20 Most Recent Sony FD Trinitron WEGA KV-36FS120 36" TV - Page 6 Questions & Answers

It seems to be a problem to the power supply unit. I would suggest you have a look at the circuit board and look for capacitors that could have a popped up head. If you notice any, replacing it would solve your problem. I had the exact issue with my tv and fixed it that way. If you have any question please do not hesitate to ask, good luck.

check first fuse... then power supply

HelloSeven 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.Check the power supply section for any loose solderings. Resolder all suspected solder points by applying a little more solder, without making a solder bridge short in between close solder terminals. OK.

HelloWhen prompted for the code, enter the master reset code: 4357. This code will reset the master code.

i thought battery is gooing out of oder

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.

Hi,

From the symptoms you describe, it seems the high voltage flyback autotransformer has failed along with the horizontal amplifier (they are slaved to each other).

Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,

Since the set is new, it may be worth getting fixed up. If you decide to do so, call around, as shops have different rates and different expertise. Many shops are hurting for work because so many of the smaller sets are never repaired anymore; they are just thrown out and replaced since the cost of a new set is sometimes as low as the repair expense.

Hope that helps...Should you have any further questions, please feel free to post them here.

P.S. Before you assign a rating, please make sure that the issue is resolved or you are satisfied.

yes a bad fuse is the problem here or the power cord could be bad.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

Use a hair dryer on the back right side of unit. Humidity sensor may be causing the unit to stay off. The hair dryer may also remove dust causing a false humidity detection

Hello
After connecting the co-axial cable to its antenna socket, it must corl with it without any problem at all. Just connect it with external antenna and do auto tuning specifed according to its manual. Auto tuning function is decribed in page [17] of the user manual. When you do it, the set should tune automatically to all available channels at that time, and will store them in memory. Just wait till auto-tunig has been completed. At the end, it will stop tuning and will show the first channel programme that it got. Do this chek with antenna first. Then check with cable. Make sure that cable signals are analogue, and not digital. If it is digital, a converter box will be necessary to recieve cabel programmes. If it is analogue, all functions will go on as described earlier. OK.

Is your Model number that is printed on back of TV (KV-36FS120?)

this simply indicates a loosed component or connection inside
the tv set try resoldering the power supply section inside the unit or have a qualified tech for servicing

sometimes a leaking high voltage could caused this noise try to see it at a near dark room for arking

Thank you for your question.

 

Fortunately this is a common symptom and there is a fix for it.

 

There are two power supply IC's and a capacitor that need to be change. In particular IC6501, IC8002, part number, Mcz3001db, and C6556, 33uF @ 160V.

Hi, below are the list of Sony blinking codes


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 Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

FIVE Blinks---AKB circuit (AKB), 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. Also unit 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 IC406 audio amp, PS401 and 402.

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 (negative).

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, Vol 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 problem names is 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.

So, 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 4 times....This would tell you that you have no vertical and that is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault.

Hope it helped..

lose contact in cpt socket or in filament heater of crt,no high voltage, weak crt.

You have a bad MCZ. Try taking a blow dryer to the right side of the TV to see if this fixes the problem.

You will have to find these and replace them both on the board to the most left of the T.V. There are two of them. The one closest to the back of the T.V. is probably the problem.

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.

Few examples are given below; some of the issues may be resolved without the need for service. 1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set. 3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue. 4 blinks: - This indicates that there may be a back light or lamp power problem. 6 blinks: - This indicates that there is some kind of audio problem with your set. 7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced. 8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset: Try the following steps to check if the issue can be resolved. Turn off the television. Unplug the television power cord from the electrical outlet. Let the television remain without power for 60 seconds. Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.
