Sony KV-35S42 35" TV Questions & Answers
Panasonic tc-p46g25 four blinks
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.

Hi,
6 times blink shows problem with back light inverter board.
TV requires back light inverter board replacement. If you have electronics repair experience and want to repair TV by yourself, let me know to guide you part purchase.

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.
I have sony triniton tv when i was turn on there
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.
I have a semi-transparent shadow
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.
My Trinitron KV-35S42 picture folds up.
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.
Sony tv kd32nx100u. watching last
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 .
Tv was dead no vvidei no sound after checking
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.
Can I recharge a Sony CRT ? or deep six?
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.....
