Default Thanks for the help/Progress

Hi guys. I know this is an old thread but I just want to say thanks for the help. I have a Toshiba 52RV535U that had vertical line on 1/2 the screen. I am sorry that you had to spend the money replacing boards with no success, but because you did I didn't have to. I ended up removing the front bezel and metal frame around the LCD panels. One on the ribbon cables on the top board was the problem. I found that pushing on the bad cable would "solve" the problem. Don't be mad at me but I just put a piece of electrical tape on the cable and so far it is working. I know it is not the best fix but if it works I don't care. I will keep you updated on how long the fix lasts.

Default similar problem

I have a similar problem with my 52RV535U, with intermittent lines down about 1/8 of the screen. Sometimes the picture is fine, sometimes it's not.

I'm pretty sure that the defective part is one of the brown flexible cables that connects the circuit board on the top of the TV to the panel itself. If you look at the flex circuit, you'll see a small metal rectangle in the middle, which gets really hot when you turn the TV on. This is a so-called LDI chip - a LCD Driver Integrated circuit.

...so my guess is that the LDI chip is glitchy, but I don't have any way to try and repair it. Since the flex circuit is bonded to the LCD panel, I can't just pull it.

I'd like to try cutting a flex circuit from another broken 52RV535U, and swapping it into this one. It's going to be damn near impossible to get the alignment right - the wires in that flex circuit are hard to make out even under a 10x lens, but I might as well give it a shot.

Does anyone want to get rid of their non-working panel?

Default So...

I tried to disassemble the TV and got as far as getting the back off. Can someone help me figure out how to get the front trim off?

I am working on this problem as well. Could there be two issues, one involving the panel, and another involving the ribbon cable connection? I wonder whether there are any tale-tell signs hidden in the vertical lines.

I can help you get the plastic off of the front. Send me a PM and we'll chat.

Default Toshiba Regza 52 inch (52RV535U) - Third of Screen with Vertical Lines

I want to confirm the success of what others have done to increase the life span on this line of TV's.

-Mainboard tested: Passed but no change to picture.

-T-Con Board tested: Passed but no change to picture.

-Reset LVDS Cables (these attach to T-Con board: Passed but not change to picture.

The following steps were taken to "FIX" the TV.

1.) Detached the plastic bezel (frame) from front of TV exposing a metal frame with screws attaching it to TV.

2.) Removed all screws (metal is soft so be gentle and make sure your screw bit has a snug fit).

3.) Carefully removed metal frame exposing LCD screen and 8 ribbon cables (different size TV's have a different number of ribbons cables) that were attached to silicone board across top of TV on one end and on the other they were attached to LCD panel.

4.) Turned TV on until vertical lines were present.

5.) Systematically pressed a pencil eraser against each of the 8 ribbon cables, pushing them gently from center toward back of TV, and observed screen for changes.

6.) In my case I found it was the fourth ribbon from right of the front of TV.

7.) Use a piece of electrical tape to hold tape in a spot where vertical lines disappear. If necessary, use some small object to press against the spot and tape it to put pressure on it and thus the cable too.

8.) The bottom corners of the LCD panel ought to be setting on a ledge and not dangling, be sure they are on the ledge and secure them with tape spread diagonally across the corner of the panel. (You do not see a certain amount of the LCD screen when the plastic bezel (frame) is attached so do not worry about covering some of the LCD panel with tape on the bottom corners).

9.) Do NOT reassemble TV but wait until YOU feel satisfied that putting the TV back together is worth the risk of another "vertical line" flare up.

So far I have had success though I have had to occasionally add more pressure and tape the ribbon over again.

I hope you have the same success; I did call Toshiba 5/5/2012 and they still do not have anything in place for a recall. The representative I spoke with directed me to a case manager to call since she did not have authorization to replace my TV. My suggestion is that if you have not called, do so anyway and at the very least request to file a complaint.

My complaint consists of the following.

1.) I buy TV's for quality and if I wanted a warranty longer than 1 year I would have bought a brand I viewed as lesser quality and paid for one.

2.) It is understandable that sometimes TV's have issues but when I do a Google search of my TV's model number, "52RV535U" PROBLEMS, and the first three results are "VERTICAL LINES" that communicates a consistent problem and a predominant one.

3.) If the consistent problem were a power board, main board, T-Con board, LVDS cable, infrared board, or speakers then I can understand, I might shell out $200 at the VERY most because that is what those parts cost, HOWEVER, when the consistent problem is an LCD panel with a cost over $1000 for parts alone, this is a major repair I expect the manufacture to cover.

4.) Bottom line, if this is the kind of quality product and service that Toshiba is going to manufacture and not offer any recompense, then my opinion of Toshiba is now soured and I will be sure to communicate my experience of them.

Hi guys. Non-techie guy here. I've got a 47" Regza I've had for a few years, I think it might have a similar issue but am not really sure. With my TV, it's a single vertical green line, about an inch from the right side of the screen. It's there on startup, stays for a little while then disappears.

I've had the problem for a few months now, it doesn't seem to be getting any worse. Is this the same issue as I've seen on this thread?

Thanks for this. I'm about to buy one off of Craigslist for very cheap (52RV535U) and have a run at fixing it. I've watched a few Youtube videos such as this: /watch?v=8P_i-JIsrYA&feature=colike and feel like possibly replacing the bond tabs that hold the cable in place. I will update my progress as I work on this project.

My 52RV535U TV also developed the same problem recently. I can open the back cover easily, but the front cover can not be opened easily and I am afraid of removing the front cover by force to cause damage to the system. Can you share with us how to open the front cover?

My fix from above with the piece of tape lasted about 4 months. After time the tape was no longer about the keep pressure on the cable. I am now going to put some shims between the cable and the metal frame. I am hoping this will be a more permanent fix.

@d3v: do you a link to that video you mentioned? The url you posted does not work.
