Re: Polaroid 37" making loud squealing noise/black lines through display

2 1/2 years later and the set is still kickin'

Still has the bruise mark (I think it's a heat mark actually, it's gotten worse since I fixed the caps). I barely notice it now though. It's not my main set, just a bedroom TV to watch before bed.

Good luck with the caps, it was a cinch to fix them. I may need to replace mine again soon (or just toss the set). After being on for a while, if I turn it off I have to let it cool down before it will power on again.

Yeah, it was a nice quick fix to repair the bulgers, from searching around it seems to be a common issue with this set. Works like a charm now! Squeal is gone, and starts up within 10 seconds, where before it was almost 30 seconds before anything showed on the display.

As for the heat gun, would that potentially work? I'm not too keen on taking the panel out unless there is a possibility

Re: Polaroid 37" making loud squealing noise/black lines through display

Here's the pics, it's kinda hard to capture the streak, as it doesn't appear unless it's a certain colour/brightness. If it's full on white, you can't see it, if it's dark you can't see it.. It only shows up with in-between shades.

In the first pic, you can see it in the purple panel to the right of the guys head (the blur at the bottom was just me removing the advertisement's website). You can see it in all of the pictures.

I don't know if it was related to the cap blowing...

Re: Polaroid 37" making loud squealing noise/black lines through display

Replaced the bulgers, the set is now working awesome! The black streak is still going through it, I'm thinking it might be physical damage to the screen now though.

If anything else goes bad, I'll replace the rest. Thanks a bunch kc8adu!

Hey all,

First time poster here. My parents recently bought themselves a 46" Sony LCD, and gave my wife and I their old Polaroid 37" as it wasn't working. As the title reads, when you first power it on, there is a very loud squeal that comes from the speakers. If the TV is muted, the sound stops, but continues if unmuted and the volume is set to 0. There is also a faint black strip (it's not a straight line, it's more curvy than anything) on the right hand side of the display.

Anyway... Being as it was a free LCD TV, I'd like to see if I can get it fixed...
