Main power supply which has the standby supply with it--look for those pesky puffed up filter caps.

SOURCE: Sony Big Screen TV Not Powering On

This looks like a problem with the High Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.

In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,
Thank you,

I Have 2004 43' inch Daewoo model DSJ-4710CRA will power on but cuts right back off any fixes?

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

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.
