LCD TV White Blinking Light Standby Not Turning On | Power Supply Board Fault | Bad Capacitors Fix
This Toshiba LCD 32 Inch 32BV700B has a blinking white led light upon turning the tv on, but no image is displayed. The led light keeps flashing. On other makes and models, it can be also the standby light which remains on.
This problem is quite common with a fault on the Power Supply Board: ref 17PW26-4. A replacement board can be easily found on sites like Ebay for around £15.00 or under, usually a refurbished one. On this particular power supply board, the capacitors were blown, they looked clearly bulged out.
So I replaced the following capacitors:
2 x 1000uf 16V
1 x 470uf 35V
1 x 2700uf 16V
This simple straightforward repair did the trick, and only cost around £4.00 for the capacitors with an already owned soldering kit.
You can also order the whole replacement kit and replace all the capacitors which is something some technicians prefer doing.

I deal a lot with restoring UK slot machines, and deal with both the traditional coil style as well as switch mode (As used on this TV) power supplies, and certainly on the switch mode variant's, it's almost always a bad capacitor issue, which generally involves changing out ALL the capacitor's (We generally don't waste time or risk just changing the odd one or two, especially given the age), which vast majority of the time, will sort a switch mode power supply out well enough. Happens my Tevion md 30180 40 inch has just failed with a very similar issue as to what you describe here (PSU is a 17pw16-2 power board, and seams very common), so obviously one of my options is a re-cap, however as you pointed out, if a refurb switch mode is cheap enough, may save a lot of time and bother, just getting a replacement unit.

Most issues I’ve dealt with this kind of things was only the Fuse needed new one soldered on after the recent one bursts or short out on the power supply connected to the power cord that little motherboard will always be good it’s the fuse that never lasts on most TVs

Have just fixed mine after months, first it went on when it felt like then nothing. After watching a few videos on youtube I opened it up and it checked the capacitors, the 2700f16 had a bulge in the top, I found one in a broken tv, unplugged the 4 plug ins in the power board, undid the 4 screws, heated the solder off and took it out, put the used one in, two blobs of solder and it works perfect. Thanks very much for your vid

2:07, capacitor '2' is almost falling off the board, definitely suspect. :) Great video! Edit: Aah, I see you already unsoldered it.

Nice video, I know it's an old video but hopefully you can answer my question, I have a RCA 43" 1080p and it turns on but after one o two minutes it reset by itself and after another 1 or 2 minutes it restarted again, and the red light blinks while it reset, what woulb it be? Thanks

@HealMyTech1 5 жыл бұрын

Does sound like a power supply board issue, maybe capacitors, of the logic board, or it could be the manual control sensor? Hard to tell without eliminating issues, the tv needs to be opened and various voltages checked.

Check your fuse on the power supply if you can’t find an easy way to solder it in use a piece of Tin foil wrap it around it end to end or put it inside the little plastic holder.

Does anyone know if the tv plug has fuse in it that can be changed?

This needs for troubleshooting, back of TV needs to be accessed with a multimeter, only if you are confident, otherwise consult a professional

how to know the capacitor is blewn out ??

@paulrouk714 2 жыл бұрын

If you look at the top of the capacitor, the good ones will look flat, while the bad ones will be bulging up and slightly rounded on top.

Can anyone give me a tv diagnosis? When I go to turn it on sometimes I get no response. Then after a few tries I'll get a popping sound after I hit power, then it's off again. Finally after doing that a few times it'll come on. What's wrong with my tv? Please help!

@tcwyder2438 4 жыл бұрын

Check your power supply capacitors.Most likely you have one or more which are defective and need replacement.
