Mam na stole tento DVD prehravac. Udajne bolo tocene trimrami na laseri (su tam 2x). DVD po cca 10s skumani nenajde, ale CD funguje. Da sa este nieco vymysliet nastavenim, alebo rovno ten laser vymenit?

proc bylo s tema trimrama rychtovano?
sice o laserech vim ho..., ale nez bych sahl po vymene tak bych napred skusil trochu postelovat s teme trimrama jestli se to ujme. CD maji sirsi stopu takze mensi rozostreni jim narozdil od DVD nevadi

Ze vraj dochadzalo k zlemu citaniu medii,tak to bol pokus na odstranenie. Pokusil som sa trafit na odhad, a podarilo sa to dostat do fazy najdenia disku, dostal som sa do menu ale samotny film seklo s hlaskou "disc error".
Ak sa mi to nepodari najst skusim to riesit vymenou celeho laseru. Alebo?

ak sa ti to nepodari nastavit tak uz len vimenit u DVD je to zabavacka nastavit laser este som tio nerobil,ale prave na tomto fore som otom cital

takze misto toho aby nekdo si vycistil cocku tak radsi rozsteluje optiku mozna ze je to blbost ale co zkusit nak k tomu trimru prilipnout multimetru a nastelovat to podle voltu co pujdou pres ten trimr akorat nevim kolik tam ma jit voltiku.

wiktor: u kazde hlavy to nejspis budou jiny hodnoty napeti. proč by tam jinak byly ty trimry a ne pevny rezistory? (muj nazor)

ypsi: pri cene laseru bych radsi skousel vrtat s trimrama a trefit to

Ludia su koumaci. Akonahle sa s niecim tocit da, tak preco to neskusit?

Nasiel som nejaky datasheet k tomuto laseru s tymito hodnotami:
Tracking Sensitivity 0.82mm/V(at 5Hz)
Tracking Resonance Frequency 50Hz
Focusing Sensitivity 1.20mm/V(at 5Hz)
Focusing Resonance Frequency 46Hz
RF Signal
DVD 1.00Vp-p
CD 1.00Vp-p
Tracking Error Signal
DVD 2.40Vp-p
CD 0.14Vp-p
Focusing Error Signal
DVD 0.70Vp-p
CD 0.59Vp-p
Dimensions 51.5(D) 37.4(W) 17.1(H)mm
Weight 17g
FEATURES
1. This is a simple optical system with a 1can 2-wavelength LD that at the same time provides high
performance.
2. Although the design is simple, the high playability actuator ensures high precision.
3. The size of the pick-up makes it adaptable to a variety of drive configurations.
4. Tracking error signal detection: DVD: 1-beam method, CD: 3-beam method
5. Astigmatic method used for focus error signal detection.
USES
DVD Player drivers.

Len neviem od cohosa odrazit,resp. ktore napatia su smerodatne....

nic o nastaveni tam nevidim. jen co z toho leze. kdes nasel ten datasheet?
pripadne posli na flick.007@seznam.cz

flick007: Nahodou kdesi na nete, mas ho v maili.

Takze cena toho laseru je 650Sk + DPH. Teraz mam dilemu ci to riesit alebo kupit cely player...

skus poslat email nejakymu dvd servisu a zeptat se jak se serizuje laser nebo jestli se to da nejak udelat doma

a vis jiste ze kdyz koupis novej ze bude serizenej? co kdyz ho budes muset taky seridit

Ved prave....
