Re: Jmb jtc012600102b

One of the more impractical cameras ever invented.

Re: Jmb jtc012600102b

Easy to attach though

Re: Jmb jtc012600102b

Indeed; I just laugh every time I go to a party with my brother he always uses his iPad to film video... it's a strange sight!

This help

Re: Jmb jtc012600102b

OK, those components aren't there then.
Check R244 has a solid connection. (It should read zero ohms.)

[Mtek325is]

Re: Jmb jtc012600102b

Yes zero ohms

Re: Jmb jtc012600102b

This is getting very strange. At one end, you have 3V, the other end, you don't. Can you check for continuity from pin 7 of PL200 to pin 12 of PL201?

[Mtek325is]

Re: Jmb jtc012600102b

no continuity between the pins

[Mtek325is]

Re: Jmb jtc012600102b

what about a jumper between the pins maybe.

[tom66]

Re: Jmb jtc012600102b

You probably have a break in the trace or a cold joint somewhere. Follow that line from R244 very carefully and look for breaks. You could easily run a jumper to the main board connector (long piece of insulated wire would do) and this should sort the issue out. Very strange problem!

[Mtek325is]

Re: Jmb jtc012600102b

tried the jumper and it works, well the screen is lighting up anyway

[tom66]

Re: Jmb jtc012600102b

Well, a very odd fault to track down indeed, does everything else work?

[Mtek325is]

Re: Jmb jtc012600102b

no thats the thing ive tried the ps3 in it and nothing. the buttons beep on the front but no menus come up etc

[tom66]

Re: Jmb jtc012600102b

I think you need to check where the break in the traces occurred or where the cold joints are. If it broke more than the backlight traces the main board may not be receiving all the supply rails. Also reseat all connectors etc. Maybe TV was dropped and this cracked the PCB? Should still be repairable, just need to trace down where it occurred. Common places are around screws as there is a lot of tension there.

Re: Jmb jtc012600102b

Re: Jmb jtc012600102b

If you ever get a tricky project you want to give up on, I work in Basingstoke 9-5 at an Electronics Engineering/Design company (internship) and will be quite happy to buy them off you. Always on the look out for TVs to fix. Recently, I started keeping a lot for myself and friends, selling them on at near cost price, which does mean I have a large, umm... "backorder"!

Got basement & living room plasmas sorted, now need smaller LCDs for each bedroom, each hooked up with Raspberry Pi XBMC to the network and streaming 1080p content over the network.

Re: Jmb jtc012600102b

haha ok ive just started in this really and im enjoying it as a hobby so there should be more on the go soon, i dont like giving up though but then i got this sammy plasma which is becoming a bit of a headache...plasmas just cost too much for parts but ill give it another go hopefully one comes up with a smashed screen on ebay. cheers for your help mate.

Re: Jmb jtc012600102b

sounds good i want a decent nas drive to stream around the house and hopefully a mini pc for the back of the living room lcd with windows 8 installed
