Xav tau lub TV tab sis tsuas yog muaj lub monitor qub? Lossis koj puas xav txuag nyiaj ntawm kev yuav TV rau chav ua noj, tsheb lossis chaw nres tsheb? Peb paub yuav pab koj li cas hauv cov xwm txheej no.

Nyob rau hauv ib tug classic Lavxias teb sab chav tsev, lub TV yog lub taub hau ntawm txhua yam. Nws feem ntau yog ntsia rau hauv txhua chav. Feem ntau, ib qho screen ntxiv yuav tsis raug mob, tshwj xeeb tshaj yog tias nws twb nyob rau hauv daim ntawv ntawm lub qub LCD saib.

Muaj ob peb txoj hauv kev los siv lub monitor ua TV. Koj tuaj yeem yuav lub thawv teeb saum toj, hais, Roku. Koj tuaj yeem nce koj cov peev nyiaj me ntsis thiab txuas lub khoos phis tawj mini, xws li Raspberry Pi, rau tus phooj ywg qub. Tab sis muaj ntau txoj kev radical, zoo ib yam li tig lub boombox rau hauv mp3 player.

Yuav luag txhua lub LCD saib muaj qhov I / O interface hu ua. Yog tias koj tshem lub hau ntawm lub monitor thiab nkag mus rau sab hauv, koj tuaj yeem pom tias cov connectors nyob rau ntawm ib lub rooj tsavxwm. Ntxiv nrog rau lwm yam khoom, lub rooj tsavxwm no txuas nrog lub ribbon hloov tau yooj yim, zoo ib yam li IDE rau hard drives.

Txhawm rau txhim kho tus saib, koj yuav tsum tau yuav daim npav nthuav dav rau qhov kev sib txuas no uas muaj lub tshuab txiav tawm video built-in. Cov khoom siv zoo li no tuaj yeem yuav, piv txwv li, lossis. Lub decoder thiab nws cov zis yuav ua rau nws muaj peev xwm mus ua si analog (thiab nyob rau hauv cov ntaub ntawv ntawm ib tug ntau tshaj board - thiab) TV ncaj qha, tsis siv ntau yam ntawm set-top thawv thiab txawm lub computer.

TTX boards:

• Qhov ntau zaus yog 48, 25-863, 25 MHz.
• Xim system - PAL / SECAM / NTSC.
• Suab system - B / G, D / K, l, M / N, NICAM / A2, BTSC.
• Tus naj npawb ntawm cov channel yog 200.
• Teletext - 10 nplooj ntawv (chip 39 - 10 nplooj ntawv, nti 59 - 1000 nplooj ntawv).
• Video teeb liab input hom (VGA, HDMI) - mus txog 1920 × 1080 @ 60 Hz.
• Txhawb video daws teeb meem - 480i, 480p, 576i, 576p, 720p, 1080i, 1080p.
• Suab amplifier tso zis zog - 2 × 2, 3 W (40) 1 HD + N <10% @ 1 KHz.
• Cov khoom siv hluav taws xob - 12 V.

Input connectors:

• Lub hwj chim - 12 V.
• VGA input.
• HDMI input.
• Composite video thiab stereo audio input.
• Suab input thaum siv lub TV ua lub computer saib.
• Lub mloog pob ntseg tso zis.
• USB input (rau firmware hloov tshiab).
• Kav hlau txais xov los yog cable input.

Qhov tseeb, txoj hauv kev yooj yim tshaj plaws xaus ntawm no: lub rooj tsav xwm yuav thiab saib tau raug xa mus rau cov khoom siv kho suab-video. Tom qab ib ntus, tom qab them me me, koj muaj TV tshiab hauv koj txhais tes. Txhua yam uas tseem tshuav yog nruab nws thiab txuas lub kav hlau txais xov lossis cable TV xaim.

Ib txoj hauv kev yooj yim me ntsis ntawm kev teeb tsa tus kheej tau piav qhia meej los ntawm cov npoj yaig ntawm cov peev txheej Mysku.ru. Cia peb xav txog luv luv.

1. Thawj kauj ruam yog tshem tawm lub nraub qaum ntawm lub monitor.
2. Nrhiav qhov tsim nyog expansion board thiab dismantle nws - disconnect nws los ntawm lub voj. Nco ntsoov! Nws yog ib qho tsim nyog yuav tsum rhuav tshem nws nrog kev saib xyuas zoo tshaj plaws: lub tsheb ciav hlau yuav tsum tsis ua haujlwm txawm tias qhov khoov tsis tiav.
3. Nyob rau tib lub sijhawm, koj tuaj yeem txiav txim siab qhov cim ntawm lub matrix thiab pom cov firmware ntawm nws, nrog rau txiav txim siab cov khoom siv hluav taws xob.
4. Tom qab ntawd koj yuav tsum txuas lub rooj tsavxwm tshiab. Muaj ob txoj kev xaiv: xaj kom haum cable los ntawm Suav lossis solder nws. Qhov thib ob txheej txheem yog ntev, tedious, tab sis rau ib tug uas muaj ib tug soldering hlau, tsis muaj dab tsi yog tsis yooj yim sua. Nws yog pheej yig dua thiab sai dua li no. Hmoov tsis zoo, koj yuav tsum nrhiav tus pinout rau txhua tus qauv tshwj xeeb.
5. Tom qab ntawd, koj yuav tau txiav txim siab txog kev hloov kho rau rooj plaub. Qhov tshiab, vim tias muaj cov khoom tsim hauv lub tshuab txiav txim siab rau analog thiab / lossis digital TV, yuav loj dua li yav dhau los. Tsis tas li ntawd, koj yuav tau ua qhov ntxiv rau hauv rooj plaub kom coj tawm cov khoom sib txuas tshiab.
6. Tom qab kev teeb tsa, koj yuav tsum txiav txim siab txog qhov voltage uas lub rooj tsavxwm yuav muab rau lub matrix, thiab teem nws siv lub jumper (saib cov lus qhia rau cov khoom yuav khoom).
7. Lub rooj tsavxwm tau txais lub zog los ntawm kev siv hluav taws xob sab nraud. 12 V yuav tsum tau - qhov no yog qhov voltage yuav tsum tau rau kev ua hauj lwm ntawm lub monitor filling. Yog li, yog tias koj xav tau, koj tuaj yeem siv hluav taws xob los ntawm lub rooj tsavxwm thiab tshem tawm cov xov hlau tsis tsim nyog.

8. Ib lub rooj tsavxwm yuav los kho dua tshiab feem ntau suav nrog tus txais infrared (lossis qhov kev xaiv ua kom tiav) thiab cov chaw taws teeb tswj. Hauv cov qauv pheej yig tshaj plaws, koj yuav tsum tau saib xyuas kev nqa tus txais mus rau lub vaj huam sib luag pem hauv ntej ntawm lub cuab yeej lossis txawm mus rau lub khw muag khoom ze rau nws. Lub receiver tuaj yeem txuas nrog cov ntawv kim dua ntawm qhov chaw nres nkoj sab nraud, zoo li cov ntaub ntawv qub PCI TV tuners. Qhov kev xaiv no tsis xav tau kev txiav tawm ntxiv thiab tuaj yeem muab tso rau txhua qhov chaw.

   

9. Tom qab kev teeb tsa, koj tuaj yeem qhib lub TV tshiab thiab teeb tsa raws li cov lus qhia. Yog tias Suav mam li xa cov lus qhia ua lawv hom lus, nws tsim nyog hu rau Runet. Hmoov zoo, tag nrho cov qauv tseem ceeb ntawm cov khoom siv no twb tau txiav txim siab ntau dua ib zaug hauv nws qhov chaw qhib.
10. Cia peb siv nws!

Txawm hais tias muaj teeb meem tshwm sim nrog kev teeb tsa thiab teeb tsa, xws li kev txhim kho kev saib xyuas yog qhov ncaj ncees. Ntau tus muaj cov khoom qub, tsis tau lees paub 17- thiab 19-nti. Tus nqi ntawm cov khoom siv zoo li no hauv kev ua lag luam theem nrab yog qhov qis heev, thiab cov duab zoo feem ntau tsis phem dua li TV tshiab. Nws hloov tawm lub TV zoo tshaj plaws rau chav ua noj, chav me lossis lub tsev me me rau lub caij ntuj sov rau tus nqi tsawg - los ntawm 15 txog 60 las, nyob ntawm qhov kev teeb tsa thiab kev ua haujlwm.
