OLEVIA 232-S13 black screen slowly fades to vertical colored bars

[triplefour]

never seen this brand before in my life. have you?
when i plug in the tv, i get a blue standby light on the power switch.
pushing that, the blue light goes away and i see the backlight come on but the screen is black. then slowly, over about a minute or two an image fades in / lights up of colored vertical bars.

so what is it? TCON, Mainboard, or Panel?

i havent gone as far as measuring voltages yet, wanted to get some gut feelings from the crowd first, maybe take some bets

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

can someone please look at this and tell me whether its motherboard, tcon, or panel?

Do the bars move around?

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

no they are completely static

Sound ?

Olevia made some good stuff back in the early 480-720p monitor days. I have had a few they are pretty well built.

this is an ATI boosted display, my guess it would be a mainboard as the ATI Panel mainboards failed quite a bit on these and Westinghouse panels.

Dissconnect the T-con from the Main and see what happens, also disconnect the left/right TFT ribbons from the t-con and see what shows up on the blank side of the screen.

I have yet to see a panel failure with an Olevia but it might be possible!

I get no sound (using the usual n64 test, turning volume up a bunch and pressing source as many times as i could bear) so I'm leaning towards motherboard. I disconnected the tcon and just got a black backlit screen...the tcon is hard to get to so I haven't tried disconnecting one side at a time from the panel yet...

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

ok i tried disconnecting one side of the tcon at a time...
pictures of what it looked like:

Hard to see whats going on as the picture is so close, but the first one looks like a possible bad panel.

Can you get a distance shot?

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

ok heres the pictures
1. both cables connected
2. left side disconnected
3. left side disconnected
4. both cables connected again (left side looks different than in pic 1?)
5. right side disconnected, left side is also "moving slightly"

so whats it look like? i already know i have a motherboard problem because i cant get any sound to come out when i switch sources...

starting to feel like i got a lemon on my hands here

How much is a mainboard ? I might try it depending on price.

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

well it looks like i can get one here for 25 bux http://www.ebay.com/itm/171386667787...%3AMEBIDX%3AIT

but shouldnt i at least TRY to fix my main board first?

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

Good luck - mainboards are notoriously hard to fix. Check the voltage regulators if any and fuses if any then try heating the main ic with a hairdryer see if anything changes. Beyond that if nothing is visibly wrong then there isn't much you can do.

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

Yea I just realized this tv has too much screen damage to be worth buying a new main board...guess ill part it out but I can only be sure the psu and inverter are good...

[triplefour]

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

i decided to buy the mainboard anyway since it was cheap ... now i get sound when i change source but i just get a completely black backlit screen....
is it possible i had a bad motherboard AND tcon?
or is it possible that this motherboard is bad...
how do i tell? because if its bad i only have 14 days to return it

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

any ideas on a quick way to determine whether its TCON or Mainboard?

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

I put a bet on panel fault.

[triplefour]

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

well i found a TCON for 9 bux so we'll know soon enough. care to wager any money on that bet?

Re: OLEVIA 232-S13 black screen slowly fades to vertical colored bars

Sure! if I win you ship me one of your Vizio 32" Plasmas! /wink

My bet is panel.
