PC-ul meu

Default Problema Panasonic VT20 50"

Salut

Am un Panasonic VT20 de 50" care a inceput acum 2 ani sa afiseze sporadic niste dungulite rosii in partea stanga. Apareau si dispareau. Se pot sesiza si in poze. Erau restranse in partea stanga pe o latime de aproximativ 2cm.

In ultima perioada aceste dungulite s-au extins, tot in partea stanga sunt dar sunt vizibile pe o latime deja de 10cm, sunt permanente, nu mai dispar. Se manifesta si pe PC si pe PS4.

Am incercuit zonele in care se vad aceste dungulite, chiar daca in poza respectiva nu se vad atat de bine.
Nu le-am putut prinde foarte bine in poze, cu ochiul liber se vad mult mai clar.

Ce ar putea fi? S-ar putea remedia defectiunea sau este pe duca si trebuie sa ma gandesc la alt display?

Incearca alt cablu de semnal, asa am patit eu pe un port HDMI, si era cablul cu probleme.

Incearca si alte conexiuni (alte mufe)

Am scris in postul original ca problema se manifesta atat pe PC cat si pe PS4, deci e vorba de 2 porturi HDMI si de 2 cabluri diferite.

OK, acum ai lamurit, initial se putea intelege si ca jonglezi cele 2 surse pe o intrare.

Pune un stick cu un screenshot și vezi dacă imaginea de pe stick tot așa o afișează. Măcar să elimini cablul/mufa hdmi din ecuație.

Slabe sanse, dar incearca si asta.

Display-ul este legat de partea electronica prin niste banzi flexibilee (maro) care sunt lipite, probabil acele lipituri s-au desfacut, uneori este sufivcient sa pui un burete sa preseze pe lipituri (intre rama televizorului si banda), sau trebuie refacute. Daca te pricepi poti desface monitorul (doar rama din spate trebuie data jos), dupa care pornesti tv-ul si incepi sa apesi cu degetul pe benzi, asa afli unde este lipitura rece, acolo pui un burete sa preseze pe aceasta.

Eu am o plasma G30...genul acela de artefacte imi face daca afisez o imagine cu albastru intens...dupaia raman aprinsi pixelii in rosu si isi revine destul de greu dar isi revine. Cred ca au obosit pixelii mai in gluma in serios.
