No standby but there is 3.3vlt on psu can someone help me to trace it?

Check all other voltages to the main power supply regulator board. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box.

Sony klv-32u100m no power

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.4_1_2012_2_50_15_pm.jpg

Do you still get any indicator light, i.e. standby. There are only 3 boards inside unit, main, power supply, and backlight inverter board. Need to check out the power supply board first.

Sony 32 lcd

This LCD could have a defective back light inverter board.
If your TV is less then a year old, still under manufacturers warranty. If not, I would suggest to contact sony and ask them for parts availability.
Let me know if you need further assistance.

My tv is dead no power in

Let's all us KVL32U100M owners sue SONY. For selling lemons and not wanting to support it. Their support web site will provide you with a refurb model as long as you are in the warranty period. Called service and it will cost me $600 out of pocket to repair. SONY thank you for the $1300 paper weight in my basement.
