ok my friend bought this tv round today and asked me to have a look at it he bought it off a guy on facebook it looks to me that the tcon is faulty due to the images some times goes solarized but it may also be the panel so looking for more advice please

p.s also when i took off the back cover ive noticed that someone has glued on 3 one pence pieces to the main board any ideas why ?

thanks

Re: Samsung ue40c7000

probably the soldering under the chips has gone and hes tried to aid cooling the adding the copper well thats my guess.

Re: Samsung ue40c7000

Could you show us a picture or video of what it does when it is faulty?
Are user menus etc. affected too?

@tom as you can see in the video solarized images and sometimes lines of blocks on screen but you cant see that in the video

Re: Samsung ue40c7000

Hmm, unlikely to be panel going by what it looks like. Have you checked the LVDS cable is properly seated both ends, no damage, bent/burnt pins, etc.?

Access service menu: from standby press: Info Menu Mute Power on remote, then when service menu pops up, select SVC, then select Test Patterns. See what, if any, difference there is between GENOA-P and NAPOLI patterns, and if there are other generators present check them too.

GENOA-P fault only: Main board pattern generator. Fault on main board or LVDS cable or T-con (T-con is unlikely but cannot be 100% ruled out.)
GENOA-P & NAPOLI fault: T-con board pattern generator. Fault on T-con board.

im checking the lvds cable now tom ive uploaded some pictures to show you that when i enter test pattern thats the only options im getting in service mode

Re: Samsung ue40c7000

Do you have options under CONTROL or CTRL? I am going by the US service guide, I don't have the UK one for this model.

You have to press "OK" to select Control option.

According to the EU service manual you should have FBE Pattern Sel, and Logic Pattern Sel. http://elektrotanya.com/?q=showresul...oria=&kat2=all

Try selecting "Panel Auto Setting" and pressing OK, I think the panel options may be wrong. Also try a Factory Reset.

Re: Samsung ue40c7000

yes tom i know selected the control option then you see the following

EDID
SUB OPTION
HOTEL OPTION
SHOP OPTION
SOUND
CONFIG OPTION

Re: Samsung ue40c7000

Ive also checked the lvds cable cant find much wrong with it

[sordids999]

Re: Samsung ue40c7000

also tried factory reset still the same the picture has a orange solarized effect plus some times you have slightly light white lines going across the screen

Re: Samsung ue40c7000

Since the behaviour in the service menu is different to the service manual, someone has been fiddling with this TV more than adding pennies to the chips (seriously, who thinks that's a good repair technique?!)

I think I see a Samsung panel sticker. What is the Panel Option under "Option" on the service menu? It should be AMLCD or SAMSUNG and the INCH OPTION should also match.

Did you try the "Panel Auto Setting" option?

Re: Samsung ue40c7000

PANEL TYPE 40A2UF7E
LOCAL SET EU_AII
MODEL UC7000
TUNER SEC_T2
FRNT COLOR T-M-BRN

and if i try the panel auto setting it goes to wait then quickly back to failure

[tom66]

Re: Samsung ue40c7000

Does the panel sticker say "LTF400HQ02"?

[sordids999]

Re: Samsung ue40c7000

yep

[tom66]

Re: Samsung ue40c7000

Hmm, try changing it to 40A1UF0E, any difference?

[sordids999]

Re: Samsung ue40c7000

no tom still the orange skin effect and solarized images

[tom66]

Re: Samsung ue40c7000

Any change to the test pattern options is what I meant, sorry.

Re: Samsung ue40c7000
