Toshiba RPTV Problems (43PJ93B)

[A²]

Howdo,

Could anyone out there with one of these 43" Tosh's please help me?

I received mine from S&V about 3 weeks ago, bold, big and beautiful she is my pride and joy. I have her connected to her own mains spur (shared only by the player and amp) and away from any nasty interference.

She is exclusively connected to a multiregion Pioneer636D via RGB scart, and is not used for any purpose other than DVD watching.

My issues are as follows:

Firstly, once every 20 mins or so, the entire screen flicks black for about a 10th of a second. Sometimes it goes for longer without this, but its always three or four times per film.

Secondly, there's a little distortion about 20cms in from the left side of the screen, which appears as if the screen is rippled.

ºººº°`°ºø,¸¸,øº°`°ººººººººººººººººººººººººººººº

The screen suffers some convergence issues when high contrast areas cross this 20cm wide bar, and it affects pans by making them 'roll' across this section. Its particularly annoying as the widescreen mask is not perfectly straight where it crosses this area.

Thirdly, once in a while (every 20 mins or so) I get a series of brilliant white dashes that appear for a single frame in the widescreen mask. I think they're outside of the 16:9 area, so I'm not sure how they're getting there at all. They don't happen in 4:3 material at all. :rolleyes: They don't appear if I pause and step the frames at all.

Lastly, the built in speakers seem to distort really easily at certain frequencies. At the beginning of LEON, for example, the whole cabinet buzzes!

This last one doesn't really matter, as I don't use the set speakers ever, but I was just wondering whether anyone had any experience of the above, or may be able to advise if or how they might be fixed.

Other than that (and the fly which recently managed to get between screen and gun, thought it was a dead pixel until it walked across the inside of the screen... odd.) this is the most fantastic set I've ever had. If I can just sort out these niggles, I will be a sincerely happy man. Maybe I'm just being picky?

Well, cheers for any help you can offer. I'd welcome all feedback, even if its just, 'Don't know what you're on about. Never had that on my set!'

Thanks,

Andy.

Why don't you have a word with the folks at Toshiba. They tend to be pretty good.

Cheers Bob,

I'll give 'em a call. Was just hoping to find out if this was normal or not before pestering them. :)

Thanks,

Andy.

In the main, you seem to be having more than your fair share of problems. It is not unusual, it seems, to have problems with picture oddities on these bigger sets. I have a 32" tosh widescreen and I have had to do an awful lot of faffing about to get the picture how I want it ... and it still isn't perfect.

I have read though that the Tosh RP sets are not as simple to set up compared to Panasonic ... which, when you are having to play around with convergence etc., must be pretty wearing.

I even called out my local Toshiba engineer (well from an authorised Tosh repair centre) to look at geometry on my set and he said (and I quote) "Seems alright to me" and "that's about normal". He made absolutely no effort to check the engineers settings and didn't even bring a service manual "we only do that stuff at the workshop". All for £19.50 + VAT for call out and the first 1/4 hour :mad:

Hope you get sorted though.

The number for TV enquiries is 0115 9766958. Just spoken to a fantastically helpful chap about my set.

I get the white dashes you talk about on my set too. This is a replacement set, as on my first one the convergence was way out. The white dashes were present on that one too.

Why dont you give Sound and Vision a ring they have a customer service dept and they sent out a engineer pretty quickly to look at my set.

She is exclusively connected to a multiregion Pioneer636D via RGB scart, and is not used for any purpose other than DVD watching.
My issues are as follows:
Firstly, once every 20 mins or so, the entire screen flicks black for about a 10th of a second. Sometimes it goes for longer without this, but its always three or four times per film.
I get exactly the same effect with a chipped 626D connected to the RGB SCART. I'm pretty sure it's either the DVD player or the RGB SCART because I've never seen the problem on an analogue source. To rule out the RGB input as the cause of the problem you might like to try moving the DVD to one of the other SCART sockets or temporarily setting it not to output RGB. You could also try connecting a VHS to the RGB SCART.

FYI I've never seen the white dashes and I certainly don't get a distorted section of the screen. The only other problem I get with the set is a slight misconvergence in the bottom left corner of the screen. I can't comment on the internal speakers because I've never used them :) .

Cheers all,

Good to hear I'm not alone! :)

PJ, I'll try switching the source as spec'd, and post back here with the results. :) Maybe this is a limitation of the set? Certainly an odd one... :rolleyes:

Dinghiy, Thanks for that mate. :) Would you be able to tell me what player you've got her connected to? Maybe this is specific to the Pioneer/Tosh/RGB combination.

Bob. Cheers mate. :)

Keep 'em coming. Looking forward to sorting this now! :)

Andy,

A thought about the ripple. Is there any (electro-) magnetic source situated beneath the TV at the point of the ripple? I ask because the projection tubes are located at the very bottom of the set...

[A²]

Cheers my mate,

I'll check that tonight. I've not been up to the DVD room in the last 24 hrs due to the issues arising in the US. :(

Puts a bit of perspective on my little ripples....

I am using Pionner 717 connected via RGB. I have tried other cables but it is still there.

Also tried a Pioneer 535 with the sae effect. Hmmm if other people arent getting this I might try a Wharfedale to see.

Let me know how you get on.

Cheers

I finally got my new 43" Tosh delivered yesterday to replace one which was "stuck in standby mode" and I am deleriously happy.

I also noticed the white flashes in the black bar area of widescreen films, but accepted them as a necessary minor (VERY minor) inconvenience as they were few and far between.

I'm using a Pioneer 515 (silver region 3 verion), but have not been using the set long enough to notice if it is just films on DVD that display this effect, or cable signals as well.

Have had no convergence problems or ripples (used the menu to set up convergence) although there does tend to be a very small area which has slightly less focus than the rest of the set. I am assuming that this is due to the large area of screen -the eye can pick out imperfections easier.

Films I've been most impressed with so far on my Tosh have been A Bug's Life (4:3 version) - looks almost 3D in its clarity

The remastered R1 version of the Shining

R1 Fifth Element (2.35:1)

Farscape Tv series -my God.. this looks incredible. The level of detail is mind boggling. I felt as though I were in space!

It has been a real wrench to drag myself away from the TV long enough to surf the net for a while.

I've seen these white flashes on my Tosh 28" CRT screen. Used to happen a lot during gunfire in Aliens - the whole screen would lose vertical hold and flash for 2 or 3 frames.


Only used to happen with a Samsung 709. Went away with a Pioneer 737.

[A²]

Right. @rse back in gear.

Just called the number Bob gave and got a friendly, if not entirely informative response. Blokey said the ripple was certainly not a feature of the set and that it was faulty. He also said the black frame drop/shut off/weird thing was likely a symptom of 100hz.


Hmmm... these sets are 50hz, right? Swat-eye-thort.

Tosh advise I give S&V a ring. Maybe they'll suggest I don't blink?

Hmmm.. Refer madness.

Cheers all, will let you know.

Andy.

[A²]

Ok,

Well S&V have been less than fantastic by promising to arrange a service blokey to call me, who then didn't and I've had sweet fahita out of them since then....

As it happens, the black flash doesn't happen in 4:3 material at all, so I'm figuring its the set trying to switch away from widescreen for a millisec, then back. Sound about right?

Now composing a mail to S&V to let them know I'm not too happy with their c/s.

Bad day. Bad Mood. Lousy Hair.

...and they're still not replying to emails.

Grrrrrrrrr.
