Sony KDL52VL150 CCFL LCD - lines in picture
Screenshots of problem here in the post.

Picture of screen with both cables to panel from TCON connected, and the other is with one side disconnected.

I have read the cables from the TCON to the display loosen up on the end to the panel. I believe as I am working on moving the cables around, the picture is improving 
and getting clearer. So I think thats the problem. Someone mentioned using tape over them to hold them to the panel better. I have not taken the metal frame off to 
look at them, but there is a narrow gap where I read some people stuff cardboard in there to press down on them better.

Has anyone ever seen this issue and come up with a good way to resecure the cables?

SonyKDL-32S2030 ki-be kapcsolgat.
SonyKDL-32S2030 ki-be kapcsolgat, majd néhány ki-be kapcsolgatás után végleg megáll. és hosszabb áramtalanítás után újra kezdi .A tápegység jónak látszik, már amennyire van időm méricskélni. Van valakinek ötlete? Kondikat cseréltem.
SONY KE-P37M1 működik, de kép/fény nincs.
Sziasztok! Ismét egy plazmával küzdök, ami még mindig nem tartozik kedvenceim közé. Működik a készülék, hang van, viszont a kijelző semmi életjelet nem mutat. Első megközelítésben minden feszültséget (tápegység) jónak mértem. Jobban lekövetve a dolgokat Y hibára akadtam. Konkrétan a lj41-02234b számú meghajtón nincs jelen a 15V. Az ezt előállító fokozat nem dolgozik. 5m0380r hajtaná a trafót, de itt nem teszi. A körben semmi hibás alkatrészt nem találtam. IC tápján 3V van jelen, ami (szerintem) kevés. Tapasztaltabb kollégáktól kérdezném, létezik, hogy az IC "emészti" fel a feszültséget? (nem melegszik, zárlatot nem mérek) Köszönettel: Kiss Z.
