Sony 46" LCD possible bad panel

[rmoody]

Got a 46" sony here and the left side of the screen is fading-snowy looking. Hopefully the pics will show the problem. I had a good spare tcon so I tried popping it in but it didn't change anything. At this point I think it's got to be the Main board or more likely the panel. Just want some input from the pros first.

Re: Sony 46" LCD possible bad panel

Have you tried with a source?

If the left hand side is slow to update, it's very likely the panel. If it's a KDL series, even more likely.

I was pretty sure that's what it was but wanted to be re-assured before i scrapped it out.

What is the exact model number? My friend has a 52 inch model and the 46 inch version had some sort of recall/extended warranty.

Search for your model and sony extended warranty or recall.

What is the model number, other than KDL series.
If the screen is slow on one side, which is the way they fail, it may be fixable. I have fixed 4 out of 4 so far....

KDL-46V 3000
Did you do the rubber tabs above the bad bonds? If so how long do they last?

Re: Sony 46" LCD possible bad panel

I have fixed 1x KDL-46S4100, 2 x KDL-46W3000, 1 x KDL52W3000.
After closing them up, none has failed. The longest ones (worked on 2 at the same time) are still ok after 6 months. The best one (52 inch) took 10sec. to find the sweet spot, 10 minutes to attach the bumpers. The difficult one was a couple of hours but that had been worked on by another tech who failed to fix it. It takes a couple of hours to get it all opened up and ready for testing tabs.

The trick is to find the material with the correct amount of pressure that will not compress after a while and then not press on the tabs. I have not resold any of these sets because I am not sure of the life of the repair. Just using them as home sets and selling off the others that I know will last a long time after repairs. The first few attemps did not last longer than a day because the material was not right. I now use a clear flat vinyl bumper about 1/8 inch thick, cut to fit in the groove of the screen frame. I use the screws on the frame closest to the bumpers to adjust the pressure.

Re: Sony 46" LCD possible bad panel

I had the 52 kdl series. I made up aluminum spacers and went with the foam tape and so on. I tried everything but the heat gun.

It lasted 3 months and was affected by temp.

If I play with it I can get a picture but it doesn`t last.

I thought Sony was going to warranty/recall these panels?

Re: Sony 46" LCD possible bad panel

One owner told me no offer from Sony (estimate was 800-900$ for a replacement panel), the other said he was offered a discount on a new Sony TV. Sony is a premium product and he could buy another good brand name for a little less than the discounted price from Sony.

Lots of people don't want to buy another product from a manufacturer that already burned them. Sony or Samsung or anything.

Personally, I will never buy another Chrysler car after the first. It's been over 30 years. Same after my last Ford in 1990.....

Re: Sony 46" LCD possible bad panel

Forget the aluminum spacers and the foam tape. Try vinyl bumpers. I tried lots of different things and none work as well or as long as this.

Re: Sony 46" LCD possible bad panel

I bought them from a local store called 'Crappy Tire' They are not in the USA under that name. It is just a 1/2 inch diameter clear vinyl flat bumper about 1/8 inch high. Comes 12 to a pack. Should be able to find it in a good hardware store like Ace.

Can I ask how you are testing for the pressure point? Are you laying the set down on its back or upright at an angle?

For those interested, it is Canadian Tire, but some people call them by their other name.

The part number from the description above is 46-0723-2.

I haven't really done anything with the set yet. I'm going to tear it down when I get some other sets out of the way and have more room.

Heh, didn't they try and sue over "crappytire.com"?

"The term Crappy Tire is a slang expression derived from the Canadian Tire trade marks [and is] frequently used by younger Canadian Tire customers," the company said. "In the vast majority of cases, the usage does not have a negative connotation but is an impertinent reference to a mass merchandiser." http://www.cbc.ca/news/business/stor...re_010531.html

Re: Sony 46" LCD possible bad panel

I could start with my most recent experience with Crappy (in the negative sense) Tire, but I don't want to derail this thread too much.

Let's just say it takes one person or "mechanic" in this case for me NEVER to use Crappy Tire for any type of car work again. For other things, I will continue give them my business. In fact, tomorrow, I'm buying a car battery charger for 50% off.

Re: Sony 46" LCD possible bad panel

Don't do it.....if it is their brand, it will probably damage the battery or catch fire or be involved in a recall after it burns your house down.

Re: Sony 46" LCD possible bad panel

This guy is selling his Sony Model KDL-46V3000 because of image issues. I'm wondering if anybody can give me some advice on whether or not this tv can be fixed within reason and if I should snap it up or stay far away. "Sound is good, screen can display picture, but part of it is broken as show in the photo, the left 1/3 is good, the middle is a bit red, the right side has vertical lines"
What I want to know: Is it a simple fix, or will it require a new panel?

He also says that it's like this as soon as the set is turned on.
