Kedves kollégák.
Szeretnék egy kamera jelet számítógép monitorra kötni.Érdekelne egy olyan kábel,
az egyik vége rca video és hang bemenet, a másik vége monitor csatlakozó.
Sziasztok!
Nem ledegradálni a kérdést :)
Igen ez egy régi kis 15 colos CRT moncsi :)
Bekapcs után olyan hangja van, mint egy laza vasmaggal rendelkezhő trafónak, emellett még egyéb hangokat is hallat :)
Mivel szeretek azért a lehetőségekhez mérten mindent rendbetenni így előbb megkérdem ez általában táphibás vagy sorkis pl?
Mert ha nagyon macerás akkor temrészetesen elbontom.
Csak tetszik a dög, mert két kis hangszórója van, hátul 3 jack aljzat, stb :)
Üdv:

This elderly monster arrived with the error “ 4 blinks “ which the manual suggest is a power board fault There are TWO power boards and a standby power board inside.
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained.
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ].
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out, I have done cold checks on both boards and there are no obvious differences.
The manual has only a block diagram of the power supply so it’s difficult to be sure of values / voltages.
My question is has anybody seen or worked one of these or similar beasts
Many thanks Ken

A készülék bemeneti jelforrás nélkül jól működik. A képernyőn jelzi: "check the signal cable".
Amint felismeri a jelforrást, eltűnik a kép, a háttérvilágítással együtt. Erre varrjon valaki gombot nekem :o)
"FONTOS! Olyan fórum téma nevet válassz, ami beszédes, minél pontosabban illeszkedik arra, amivel kapcsolatban írsz. Egy lehetséges jó elnevezés
pl: ORION LCD PT26S chassis 17MB12-2, a tápja nem indul
Az nem elég, hogy pl: "LG LCD-TV" vagy "HP laptop" és hasonlóak. Illetve érdektelen, nem releváns információt se tartalmazzon a cím!
A helytelenül elnevezett topik felfüggesztésre, majd 48 óra után törlésre kerül! Felfüggesztett állapotban nem tudnak mások addig hozzászólni, amíg ki nem javítod a címet.
A hibás cím utólagos javítása (48 órán belül) a "Szerkesztés" fülre kattintva végezhető el."
Ne indíts új topikot, a régi mellé. Várd ki türelemmel, amíg a feloldás megtörténik, ha már az első beírásnál figyelmetlen voltál. Legközelebb azonnali törlés mindkét topikra!
