Toshiba 42WH36 convergence prob + interference

I've just received a Toshiba 42WH36 but have 2 problems with it. Firstly the convergence was pretty bad, so I've been trying to adjust it through the menu, however this is proving tricky to get just right. Is it a feature of RPTV's that this can never be spot on?

My 2nd problem is I appear to get interference from BBC2 when watching SKY (via scart) from the TV arial. Goes away when I unplug it. Anyone else had a similar problem?

thanks

Stephen

Not sure about your interference problem but the convergence ought to be manageable.....there is a simple user level convergence menu,and a service level menu also,for the brave hearted.....if you haven't managed to get things right with the user level convergence,and you've only just received the RPTV,I'd strongly suggest getting the supplier to get a Toshiba engineer out to you,to correct the problem,rather than going into the service menu yourself and potentially invalidating your warranty.

search on the forum.
You will find how you can easily fix the convergence in the service menu.
I did it and im very satisfied.

The reason I suggested a call to the suppliers/Toshiba in the first instance is that the RPTV is new,and thus under guarantee which will be invalidated by fiddling around in the service levels.....if this isn't a problem,then as Bolle suggests,a search here will provide all the information you need.
If you do,be sure to write down all of the service level values before making any changes,so at least you have something to revert to if you press the wrong button!

Update: Rang toshiba, they explained the converence needs doing for each picture type (wide / cinema / 4:3 etc...) so I've tried that but it hasnt helped. I've noticed its just the red that goes out of alignment. I have to ring Comet now to ask their advice.

Phone them back and tell them that the set needs a service level convergence done in all modes.
When I first got my 42 I tried the simple level convergence and no matter how hard I tried I still could not get the crosses bang on. Since then I have done a service level convergence thanks to Demons instructions and believe me I was stunned when I learnt how easy it was. It really should be in the normal menu.
I agree with Alexs2 that as the set is new get them to do it.

I had a vaguely similar problem with picture crosstalk when watching Sky on External 2.

This was fixed by changing the External2 output to "Monitor" (it was originally set to "TV")

With a better scart lead this shouldn't cause problems but it made a big difference in my case.

If this is the problem however, it doesn't explain why the interference is always from BBC2?

Thats cured my interference problem, thanks johnjackthom. I'll get a better scart lead as well as the one I'm using for sky is pretty cheap.

thanks again

It took me a while to get the convergence sorted on my 46WH08 but at the time (2 years ago) I found a few helpful hints on entering the service menus by searching this forum.

I would imagine all the Tosh RPTVs have similar adjustments.

Edit: Try a Search by User Name for posts by Demon and you'll find loads of info including how to get into the Service Convergence mode.

Comet have sent someone around and he agreed the convergence wasnt ideal. They are going to send out an engineer. Seems that quite a few of these tv's need the convergence tinkering, toshiba should really make a better job of it at the factory.

Angry Arrrgghh!!! 42WH36P giving me problems

Took delivery of the TV yesterday, and found many issues.

I personally managed to get the convergence settings spot on. No problems there.

The issue I came across is that after a few seconds of switching the TV on, I get lines appearing across the entire width of the screen intermittently, like scrambling lines, sometimes the lines cover the entire screen, sometimes the screen entirely clear.

Now it has evolved into the screen blurring out, like the focus has gone.

Very annoyed, engineer should around soon, but it is very frustrating because I was really looking forward to this TV.

Has anybody heard of this or experienced this? Is there anything I can do to fix it?

On a normal CRT TV, you've described a fault found in a line output transformer. In simple terms, it drives the tube to create a picture. Common faults are poor focus and flyback lines. It could also be the controlling IC for the lopt too.

Not sure on a RPTV, but as it is also CRT in nature, it wouldn't surprise me to find a similair fault.

Well, the issue has now evolved.

The lines now turn into a mass of what can only be described as green sin curves. The convergence of the three colours then seperates slowly, until all three colours are seperated from each other and the colours are portraying the movement on the screen independantly.

The screen then pinches from top to bottom convexing into a horizontal hour glass shape.

I guess the TV is buggered and I got hold of a dud. Hope the engineers call soon, as it is VERY infuriating. I'm hesitant to go into the service menus, but if the engineers do not turn up by Friday, I may have to.
