sony 21 ctv m#kvxa21n93 s#1001619 continous blink

[delio]

gud day mga sis @ master patulong nman sa ginagawa ko na sony na continous blink,,,una nya sira ay 2 blinks ang ginawa ko ay nagpalit ako ng reg. str f6654 @ 1 ohm res. sa b+ path, h-out d2578, nagkaron ng b+ pro di oscillate at unti unti bumabagsak ang b+, ngayon ay continous blink na at wala na b+, ano kaya posible sira non? thanx in advance sa mga sis @ master

hung muna sis ang HOT, at try change B+ Cap. at measure ang B+ kung Mag stable na.

   Sony Blink Codes:

 Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
    Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
    One blink - not used for the self-diagnosis
    Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
    Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
    Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
    Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
    Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
    Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

    Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.


    Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).

    Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Intermittent problems? This is a great feature. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.

Now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking four times. This would tell you that you have no vertical sweep, which is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure..

IMPORTANT: After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.

mga sis @ master regarding pa din sa sony na gawa ko hindi ko nasabi na ung continous blink ay may kasama na tik sound ng relay...thanx,,,

Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.

check jungle IC301, search mo datasheet. hanapin mo VCC pin check mo kung tama voltage according sa datasheet, hanapin mo rin  yung ground or better yet resolder mo lahat ng pins ng jungle and other major components ng tv mo.

Pasub muna....

mga sis at master regarding p din sa ginagawa ko na sony ang status ng unit ay continous blink w/ tik tik sound ng relay wala din sec. voltage at sinisibak ang 0.1 ohm 1 w res. n naka parallel sa primary filter ecaps na 330uf 450v, sub ko ng res. kanina at hang ko ang reg. baka sakali mawala ang tik tik sound pro ganon pa  din, mga master @ sis ask ko lang ano kaya posible sira nito sana matulungan nyo ko ano kaya ang dahilan bakit wala boltahe sa primary kahit sub na ko ng reg. at tanong ko na din kung tama ang ginagawa ko na mag hang ng reg.,,,thanx sa lahat....

di hinahang yung regulator. ito ba strf6654(IC 601)? ang saya andami components nito model mo. pag bukas mo ng tv 2 blinks ang code.

check mo ito:

HOT Q511 is shorted.

IC700 is shorted (C1 board)  

walang -13V (A board)

IC 503 faulty (A board)

di bale baka mas mahal singil mo dito.

mga master sa sony patulong naman sa ginagawa ko na sony na continous blink at may tik tik sound ng relay, nagpalit na ako ng reg. ic pro wala pa din sec.voltage, ano po kaya posible sira,,,pag on ng unit tik tik lang wla b+....thanx in advance....

[J@M]

CHeck mo nb linya ng B+ nyan, diode,transistor hangga makarating ka ng HOT....or mas maganda tanggalin mo muna HOT din sukat sa B+ kung meron na...

mga sis, master gud day sanyo, pde ba ako makahingi ng datasheet ng ginagawa ko na sony,,,dis is my email add. deltopz08@yahoo.com, til now di ko pa din maayos,,,tahnx sa lahat

Sony KV-XA21N93

datasheet? eh di i-google mo na lang.
