Question about RCA E13345 13" TV

2 Answers

RCA Chassis TX808D, No High Voltage.

I've checked the high voltage circuit, pin 29 of Jungle Ic does not go over 3.2V. I also checked pin26, the HVcc. The voltage goes to about 7v then shuts off. I desolded pin 26 and voltage does same thing.  I've checked the 9v regulator, seems like its working when I compared it to another unit.  What I did notice is when unit is plugged in without pressing the power button, I hear a slight buzzing sound from the power supply. The working unit does not buzz. I believe unit was hit by lightning. Any help is appreciated.

Thanks Jimmy

    Horizontal Output is good. I've checked several diodes and zener diodes. Can't seem to find anything shorted.

12 Volt regulator circuit usual culprit......replace
1) TP 15 = 198752 sub 185197 sub generic
2) DP02 = SK12A 12v zener  

solder any bad connects.....T.

Did you check the horizontal output? then check all zener diode at the hotside! can you give me the number of all power regulator at the hot and cold area!?

Toshiba 24af45 horizontal


If rolling in a right to left and not up down it is a sync problem--horizontal sync comes from one of two places in general---a pulse off the high voltage transformer or directly off of what is called in the trade the Jungle IC.

That is not a joke--Most of these sets use a large IC (63 pins or more not unusual) that contains: color, video, vertical drive, ABL and much more---so much is crammed into that chip it decades ago was named the Jungle for clear reasons.

A schematic and or scope may be needed to trace and find what is bad.

if off the high voltage transformer (more common in old sets than new ones) it will be a open resistor.

If at the jungle you would have to go to the pin with the sync and follow it out to see if none at source or if lost somewhere down the stream.

Sony KV-27HFR TV, no picture no sound; but got HV


The high voltage transformer may be the problem, because it feeds back secondary voltages to different parts of the set, for example is the vertical deflection voltage present at the ic, if memory serves me there should be around 26volts, if it's missing it means the fuse is open or the flyback pin is not generating the voltage.

RED FLASH AND TV URNS OFF


  • 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 IC406audio 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.

My sony trinitron will NOT turn ON, and blinking standby light is constantly blinking... what is the common problem with this?


If you let us know how many times the light blinks, that will let us know whereabouts the fault area lies. Her is the list. I hope it is helpfull.

I have a Sony kv-40xbr800. The standby light flashes 6-7 times and does not turn on. If left off for a couple of day, it may turn on. Is there an easy fix?


SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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.

Flashing red light


The jungle chip is the main IC processor. It is very complicated and has hundreds of circuits surrounding its complexity.

Six blinks is a diagnostic code for loss of horizontal sweep. Thus there is no raster and no high voltage.

Cure requires a look at the jungle chip and the horizontal synch signal to see where it got lost. Cost of repair is not so much unless the jungle chip must be replaced which is rare, but very expensive.

A good repair place can fix it quickly and under $100 so beware of who works on it.

Model CF1926A TV with insufficient vertical height. I replaced c308, c305, c301, c315. voltage was missing from ic501, pin 29; restored with replacement of c301. no help to vertical. voltage was missing...


I think you missed one cap. Look for another 1ufd cap close to the jungle chip. It will have the circuit designation in the 300's like the others in the vertical circuit. It is just not located close by. I think that one will fix it.I don't have the service data with me so I can't give you the exact designation.
