My TV picture is very wavy and has vertical lines that flicker quite a bit. It's far to bad to actually watch something like this. I've tested out all of the inputs and they all give the same result. The audio works just fine. The on screen display also works just fine. It also turns on and off and seems to perform all other functions just fine. If somebody could point me in the right direction, I'd like to get this TV working again. Thanks I have the same wavy lines. tv repair shop said its the hyper scan board. TV shop wants $425 on top of the $75 I just gave them to diagnose the problem.
The Hyper board is located under a plastic part that holds it in place so you won't short out your whole circuit board,you must unplug the set and don't plug it back in until your new hyper is installed and LOCKED DOWN with the protective plastic cover.The cover is held in place by 4 screws,2 on either side of it.The exact location of the hyper is behind the green circuit board just behind where all your cords plug in,composite cable and sound cable etc.Once you remove the plastic cover you simply lift the hyper straight up and out of the tv.Then you push the new or repaired hyper straight down into the board,their are 2 tiny pieces of metal on each end of the hyper board and they shoud line it up as you push it into place.DO NOT POWER UP until the plastic holder is firmly screwed into place or you will short circuit your convergence board and it is expensive to repair and definetly not for begginers to mess with.If you do exactly as suggested you will sucessfully be able to fix the hyper without a problem.
I think if the picture is wavy like below mentioned images then its problem of Hyper scan Board and it requires replacement / repair on component level.
Hyper board needs a lot repair work and you should ask for discount in repair cost.
The tv shop is ver correct of this problem.
as u your self can get the part from
www.partstore.com
just insert your model number and brand and get the require parts.
Hi and welcome to FixYa,
Initially, it could be something else such as a leaky capacitor in the power supply board, or any of the filter capacitors in any of the +B supplies.
This of course would require opening the unit, perform voltage measurements, determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you however be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
In some instances it could be electrical interference from nearby other devices. Workarounds would include moving said devices away, trying the TV using another outlet, clearing the cables and AC cords at the rear of the TV, removing connectors/cables at the back one at a time and see if any do cause the wavy lines.
Good luck and Thank you for using FixYa.
Your TV needs repair because there is some problem with the display IC.
This could be an aerial problem, do you have Pick-ups? they help to pick up channels and signals in the area.
It could also be something else like the Scan Board, I'm pretty sure you can pick one of these on the internet for a cheap price. but get someone else to install it for you.
If it is still under warranty, take it back to the shop you bought it from as they will happily replace it for you.
Hope this is your FixYa! -P3NGYJ03
