Tv won't turn on

So I removed the back panel and found the faulty capacitor....what do I do next? The capacitor read " B 152K 1KV. How do I find this part? How do I replace the burnt one? Will this fix my problem or is there something else I should be doing?

I have a RCA 32" Flat Screen TV that shut off and


Hi,


The sound was came from the clicking of the relay. This kind of symptoms is an indication of out-of-regulation condition on the power supply section. This is caused by faulty electrolytic capacitor. It will dropped the supply voltage and will trigger that kind of symptoms.


Faulty electrolytic capacitor mostly has a physical indication of fault like bulged/dome at the top and can be easily identified. See sample picture of faulty electrolytic capacitor below.

capacitor with bulged/dome at the top.


Check these parts on the power supply section. Once found, replaced it with same capacitance and working voltage which is printed on its body itself. Click this LINK for more info regarding electrolytic capacitor.


If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qualified TV Technician to isolate the faulty parts.


Hope I helped you.

Have a nice day!

Thanks for using Fixya.

The tv shuts shuts off by itself and wont come back on until next day, do you know what causes this


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Blown Capacitor and diode


I had the same problem. My nephew gave me this set after it quit working at the Gym where his wife was working. They were going to junk it but I asked if I could try and fix it.
The capacitor C2250 was definately blown and easy to spot so I did some searching and found a replacement from an online electronics supplier that didn't require me to buy 200+ as Digitech wanted. Anyway I replaced the Cap and it still didn't work so I started looking and testing components again and found that the Diode D2250 was bad so replaced it as well and now the set works fine. Maybe this is what is wrong with your's and others as well.
It made sense for me to check the diode as it is right next to the cap that blew. https://www.mouser.com for the Cap and http://www.slelectronics.net/ for the Diode.
The specs for the Cap/ CERAMIC CAP. B K 1500pF/1KV
The specs for the Diode/ SCHOTTKY BARRIER DIODE YG123S15

Sylvania 6842pf m after i power on inmedialty power off (stamby)


These sets are manufactured by Funai, in my opinion total junk, yet they command a $1,500 price tag. I cannot find parts available for this hunk of **** anywhere so if this tip helps you fix this set and get it out of your hair, God Bless You! Model number is followed by an M to read: 6842PF M Found no VSUS on connector CN2502 of the SMPS. VSUS was shorted to adjacent GND pin by 120 Ohms. Small high voltage blue capacitor C2250 (Between Two very big electrolytics and right next VSUS diode D2250 (TO-220 package) on aluminum heatsink) shorted, burned. I have two of these sets in the shop at the same time, both of them have the very same problem, appears to be common and parts seem to be NLA for this unit. Replace C2250, 1,500 pF @ 1Kv. Usually marked as 152K on small high voltage capacitors in junk units. This is not a common value part so if you have to, make one by parallelling a .001 uF cap (102) with a 470 pF cap (471) to get a suitable 1,470 pF capacitor at 1 Kv. Adjust VSUS with VR2250 on SMPS board to read 175 VDC to GND and you are done. You're welcome. ~Ohmster
