I think your problem is in tuner stage.

1. Check 32V dc available on BT connection on tuner.
2.If 32V available on BT,connect dc meter and put the unit on auto search and check the BT pin on tuner.The BT voltage will decrease and increase while it tunes.
3.If nothing stored after programming replace tuner.


Good luck

    Hello,

    Here is the part number for the tuner 8-598-430-50 or 8-598-430-30

    when you install tuner very careful,because this is not the original tuner.

    You need to remove pins 16,17,18, and 19 from tuner then install.



    Good Luck

Hello,
turn of the TV, remove it from wall and try it in another outlet. Also, connect the TV to a DVD player. If there is still no sound and picture after connecting the TV to a DVD player, then it means the TV has developed a power problem.
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 a Sony Trinitron KV-32HS500 that won't turn on. It blinks 7 times. I was told it was a power supply problem. What part do I need to fix this?


The Power Supply/ Deflection Board is called the "D" Board. Replacing this Board should fix your problem. You can try to order one from Sony at 1800-222-SONY. If it is not available, you will need to send it to Sony for them to rebuild it. That will cost around $400.00 or so.
I hope this helps,

Sony 36" Trinitron Problem


Good day.
There may have been some problem in the horiontal transistor. Also, Check for the zener diode that controls the supply going to the flyback. It might got busted due to the sudden supply surge.

Sony Trinitron Power Surge 5 Blinks


once you have diagnosed the problem, the following link is to all parts for your tv stocked at partstore. they generally have better prices than the dealers and repair shops.
KV-36fs13 parts

you can try the dead-tv kit from fixyourowntv if you have some basic experience with soldering and circuit repair.
http://fixyourowntv.com/orderpage.php

Five blinks means, "IK (AKB)" (white balance). The probable causes listed by Sony are as follows:
1) Video OUT (IC561) is faulty (A board)
2) IC355 is faulty (A board)
3) Screen (G2) is improperly adjusted.

not sure what the 13 blinks are for.

hope this helps,
