Polaroid P43UP0117A - Odd lines on picture.
« on: August 15, 2019,12:03:13 »
Hi folks,

Bit of an odd one - Set is a Vestel using 17MB120 and 17IPS72  Wi-Fi and Bluetooth with a Vestel screen and LG T/con.

Problem - Two thin horizontal lines at the top of the screen. First thought 'panel' but the lines come and go every four seconds with any input. Didn't notice at first on picture 'till I used a signal with R,G and B - Showed up straight away on every primary colour, but hardly at all with a white screen.

To Ebay for SSB and T/con - Bit doubtful though, any thoughts  ? - Chris.

T/con and SSB from Ebay - Trouble persists. Thought go for the P/I as cheap.

Have a feeling that as all boards are so cheap on Ebay, maybe it's a known screen issue. This time can't blame Vestel metalwork and LG Leds.

Wonder who made the screen ? - Chris.

PS - P/I didn't help either, guess it's those chips on the flexies.
