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.

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

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

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.

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..

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!!!!!

Hi
I need to know exact model number of your Sony TV to diagnose problem.
Question shows its KV-35S42 that is CRT tv.
Thanks.

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.
