These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

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.

HI,
ur tv has problem with its vertical scanning side. vertical scanning output ic (integrated circuit ) may have some problem ( faulty or dry soldering in its leads). u can easily find out the vertical ic on ur tv. there will be four wire coming from the coil which is fitted on the picture tube neck, of which 2 will goto horizontal scanning section and the remaining two will go to vertical scanning section. just follow the two thin wire (normally in color green and yellow ). it will goto a socket on the main board. follow the track on the board. it will lead u to vertical scanning section. check for any dry soldering, if not , replace the ic.
ok

Your vertical IC will need resoldering. If you can take this board out and inspect the pins under the vertical IC, you will see rings around the IC. This is a common problem for you model of TV. Hope this helps...show a few hands of support.

The ghost image you are seeing is known as Screen burn-in. CRT tvs and more commonly plasmas are susceptible to this fault. Only solution is to replace the CRT which is usually not cost effective.

In the menu, select "Channel Set Up", then set the "Cable" option to OFF. Finally, run "Auto Program" to find all available channels. Done.

Hi this fault due to a capacitor in the frame (field) output stage going low value / the one to look for is a 680uf 63v ( might be 50v) it is mounted to the right of the frame out put ic.Hope this will help regards, windyhouse.

Unplug the unit and try to open the back cover and check the power supply section for any busted fuse. Replace it with the same amperage value .

Hello
There are few models of Sony telivisions which uses transistors in vertical output section. It will be a matched pair of PNP and NPN transistors. According to Sony schematic which I have with me used 2SB6494(PNP) AND 2SD669A(NPN) as vertical outputs and 2SC2383 as vertical drive, 2SC1364 as vertical oscillator. Just try to get the orginal numbers or find its equivalents from data book. Ok.

Most shops have a unit made by B&K for testing recharging crts.

We call it hitting a tube, but most of the time if it works it will last less than a year.

I have done it many times with customer approval and the results can be dramatic.

Considering the age of this set you may just want to let it go.....

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

check for any cold solder on the high voltage section of your tv A high voltage section is located at the power supply section, this is where the power cord is connected.resolder them,the horizontal section it is where the plyback transformer is located resolder them and the CRT board this is the boad that is attatched to the picture tube...good luck

please rate my help..

Above are two service manuals, download BOTH and use them to sort out your problem if you can.
The Power supply, always start at that... Anyway please use this Service manual above, inside are all the troubleshooting and repair guides, circuit diagrams instructions the lot. &, well I applaud you for wanting to have a go and try to repair you set. But PLEASE, start in the right place, otherwise you will simply waste your time and money, You see, you MUST start, in the right place, The power supply, FIRST, as, if, that isn't right, nothing else can be. But you simply cannot do anything without a Service Manual. In this it has everything one needs to repair the set. OK if it is shutting down, after that amount of time, of working and then faulting, then it is most definitely a "Thermal" problem, the way we "Find" problems such as this is "Freeze Spray" you use this on each component that is suspected of being the "Culprit" and you will soon,find that errant component. Now, also not every fault is a Capacitor, I see many, many people that think, that Capacitors are always the "Culprit" and replace them, because someone else had done so and it worked, well that maybe sometimes true, but most Symptoms, can, and do have many, many different "Causes" & also, now while that may be true in a few cases, a faulty Electrolytic Cap, or even, ordinary, Cap goes faulty, this is only a SYMPTOM, something has damaged those caps causing them to "Fail". One MUST always find the root "Cause", otherwise if you just treat, the SYMPTOM, the "Cause" will just make the "Symptom" come back, in short order, as the prime cause still, hasn't been fixed., Now Capacitors hate AC ripple, or Over Voltage. Thats it. Oh.. and Heat, if these Capacitors, are too close to a Heat Source, then thats a prime cause of failure. Resistors, hardly ever go faulty,and if they do, it is generally obvious. However it doesn't hurt to check values with our Multimeter. Remember though resistors are made, with up to 20% tolerance from stated value, as such, are not too critical, unless in Timing circuits etc. Always check, the Values, of resistors, as with any other component, with the power OFF. Now Diodes especially "Zener Diode", are another thing to check, those and ordinary "Signal Diode" should always be suspect. next we have Transistors and IC's. The Transistors MUST ALL be checked to see if they have a good, "Junction" this is done, with our meter set to "Diode Test" and usually are about 0.6 to 0.7. With IC's you must check, voltage levels, or Logic Levels, going in and out, have a look at the circuit diagram, and it will tell you what they should be. It is a good idea to always measure the Power Supply voltages, see if a "Rail" is Low, that will be because some component has gone somewhat or all short circuit, to Earth, now, if the "Rail" is Higher, suspect an "Open Circuit" component, like a Diode, or Transistor. The voltages expressed in the manual are spot on, ANY variation MUST be investigated. I have been doing all this for over 30 years now, and I do indeed wish, we could have a set of "Symptoms" and be ables to say.. "Oh that;s the so-in-so and replace this" however unfortunately this although does happen, most "Symptoms" can have literally tens, of "Causes" all often "Interlinked" One simply has to do a methodical troubleshooting procedure, and always think, "are my Voltages Correct" as this is how, you Fix the problem, by making them so. Keep up the good work. If that link above doesn't furnish a Service manual, it is imperative you get one, even if you must pay for it. It will pay for itself in about 2 mins.
it is nearly always my professional opinion that one should always get a "Quote" from the manufacturers recommended service center, SONY, in your case, contact a local or head office, and ask for a referral to an Authorised service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

You may have to resolder your vertical IC. This seems to be a common occurence for many Sony TVs. This is my first diagnosis when I get one of these in. But, yes there could be a bad ground almost anywhere. You will need to pull the board out and resolder any IC mounted on heatsinks and any large power resistor and resolder the pins connecting the flyback transformer to the board. This tip is always the first place to look for in repair. Good Luck and be mighty careful. Thanks for asking!

You have bad grounds on the board..resolder these and check all you high voltage capacitors [200volts at less than 10Mfs]. These are common problems for sony Tvs. This is the general solution and I don't beleive you have a major problem yet. But take action now to prevent a major one. And yes replace the weak and bad caps!!!!!

If your TV was made after 2007 it should have the digital receiver built in. If so you can just hook any antenna you wish up and receive all your local channels.
