Re: Problems with screen
This type of fault can be from the matrix decoder board that drives the display panel. It is also possible that the panel itself may have failed. There is a chance that there is a fault with one of the ribbon cable assemblies or one of the multi connector assemblies.
To answer your question, "YES" this type of service can be expensive. I would suggest to have an estimate done to see what the cost would be. Considering the continuous improvements in the technology, and the lowering of the prices it may be more feasible to replace the set. Most of the time, after a few years new replacement parts for these sets start to become scarce and their cost goes up.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch
christoph430. Your TV is hosed. Olevia will not fix it even if it is still under factory warranty. They are having lots of issues with their products and it will be too costly for them to pay for the repairs they should be covering. They are hoping you have an extended warranty through whomever you bought the TV from and will let that company deal with what should be THEIR problem. The repair company has to try to fix the TV at their cost. Nothing but a scam. We will never buy an Olevia TV again. Respond to email@example.com if you would like to understand details about our frustration with them. Unbelievable. Sorry for the bad news.
You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad
I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.
