Re: Polaroid flm-3732

What else should I test?

Re: Polaroid flm-3732

So what DC voltage do you get on that large cap? That will be the first place I check after checking to see if it has blown main fuse first.

Re: Polaroid flm-3732

Both fuses on psu are good

Which is the main cap?
Is it one of the large caos on its side?

[budm]

Re: Polaroid flm-3732

The two big one laying side way, measure right at the two legs.
If you do get 160~170vdc, then check and see if you do have 5V STBY at the 5V pin of the connector.

Re: Polaroid flm-3732

Ok so the tv powers on and panel comes on
I did get 167v at both caps

Im guessing either the spilled over solder from the previous repairs was causing it not to power on or there was an improper connection somewhere

So now on to the issues

1. When I do the auto search it goes into search mode but it does not find any channels
I tried both "tv cable" and "hd cable" connection and auto searched both and I dont even get one channel

2. When I connect my sons ps3 via hdmi cable it does not recognize it. At first it would show a bunch of distorted colors then it the screen blacks out and goes back to the distorted colors then finally just went to a blue screen and the top right corner said "not supported "
I did hook up my sons xbox 360 slim via hdmi and rca cables and it worked just fine

So what should I check to fix these issues?

[budm]

Re: Polaroid flm-3732

"not supported " That means the resolution setting of PS3 is too high for this TV to display (same kind of thing with PC monitor if the video card resolution is set too high).
I am not if this TV has QAM tuner to pick up the Unencoded HD signal or not, the analog signals are take away by cable companies months ago.

Re: Polaroid flm-3732

This tv has 2 cable connections
I tried both auto searches and got nothing

So does that mean I can only use this tv just to watch movies with a dvd/ bluray player only?

Or do I need a converter box?

[budm]

Re: Polaroid flm-3732

It does not have QAM Tuner, it only has NTSC, and ATSC (Over the air Digital). You need the cable converter box.

Re: Polaroid flm-3732

I sold a 720p Samsung with the same PS3 resolution issue. I don't have a PS3 myself, but the buyer had issues getting his PS3 to work: http://community.us.playstation.com/.../td-p/18790954

Re: Polaroid flm-3732

Well that sux I guess I will keep the tv for my room

Too bad I cant install a tuner

So what is the HD air connection for?

Im a bit confused
Does that meani cant connect a cable box?
Because I was just running the coax cable to the tv like my other tv

[jose6326]

Re: Polaroid flm-3732

i spoke to the previous owner of the tv
he said he had an HD direct tv box with hdmi cable to get channels

but at least it works

thanks everyone for the help
