My sony trinitron color tv model KV 27S65 ser.# 8012610. Takes awhile to come on. This has been happening for about 1 year. It works great good picture. Sound has deteriorated some. When I turn it on, it can takes between 5 & 10 minutes to come on. It blinks a few times in a lite red tint, and then everything is good. can you help me? Thanks Dale

This is a common problem with these TVs, it could be several things. The electrolytic capacitors could be worn out, and are taking longer to charge, or not taking a charge at all. If it is blinking, the picture tube may be going out as well. Fresh capacitors may bring it back to new, you may be able to get a local repairman to replace them if you are not comfortable with doing it.It could also be a loose solder joint on the bottom of the PCB (printed circuit board). Any solution to this problem will probably have to be performed by a tv repairman.

    The best way to find the bad caps if you do not have an ESR(equivalent series resistance) meter , is to just look for bulged or seeping capacitors. Although a lot of times the capacitor can fail without any visible signs. Sometimes the best bet (if you are feeling industrious) is to just replace all electrolytic capacitors over 100uf.

Sound problem comes from audio section,the power amplifier IC there is near to run out or crack or brittle ,cold solder joints of parts.
old solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the TV turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If this solution help you understand the problem :rate as fixya..

Good luck;

    Many of the later model Sony TV’s have a built in self-diagnosis
    function. If the timer/standby indicator is blinking, this could be an
    indication of a problem with the unit. The diagnostic blinking will
    occur automatically with no action required by you to engage it.
    timing of the blinking you see would be as follows: two to nine blinks,
    (depending on the fault), about a third of a second apart, then a pause
    for 3 seconds, then the two to nine blinks about a third of a second
    apart again.
    Here is a list of the problems that might have
    occurred indicated by the number of blinks. The words in parentheses
    are those, which you will see for each of these faults on a diagnosis
    screen described later in this article.

    • 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

    • 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 th

    Sony service trouble for the Audio error;

    C172 is a .47mfd
    used to decoupling the audio from IC101 the Variable audio control IC. This
    capacitor had 4.5 vdc on each leg measured to ground. Removing the capacitor
    and measuring the DC resistance across the cap measured 175 ohms. Replacement
    of the capacitor corrected the symptom.

If you are having some problems with your Sony Television, then this post is for you. Generally speaking, when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself. In some cases, you may be able to repair the television set yourself -- or in the worst case you may need to order parts, call a local repair shop to the have a repairman sent out, or even purchase a new television set.

First off, here are the list of codes and what they generally mean on my set (which applies to many recent model Sony Television sets. Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue. Here are the values of the various blinks.

* 0 times, Diagnosis: Power does not turn on. Possible causes include: Power cord is not plugged in, Fuse is burned out (F6001) (G board). Symptoms of the problem: Power does not come on, No power is supplied to the unit, AC power supply is faulty.
* 2 times, Diagnosis: B overcurrent (OCP). Possible causes: H. OUT (Q8024) is shorted. (D board), +B PWM (Q8035, 8038) is shorted. (D board) Symptoms of the problem: Power does not come on, Load on power line is shorted.
* 3 times, Diagnosis: +B overvoltage (OVP). Possible causes: IC501 is faulty (G board), IC5002 is faulty (G board). Symptoms of the problem: TV has entered standby mode.
* 4 times, Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.
* 5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
* 6 times, Diagnosis: LOW B OCP/OVP (Overcurrent/over voltage). Possible causes: +5 line is overloaded. (A, B boards), +5 line is shorted. (A, B boards). Symptoms of the problem: No picture.
* 7 times, Diagnosis: Horizontal deflection stopped. Possible cause: Q8035, 8038 is shorted. (D board)
* 8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)
* 9 times, Diagnosis: Audio error. Possible causes: +- 19V line is shorted. (A, B boards), IC708 is faulty. (A board), PS701 or PS702 is opened. (A board). Symptoms of the problem: No sound

    Certainly, I can help you. I would recommend going to the following link and getting the service manual so he can see first hand disassembly instructions and testing proceedures. Its only 10.99 and they email it to you shortly after purchase. The manual is a valuable resource as it will have part numbers in case you do need a new KD board. heres the link.

    The steady blinking light means there is no specific code. the double-side board (the one lying flat/horizontal just to the right of the vertical power supply board which has the fuses) has a burnt transistor (the one with the sizable heat sink on it, at the back left corner when looking at the board from the rear of the TV). It is blowing the (non-power supply) fuse.

My remote worked fine, but suddenly won't work at all. TV is older Sony Wega 24" Trinitron (KV-24FS100). The satellite remote will change the channels, cause it's using the box, but it won't control...

Could be the IR receiver in the TV.
Make sure nothing is in front of the TV that would block the IR from receiving commands from the remote, I've seen customers put VHS tapes on the front of their TV that caused the remote to not to work.

Good luck

Sony Trinitron---Blinks 9 times, won't come on!

A specific model number will probably get you more specific
help.. but if you check around the internet by model number
you will likely be presented with some SERIOUS PART opportunities...

The FASHING LIGHT means you have a hard fault in the power circuits...

The number of flashes is mean to point you to a specific area...

I gave all my big flat screens away in favor of the new
HD stuff... (certainly less reliable than those Sony sers...

Sony FD Trinitron WEGA KV-24FS120 24" TV Color changes

Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
