Question about Sony KV-36XBR450 36" TV

Tv powers off after 11 to 15 minutes !

A technitian just replace the power supply and a voltage regulator, he left and then the tv will power off after 11 to 15 minutes of runing. I know it is not the timer, because the timer mode is off not activated. another thig is the colors are not the same on the left there is alot of green, middle ok, left side a lot of red, the guy said the tv has a built in system that would clear the colors automatically in 3 weeks . is that true ? thank you.

Re: tv powers off after 11 to 15 minutes !

He probably means the Deguassing coil, which is around the set. This is needed when the set is first turned on. Because of the earth polarized field, when you turn your set to the east, west or just a different degree, it affects the Deguassing area. This sometimes looks like a rainbow affect in your set, and sony's are bad about them. But all in all Sonys are good sets. If it does not go away it could be a problem with your picture tube, or the is a Magnet somewhere close by, like speaker or some type of big magnet. If so then remove Magnet and turn off and on until disappear. Is the pic good when running? Does the set comes right back up if you press power and wait another 11 to 15.?

My picture keeps on shrinking, rather than full tv screen each time I change the channel

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
Line to Load voltage regulation is absent. Your TVs' power supply regulator section circuit need a through check-up.

Check its main power supply regulator's output voltages. If main supply output from it is more than normal, this kind of fault can occur. [Over-voltage / Under-voltage] problem. The main system control IC in the TV will detect this condition, and will shut the TV Off. The best practice is to replace all the electrolytic capacitors at the main power supply regulator board.

The standby light flashes 7 times then pause and repeat.

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. Power supply regulator section circuit should be troubleshooted. It is fatal to proceed trouble shooting this section, without proper knowledge in electronics, as if you want to measure the voltages to this section, the TV must be switched ON. When it is switched ON, or powered up; most of the components in this section will be dangerous to touch. If you are not handy, seek tech support. It will be more better.

Thanks, this tv burn the diode r2m after 10 or 15 minutes in this lapse the tv works normal

Check the power supply switching regulator board [SMPS] for over output voltage that it meant to be.

Switch off it self,with error massege X RAY

The power supply regulator section of your JVC tv has got damaged. It outputs more voltage than normal to that is to be. There is so many reasons for that, including faulty capacitors and faulty regulators. Loose or bad solderings in the power supply section also may cause this type of fault. To retify it, just open your TV, and resolder all the suspected solder points in the power supply regulator section, by applying a little more soder. In most cases this will solve the problem. If not replace the power swithcing regulator device.
If you want anymore assistance, feel free to contact me throug Fixya. Ok.

The tv just won't come on!!

This is an indication that you have a problem on the power supply section or on the load because of the following reasons :

1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.

2. Over Current Protection - excessive load or faulty power supply cycling will

trigger the over current protection circuit.

3. High voltage - there might be an excessive high voltage or some other system detecting an out of regulation condition. However, in this case, there should be some indication that the deflection and HV is attempting to come up - momentary whine, static on the screen, etc.

4. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive or drop of voltage.

5. A problem with the microcontroller, relay or its driver, or standby power supply.

This is not DIY and quite technical so I

When I turn my KV-34XBR800 on, the picture will not come on and the standby light keeps on blinking 7 times each time.

Seven blinks of standby led in Sony sets denotes a High Voltage Shutdon proble. It is a self diagonosis process of the microcomputer Ic inside it, which senses the high voltage and shuts down the whole system to prevent it from further damages. The high voltage means that not the high line voltage of your househod supply, but the voltage inside the circuit board of the TV exceeds more than normal. Your tv, being 34", have a high tension voltage of 32,000VDC at the final anode of the picture tube. This voltage depends on the main regulated voltage goes into the circuit board from the power regulator system. There is a power regulator built sytem inside your TV, to regulate the voltage send to main board, which bears the Line Output Transformer [LOT], which in turn generated the above said high voltage. The normal regulated voltage going to board may be around 135VDC, to a 34" tv. Even a rise in, say, 2 voltage more than normal may cause high voltage to rise up considerably high enough to get it shut off. Soney sets are normally have STR regulated power supply system. It is very accurate and durable. The main fault comes to it is soldering trouble. The above said STR regulator may rise to as high as 90 degree centegrede when working. Repeted heating and cooling, make the soldering on its legs to get loose contacted; causing improper regulation process. Your tvs case must be so.
You just open your TV, and find out the regulator section inside it, where the AC input voltage goes into. Just pull it out and resolder all suspected points by applying a little more solder; as exact bad solder point is very difficult to locate. We in service field also does this. 90% sure that this will retify your problem.
Take proper care before opening your TV. Keep in mind that you are going to work with an electrical equipment, which have as high as 32,000VDC poins are inside it while working. Take all precautions. Keep children away from you while you works. Never allow them even stand beside you Ok.

TV red light blinks seven times. Is this a code for the problem?

Seven continous blinks of standby light in Sony TVs indiates that there is some problem in power regulator side or on horizontal output side. It is due to high voltage shutdown. When the [EHT] voltage ie Extra High Tension voltage given to the final anode of the picture tube exceeds 33KVDC [33,000VDC], this happens. The cause may be in the power regulation side in your TV. Normally Sony TVs are working at about 120 to 135VDC. If voltage at this DC rail exeeds, EHT said above will increase beyond its limit, and CPU Ic inside your TV will detect it and shuts the whole system down to prevent further damages to more components. This is happening in your TV now.
This process is called saftey shutdown.
To rectify this problem you have to open the TV. Proper care should be taken before opening it as you are going to work with an electrical equipment, which has very high voltage points are there inside. All precautions must be taken before opening the TV.
Normally this fault will be due to the poor regulation of the power supply section inside your TV, that causes a voltage higher than normal is comming into the main circuit from power supply. STR type regulatros are being used in Sony sets for this regulation purpose. You just locate the power regulation side, and check for any loose solderings to the legs of the STR regulator or its nearby components. You must have some concept of sodereing in this matter. Components fitted on the power supply section will heat up while TV works. Ater long use, the soldering at the legs of the heated components may get loose. We can't detect loose contact exactly where it is. So it is a good practice to resolder the sodering of suspected components, and we in practical servicing field also do this trick.
If it doesn't help, the STR fitted inside may faulty. Desolder it out from the board and go for a same type and number. Replacing it will solve the problem. Ok
