... and does not go away. Its almost like a bad or obstructed fan? - christopher buchanan


This is a LCD tv,it dosen't have a fan inside this tv.The humming sound u hearing it is comming from the tv power supply board itself.Some how those high voltage transformers,in the power supply board are having gapping voltages tranmitting,when power up those transformers are going in and out of it highvoltage coils.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Humming sound when switching on TV


It is very possible it could be the fan. Do check fan and venting to make sure it is not full of dust and getting plenty of air.

Hi, we have a humming sound that is really loud,


Yes, its fan noise and you need to replace noisy fan.
Let me know exact model of your Sony TV and need to know what fan is producing noise to provide you part number and parts shop info to buy that fan.

Tv makes humming noise when on. how can I eliminate or reduce the nose?


Some of the larger TV's are DISH ready, meaning that they have the tuner inside for SAT TV. The SAT tuners often have an internal fan that makes a humming noise. If it sounds like something other than that, you might have a bad component in your sound circuit that allows 60 HZ hum through the speakers.


If it is a rear projection LCG TV it has a fan in it to cool the bulb. You will hear the fan if you listen closely. It usually cannot be heard over the volume.


The fluorescent bulb and electronics inside make humming sound naturally. Kinda like when you turn on a lamp, and some lamps make a low humming sound.

Loud Humming


It's possible a fan or a hard drive is going bad. When the bearings in those devices start to go out they a start making noises like that.
