    Hey all,

    My setup...
    Running THHB's image.
    Open ATV 6.1 + internal SSD hard disk installed.
    2 sat feeds and an aerial feed connected - all working fine.

    I have random problems with pausing live TV. Sometimes it works, sometimes it doesn't! I am pressing the 'Time' button which is under the green button on the remote control. Sometimes a program will pause, sometimes it won't and instead displays the screen in the second pic below, this is very frustrating:mad: Sometimes changing a channel which I cannot pause and then going back to the channel will allow me to pause it. Can anyone offer an explanation of why this is happening please?

    Paused correctly

    Not pausing and this pops up on screen.

    Cheers:D

    I was out for weekend and came back this evening and my box is dead. Tried different power sockets and joy so I popped the cover off and noticed what seems like a capisator is gone by what seems like a leak? I could be wrong. Is it possible to get a new power board?

    If that is 'goo' rather than some glue then it appears there are three (or four) caps needing replacement.

    Sorry to be pain any recommendations for a 12V PCU

    Would THIS be OK ?
    It should be ok.
    The original psu is rated at 4.5A but I never measured the draw from it when the box is recording to the hard drive which I suspect would be max. I repaired another Tiviar yesterday that had dead PSU. I popped a 5A one into it and wired directly. It looks like a PSU for a laptop but is a 12V. It might be worth noting that depending on the PSU that you try some might not like the initial surge when you apply the mains with the output connected directly so I use the rear switch to apply the 12V dc to the main board. Plug in the mains and then use the switch to bring the box on.
    I intend to sort out the original PSU's when I get time and post the outcome so don't throw away your faulty PSU's.

    Odd brown stuff around many caps and wonder if the big one went.I would have thought when caps go they bulge up.

    Looks like the black cap near the top left looks distorted as you can see from the top.

    That's glue that has discolored with heat and time. No need to wory about it. Back in the 80's this caused a problem with some JVC VCR's. I found that it became conductive over time and caused problems with the system control IC's. Later on a service bulletin was released from JVC advising service engineers to remove the glue to cure some faults.

    Ahh yes as had to move laptop screen for better view and see top is funny.
    Wonder if that brown stuff is interlinked with the issues.

    That's not a cap, it's an inductor covered with heat shrink. It's vertically mounted and what you think is a bulge is in fact one of the wires running down the side to connect to the PCB.

    Thank you for that. Is there anything I could try to establish what the fault could be?

    Hi Payton,
    Unless you have a meter to measure the value of the capacitors they you are shooting in the dark. The easiest thing is to connect a 12V 5A PSU in there. You can even confirm by substituting the PSU with an alarm or car battery. Any 12v source that can deliver 4.5A is enough. Car battery can deliver 300A so don't get the polarity wrong if you try car battery.

    Yes.
    No surprise to me as I have been servicing down to component level for 35 years . In recent days with storms etc there has been a lot of power cuts, spikes and surges. Most power supplies go faulty at switch on. I have seen gear running fine for 10 years + and I arrive to say remove the TV for repair. I remove the power from their satellite box by mistake and then it won't power up. Try and explain that to the customer. If the caps in the startup circuit go low in value for example at power up when they are only required they you get a problem. With older switch mode power supplies you would get a bang and a puff of smoke at startup.

    Hi guys, just got hold of one of these, first look seems a nice "not so little" box, one quick question can you disable the light slashes on the front or is it a case of black electricians tape (its in the bedroom at the moment). I've been in the display settings and reduced all the brightness settings to 0 but no change. Thanks

    Yes you can dim the front display. I have vix on all mine.

    You can't dim the lights if you have changed over to enigma 2 (OpenATV, Vix...). If you're still using Fortis OS, I think you can. Otherwise it's some tape, I'm afraid.

    I've ordered a laptop PSU from ebay and will take your advice with regard to using the back switch as a 12V on/off. It will be generally be a spit/bodge and tape job but will see how it goes. I think there is now a market for repairing Tiviar PSU's ......if you are interested hs5424:D

    It's now 9.30 pm and just finished dinner so that tells you how busy I am. I have to try and get back to doing some workshop repairs. Maybe the next few days will
    suit as the weather forecast is bad. If I get a chance I will take a look at the Tiviar PSU's and see if something pops up. Probably ****ty chinese capacitors.

    I remember the early zgemma models of inferior build quality made in a back shed and was told to buy a better made box from Korea.

    Almost all TV's sold here in Ireland with the exception of LG, Samsung, and Sony come out of the Vestel factory in Turkey. Panasonic, Hitachi, Sanyo, Walker, Nordmende, Bush etc etc. A few years back I requested a schematic diagram for a Hitachi TV from the suppliers. When it arrived printed across the top was Vestel.
    Some of the phillips were a mixture of Phillips and Samsung panels. Now Phillips have a range of hotel TV's made in China. I picked up a new car battery recently and as the business owner carried it out to my van he told me to grab a label from the box beside them. There were labels that read Exide, Dagenam, Bosch, Yuasa, Continental etc etc. It's not as it appears out there.

    Hi, new to these types of boxes, if anyone has one can help?
    My menu button on remote is not bringing up an app screen (which should have access to settings) instead I get a very basic menu with 'info, timers, plugins, set-up, standby) When in epg, menu just brings up graphical changes
    My pause live TV doesn't work, and the manual I have downloaded says I need to open SETTINGS >CONFIGURATION and change then change something to auto for pause live TV. Well I can't, as my menu/box doesn't seem to have an app screen.
    When I'm epg, above the listing are 7 icons, one is a spanner, which could be a settings BUT I cannot work out on the remote how to get up there, up/down keys will only scroll listings!
    Where am I going wrong!?

    Post up what image is on box as might help also in determing if it needs to be reflashed to a newer version.

    I'm really not savvy with this, trying to learn fast. No idea what the image is? Quick look at thread, and I'm over my head. How do i determine or see what image I have. I could do with a tiviar for dummies book
