Blown Capacitor and diode

I had a capacitor & a diode go out on the main board. I have no Idea what the specks for the capacitor is. The writing on the capacitor is gone, that side blew out, and I can't find any diodes that match. The diode is in the D2250 slot on the board and the capacitor is in the c2250 slot. There are other capacitors on the board that look very similiar and they are a 221k 2kv capacitor but I'm not positive that they are the same. Any help would be greatly appreciated.

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


Hope this helps

I know this is very late, but my 2005 Sylvania "6842PF M" just made a loud pop /with smell of burnt electronics when I hit the power switch the other day. The capacitor in slot c2250 is a 152K / 1KV which translates to a 1.5nf Ceramic dic @ 10% tolerance at 1 kilovolt max . The diode in slot d2250 is YG123S15 Fast Recovery Diode. My cap blew out the side leaving the #'s intact. It blew out onto the diode, pitting and blackening the heatsink that it is attached to. My digital multi-meter shows the diode to still be working in its Diode mode, but I am not going to take a chance, and biased on other posts, going to replace both. I have found both parts on the WEB, and am looking for a single vendor solution.

Techwood flat tv wont turn on for 3 days


Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

HPS6373x/XAA Power issue


Needless to say, it's probably not a blown capacitor. If the unit will not power on at all (control/standby indicators are not lit) the problem may be as simple as a blown fuse on your SMPS (near the AC socket) or on your Main Logic PCB. You should also use your fluke/voltmeter to verify that the Vs, Va, Vsc, and Ve values are reasonably close to those specified on the panel label. Re-post your findings!

Hp2710m capacitor blown


Look for any short circuit around, short zener diode, short transistors or diodes. Look for any excess voltage in that area where you found blown capacitor. Then replace it and see.

Television power light is on, but can't do anything with the television. Have tried ALL of the potential fixes listed on the web with regards to holding the power button and have also called Sharp.


Sounds like a blown capacitor on the main power board. look for the cylinder shaped capacitor on the board that the top looks bubbled up (rounded not flat). It's usually 2200uf capacitor. you will have to unsolder it and replace it or just replace the board. Capacitor $5 board moe like $200. try the cap first. they are available at radio shack. may be different in size. you will have to run extra wires to the new cap sometimes.

I have a blown power supply board for my Samsung SP5207HR Model EX5207 Version 1 rear projection televison. I trying to locate the following parts to repair it: 1 schematic for Samsung SP5207HR ...


The components that you require will be freely available but a stockist will need to know what they are, The transistor will be, for example 2SD1308Q the diode maybe a 1N4007 and capacitor say 33nF. To find the values, look on the component and it will be printed on it along with the manufacturer's idents and date codes etc.
Hope that helps you get a result.

My plasma tv keeps on blowing the fuse? any idea why?


Check SMPS circuit.

Check whether any diode is shorted itn the supply line. Start from the AC line, diodes, capcitors. Check SMPS Transistor mounted on heat sink.

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

If you are certain that the capacitor is OK, there could be a different problem on the main power board or even on the sub-power board. The sub-power board should have output voltages even if the main power board is defective.

Sanyo DP42746 won't turn back on


I basically paid $1,000 a year to have this piece of grud. I am having the same problem everyone else is. It shuts off by it's self, then when I try to turn it back on, it shuts it self back off or the picture looks like its having a hard time showing. Very frustrated and feel ripped off.

Sylvania 6842PEM


Have fixed a bunch of those as a Sylvania ASC. There is a small ceramic capacitor on the main power PCB that has ruptured. It must be replaced with a different part, a special type of capacitor, or it will just fail again. Sylvania had recommended replacing the main power PCB rather than repair because sometimes there was additional damage on the board, however replacing the capacitor fixed every one that came to us. I preferred that because some electrical voltages have to be adjusted if the circuit board is replaced with a different one.
