Tcl pdp42u3h

[Amraks]

Model: TCL PDP42U3H


Got this 42" tv plasma giving to me.

Issues so far.

1. No remote
2. Flickery when tv is in white

would this be a cold solder joint some where as its intermittent
looking for the manual can't seem to find one any ideas where to look?

thanks for reading and thanks if you can help me

PSU model: n3501q00150a


I thought I better add in that.

Likely bad 450V caps or bad 200-250V caps on primary and secondary respectively.

Re: Tcl pdp42u3h

I have fiddled with the v and y sync seems to have fixed it.

But now I think its the contrast might be set to bright.

Anyone know of if a harmony remote will work with the set?

sometimes I'm getting white lines flicker across the screen is this what these caps do when they go bad. its not very often but I'm thinking its when there is a heap of white being displayed.

Never had this fault before, but I think that could cause the problem.

By the way the PDP42U3H only has an 852x480 resolution - not HD. I can find these for £10 each in working condition.

Re: Tcl pdp42u3h

Thats 12 dollars Australian dollars.
I would near get 150 if I sold it as is but hey I need a flat screen in the lounge room.

Its probably going to be temporally until I get others come in, then I can probably get rid of it.
to the guy who thought it was broken because he found it next to the recycling skip bin at his work and it was pulled apart.

I will look at getting a remote today.

Go to Logitech and punch in the brand and model number and will let you know if it will work with it.

Really? That would be nice. Maybe someone dumb would buy it. A 720p 42" would be worth maybe AUD$150, but this is just a 480p. Still, it is plenty nice for games and SD (which most people watch.)

Re: Tcl pdp42u3h

well basically everything here on tv is nearly SD except for 4 channels.
So yeah after watching a vacuum tv I won't notice the difference.
Its not a bad tv playing the PS2 on it will be good.

If I was a retailer in Australia, I would not sell 480 line flat TVs, since they are primarily intended for NTSC markets such as North America.

480p is a standard for plasmas, NTSC or PAL. That means in the UK, a 42" plasma has a lower vertical resolution than a 28" CRT.

Re: Tcl pdp42u3h

Got remote then fixed everything

I have been keeping it switched off at the main power all week.

Now it has a luminescent green over all the white.
also some luminescent blue over some stuff.

Anyone got any ideas about where to start?

[Amraks]

Re: Tcl pdp42u3h

Found a schematic.

it does it after it heats up, any ideas?

[Amraks]

Re: Tcl pdp42u3h

worked that problem out.
Was playing with the screw things in the back of it.

and also found the system menu. where you can set the default colors.

Now I'm stuck with 1 second flickers.

found a better manual

Re: Tcl pdp42u3h

just fixed up an lg 42" plasma monitor.
had interference type patterns,white streaks,black streaks,and flicker.got to poking about with a scope and found all sorts of trash on regulated supplies.had to replace about 60 sm caps.
its perfect now.
set it up on a pc with dream aquarium screen saver and it sold itself.

Re: Tcl pdp42u3h

But I have re calibrated the Vs/Va pots they both equal the required voltage now.

But I do believe one to be going up down 270.0 to 270.2 is this normal?

should it be at a stable 270.0 on my multimeter?

Have I answered my own question?

270 Vs?! Are you sure?

[Amraks]

Re: Tcl pdp42u3h

190 Vs

sorry

[tom66]

Re: Tcl pdp42u3h

190 Vs

sorry

Is it stable during flickering? It should be rock solid. 0.1V max variation over full brightness - this voltage is directly proportional to picture brightness.
