Toshiba Jumpy picture problem w/Photo of problem

[bigzo]

Here is an update of my problem with my Toshiba 50H81 with a picture showing whats wrong. I had a Sears tech look at it and he said I need a new PCB(Plug in) which is $160 and a new Module which is $400 bucks. Told him I'd wait for another opinion before shelling out that much money. Any info anybody can give me would be appreciated.

I've had my 50H81 for 2 years now. I started having a couple wavy lines at the top of the screen a few months ago when I would turn it on. I figured it wasn't a big problem because I thought it was jus warming up and eventually the picture would become straight. Well, a couple days ago. It got worse. Now the whole screen is wavy, the picture is jumpy and a couple vertical white lines run through it and it doesn't get better. when I put it in POP mode the picture on the right is perfectly fine but the picture on the left is the same as when it's not in POP. Anybody got any ideas of the the problem might be??????

Well, since the picture on the right is fine, It may be an issue with one of your tuners and not something that affects the whole TV. Does it do this with other inputs like a DVD player, VCR, STB?

Make sure you show this to any tech...

[kevinw]

Start using a HD tuner or just the the analog tuner that works. How often do you use POP? Try using the the other input. Check your wires also. Make sure everything is tight. How are you getting your signal?

[bigzo]

It has nothing to do with my input. Even without anything at all hooked up to the tv(component, composite, s-video, or regular cable) it still has the lines and the problem. I've also tried running a signal through all the inputs(DVD, VCR, Playstation, digital camera, cable) to see if that had something to do with it and it didn't. The only time the picture is somewhat decent is the POP picture on the right, or when the resolution is set to 1080i through my OTA HD Tuner, but the picture still bends a little in the corner in 1080i.

bizgo,

My 42H81 is doing EXACTLY the same as yours.
Started out doing it only on warmups.. now it's perminent.

i think 500 is getting off cheap for what it cost me new... or to replace..

many thanks

It does it for ALL inputs except Video 2 and Component 1? The corner bend is most likely a geometry issue. How is the ovescan?
It looks like a 650 dollar repair OR get a new TV, which might not be bad idea because the 50H81 is soon to be a 4 year old model and so much has changed since then. Like DVI and multipoint convergence moved out of service mode.

'lo Kevin,

& thanks for your response. I'm also holding out for bizgo's response. His described symptoms are verbatim what I'm seeing here w/ my 42H81. And a $650 repair is still preferred to a $1500 replacement. (imho)

I'm holding to see if he went through w/ the repair or replaced the set. If I can get a bead on the replacement parts (source/cost) then I'm up for serving the set my self.

Again, my thanks for your prompt reply.

cheers!

I am seeing this *exact* issue with my 57HDX82. As others have said, it shows on every input, regardless of source or cabling, but the right POP window looks just fine.

Right now the picture gets progressively better as the set continues to warmup, but takes a least half an hour to become watchable.

Just like bigzo's original post, my problem started as a couple of wavy lines at the top of the screen, beginning about a month ago, that went away very quickly at first. But this overall issue is continuing to get progressively worse on my set (longer time to stabilize, etc.) as time goes by.

Any other info or ideas would be much appreciated by those of us seeing this issue.

thanks in advance

'lo MIB,

I purchased the service manual for my unit (it doesn't cover the 57~). It will contain a 'parts & assembly list' which i hope to use to pin down the replacement items.

<> there are NO Toshiba service locations in my state (va)
<> I payed 1300+ for mine in 2001 so a 650 service will be preferable to replacing it this early.
<> I'll post feedback here (or in a new post) w/ my progress.

Hmmm...I have the same set as yours but no problem. When did you take delivery? Any extended warranty?

First poster bigzo shows us a picture with PIP showing us bad picture on the left and good picture on the right. Therefore he has a STB with 2 tuners, or has analog cable connected directly to TV. What is your STB and if you activate PIP, do you get a good picture on the right side? If so, if you SWAP the PIP will the good picture now on the left remain good or not. If it does, press PIP again and see if it remains good. If your STB carries 2 tuners, there may be lies the problem...tuner 1 rather than your TV.

[GrepZen]

'lo Michael,
<> I've no idea what an 'STB' is.
<> Until the service manual comes, I've no idea if the two tuners are separate items let alone swapable.
<> MIB and I both used the term 'exact' in the comparison of our symptoms to bizgo's.. yes.. our 'PictureOnPicture' shows right hand clear. (I'm perhaps speaking out of turn for MIB.. )

Rantlet:
Now, I'm certain that this is a manufacturing problem rather than my tv dying of old age ... at 3 years old. And that, I 'need to purchase' a 3yr warranty speaks volumes Toshiba's dedication to quality.

[ManInBlack]

Thanks for the responses...

mfabien: Not using any STB; analog cable directly connected to coax input on TV. Crappy picture stays on left at all times in POP mode, even when swapping channels.

GrepZen: You didn't speak out of turn at all...thanks!


KIM that this display issue occurs when using *ANY* input, including component (progressive DVD, and other sources), s-video, and composite. I would think that eliminates the tuner as a potential source of the problem.

BTW2: I also know for a *FACT* that my cable TV source is coming across cleanly, since I have downloaded shows recorded by my ReplayTV unit since this issue has manifested and there is no distortion whatsoever in the video.

BTW3: TV was purchased April 2003, and my wife swears up and down she got an extended warranty at purchase (it was a gift for me), but we can't seem to locate the paperwork. Doh!

You should be able to call the store it was purchased at for a duplicate receipt and contact info for the extended warrenty provider....

[GrepZen]

The manual(s) have arrived...

Anything new to report from anyone seeing this issue?

Thanks in advance!

[GrepZen]

MIB, appologies for the delay. I'm still trying to understand the manuals a bit.. they don't cover troubleshooting but have some detailed drawings of the components. Once I can match up what I've read above w/ what's in the manuals, I'll be exploring the possible sources for parts.

failing that, I may just start replacing components --ACK-- I really don't want to buy my 2yo tv AGAIN..

[ManInBlack]

No worries GZ. Thanks for the reply.

I actually sprung for the service manual CD myself (ordered from Pacific Parts) a couple of days ago.

Just waiting for it to arrive...and trying not to go cross-eyed from the wavy lines at the top of everything we've been watching nowadays.

[GrepZen]

I've set my unit on POP, set the main source to some blank, and just watch 1/2 of my tv. --so I'm only making 1/2 payments to the good folks at BestBuy in honor of it all.

[mindtrix]

Oh great, I have just literally within the last week, been getting red glitches in the screen and its also exhibiting the few wavy lines at the top of the screen for the first couple of minutes. Has anyone narrowed this down component wise? This really sucks, its just a couple of months removed from warranty too..

[GrepZen]

& the hits just keep on comin'

3 weeks ago, the 2nd display started it's wavy display.
Any one want a 42H81? only one bullet hole.. lil'bondo and it's great fish tank.

[wfrandino]

I paid a guy $70 bucks to tell me it is the "Hyper Board".

Then he tells me the part is unavailable and he is going to re-build the part from components and that it will run $400...and he won't give me the part number so I can find it on my own (for him).

Needless to say i didn't give up...Tritronics in Maryland tell me there is only one part on the 42H81 called a "hyper board"...it was part #23786198...but that was discontinued and is replaced by #23148017 which is available and costs $171.21

These guys are Approved Toshiba parts providers. The repair man I had look at the set said that company is not one he has relations with so he won't entertain the idea of ordering through them???lalala

Another guy I called said if that was in fact the problem and that was the right part...I can probably replace it myself with little difficulty.

What can any of you guys with the manuals tell me about the "Hyper board"? or part #23786198 or part 23148017...(ie. where is it located in the TV?)

Thanks,

Bill

[GrepZen]

Bill,

I can get the info for you.. can you PM or send your email? --obfuscate it of course.

[GrepZen]

If this is 'identical' to the issue as I experienced it.. you can get a good picture out of the 'POP' function.. and watch 'half' of your 42" set.

If you procrastinate, you'll get some 'burn-in'. --either fix the hyperboard asap or scrap the set. --I did the procrastination part with expert skill.. and 3 tubes ==250 each and the 400.00 repair put the fix right over the edge for me.

best of luck to your situation.

Look here for specifics on how I fixed it. I had the same problem.
