Starts and then stops, LED flashes 13 times | Substituir d802 (rpg10) e r854 (0,47Ω) | ||
| SONY |
KV-25R2E
|
The "bu" burns and the LED flashes twice | Change the "bu" and solder the t531, horizontal driver transformer | ||
| SONY |
KV29FC20E
|
Has sound. Sometimes it blocks the video. Shaking the chassis cannot reach a conclusion. | Resolder ic301 cxa21140s, although nothing is noticeable | ||

KV-M21_ _ CHASSI BE2A
|
Starting color ok. after 3 to 4 min. blinks and disappears | Tda8304 | ||
| SONY |
CHASSI BE5E
|
Does not work, LED blinks 4x. eliminating protection (pin 1 from up to ground) and forcing on condition (base shunt with q603 emitter), it starts horizontal and vertical but without control. | Cpu | ||
| SONY |
KV-28WX1E
|
Very high power supply, 180v instead of 120v, and the d611 immediately burns out | R606 -- 68Ω, interrupted | ||
| SONY |
KV-M2100
|
Color failure | Trimer ct332 30pf, replace with another model, the original one is fake | ||
| SONY |
CHASSIS AE1C
|
When turned on, it is on channel 59 and the volume is at maximum. When pressing the p+ key it goes to channel 00 but immediately returns to 59. | Replace a eeprom (ic005). | ||
| SONY |
CHASSIS AE1C
|
East-west damage and/or excessive height. | Ic tea2031a (on j board) and sometimes coil l806 on main board. | ||
| SONY |
CHASSIS BE-2A
|
Distorted image in the central area of the screen, concavities on the sides, east/west does not react to adjustments | The fault is located in the pin-out circuit (ic801 ba4558), it is difficult to explain the symptoms of this fault. pin 1 of ic801 had 10v, pin 3 had 0.6v, base of transistor q803 0.6v. Looking at the diagram you can see wsound the errors are, the cause is r809 of 3 | ||
| SONY |
KV-M2100E CHASSIS BE-2A
|
"pin amp" and "h-size" do not work correctly, cannot be adjusted. | See the following components: c807 1nf/ 2kv c806 47nf/250v, lastly ic 502 tda8304. | ||

| SONY |
KV-14TE1 CHASSIS BE-4
|
Does not turn on, the LED flashes 6 times | According to the service manual, 6 flash corresponds to "overvoltage / overcurrent protection (pin 52) high", pin 52 of the processor has 5v when it should have 100mv, the protection circuit is armed. in this case it was due to a short circuit in the line transformer | ||
| SONY |
KV-DX21TD CH.AE1
|
Sometimes the vertical shrinks by 10 cm at the bottom and top | During manufacturing, the solder caught one of the r1517 pins, leaving the island with the copper visible (board j1) | ||
| SONY |
KV-28FX65E
|
Green and red horizontal bars appear | Ic tda-6111q (red cathode) on the kinescope board | ||
