Timer light


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.4_19_2012_2_36_48_pm.jpg

Don't know where the fuses are on the Sony kp-53s25 1996 year. Tv won't turn on, makes clicking noise and then standby light flashes. harrism55@yahoo.com


the first thing you can deduce is the main fuse is good. secound the power on relay clicks whick means the set is trying to come on. the standby light flashes... how many times what is its pattern this could be an error code that could point in the direction of the problem

Sony kp-46wt520 rear projection tv: standby light flashes


Two things here.

1) This is a CRT based set so there is no "lamp" involved.
2) The standby light should be blinking a repeated count of blinks with a 2 second pause between counts. Please report the exact count here. This will indicate the circiut in which a problem was detected.

With the above information, we can provide you with a more detailed description of the problem as well as the likely solutions and cost.

Thanks,
Dan

Blinking standby light and nothing else...


When Sony TVs detect a problem, they shutdown and present a blink code. The blinking should be a repeated count. Please report that count here as that indicates the circuit in which the problem was detected.

Sony KP-51WS510 Shuts itself off


eight blinks means, "High-voltage error" and the probable cause location listed is, "T8005 is faulty (D board)". T8005 is the fly-back transformer assembly.
