Hello my television is a sony KV32HX15U , when I switch it on the picture takes about 10 seconds to display the television then stays on for about 20 minutes then switches off into stand by mode and there is no stand by light on and no flashing light. Are you able to help.

The diagnostic code result is as follows.
E11 : 8v (0,225) 5
E09 : tuner (0,225) 1
.
Regards The diagnostic code result is as follows. E11 : 8v (0,225) 5 E09 : tuner (0,225) 1 . Regards

Thanks for the response.

E11 (8Volts supply to jungle IC) error code had most number of times detected by the processor that is gone to malfunction and followed by E09 (no tuner has been detected).

I believe that the E11 is the origin of the fault that is linked by the fault E09 which is related to each other because if the 8Volts supply line is faulty the tendency of the 5volts supply line for the tuner will gone bad also.

This kind of fault needs to have an skill of an expert to resolve the issue.
The following parts most likely to be faulty and needs to checked using the multimeter.

1. Electrolytic capacitor (C631,1000uf/25V

2. 8Volts Regulator IC (IC603)

3. Electrolytic capacitor (C610, 470uf/16V)

4. Zener diode (D615)

5. 5volts regulator IC (IC604)

6. Electrolytic capacitor (C605, 470uf/16V)

7. Zener diode (D600)


The parts above must be checked to determine where the fault came from. Bad solder joints must be isolated also. Cracked, cold, dried solder is very common because of aging, heat build up upon operation. This is hard to spot, magnifying glass is needed to see them on the board.

This is fixable, suspected faulty parts is widely available at electronics store and not expensive.

If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to ask for an assistance of a qualified TV Technician.

Please let me know if you need further assistance.

Ratings and feedback is highly appreciated.

Have a nice day! Thanks for the response.

I have a multimeter and esr capacitance meter also I have a intrest in electronics so I would like to test the suspected faulty parts myself.

Ok mate, since you have necessary test instruments, check the parts I've mentioned above. Check also bad solder joints on the jungle IC (IC201) this is a rectangular 64 pin IC, this is prone for bad solder joints because its heat up upon operation. Resolder the joints as much as possible but make sure that you will not short the leads. Please use pointed soldering iron (30w only).

I have tested some components results are for capacitors they were tested in circuit.

1. Electrolytic capacitor (C631,1000uf/25V ) result 1200uf / ESR 0.08
2.
3  Electrolytic capacitor (C610, 470uf/16V) result ? / ESR 0.18
4.
5.
6. Electrolytic capacitor (C605, 470uf/16V) result ? / ESR 0.13

The last two capacitors will have to be removed to get a capacitance reading so I am checking the components as they a listed in numerical order also there dose not seem to be any bad solder.

How do I test the item no (2). 8Volts Regulator IC (IC603) please state in circuit test and removed from circuit test.

Thanks

Resistance check on 8 and 5 volts regulator is not the best way to test its condition because based on my experienced there's a variable resistance reading when it is brand new and used in the circuit.

I would advice you to check the input voltage reading on pin no. 1 both IC603 and IC604. They have common input voltage, at least higher than 10volts.


Output voltage on pin no. 2 should be a regulated 8volts (IC603)

Output voltage on pin no. 2 should be a regulated 8volts (IC604)

Pin no. 3 of IC603 and IC604 (middle pin) is a common ground.

Please let me know the voltage reading on these part to continue our diagnosis.

Be patient, 8 and 5 volts line splits to different parts, series of test will be done.

Note : while testing on the voltages, make sure that you will not short the leads of your multimeter to other pin to avoid further damaged (short circuit)

Put the black test prod of your multimeter on the chassis ground while on testing. Grounded wire around the picture tube is one of the best chassis ground.

7. Zener diode (D600) Have found D600 no component or holes in board


Capacitors have been removed checked and re soldered back in.
Regulators have had the solder heated up and then set
I cannot find the zener diodes check to see if there on board .

The television still switches on the sound can be heard then the picture takes about 10 seconds to display but still switches off after 20 minutes

You are getting the right input and output voltage from the 8 volts regulator IC, it means that 1-7 parts are in good condition.

May you please clear the data on the self diagnostic screen by pressing "80" while on the self dianostic mode to ensure we get the right error code.

Check again the self diagnostic screen once the unit gone to shutdown after a few minutes and then let me know the result.

I have a suspected parts which is gone bad on this kind of symptoms but I want to make sure that it is supported by the self diagnostic result before to advice you which parts are going to replaced.

Hi jdvillanueva

I have cleared the self diagnostic data , I have checked the self diagnostic screen again and it shows no fault.
So no fault detected by self diagnostic.

May I know if the unit gone to subsequent shutdown before you check the self diagnostic screen, if not, please wait until the set shutdown and then check it again.

Hi jdvillanueva

I reset data then turned off television then turned on television checked that data was reset. Then turned off television again then turned on television again and left it to switch off its self which it did and then I checked self diagnostic screen {no fault detected by self diagnostic)

Since there's no error detected through self diagnostic screen, the fault is on the low voltage power supply board (voltage regulator circuitry). I would advice you to replaced IC601 MCZ3001D part no. 8-759-670-30 (http://www.ebay.com/itm/MCZ3001DB-SOCKET... . Also check for bad solder joints and the ESR value of electrolytic capacitor on that section C607, C608, C618, C637, C638, C640 Since there's no error detected through self diagnostic screen, the fault is on the low voltage power supply board (voltage regulator circuitry).

The capacitors are within ESR values (good condition). Please replaced IC601, Q606 and Q607. You may not replaced Q606 and Q607 if they are almost identical on resistance reading.
