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!

I have a lip sync problem with a JVC LT-19DD30J LCD TV


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board
power%281%29.jpg2_23_2012_11_31_16_am.png

After replacing blown capacitors...it should work again.

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps

TV was unplugged for a little while and now won't power up and is making a buzzing sound. What can cause this?


How old is the tv? This is a power supply symptom. You will need to take the back of the tv off and check for puffed capacitors on the power pcb. This is the board where the power cord plugs into. Lay tv face down on a cushioned surface large enough to support the tv frame. You do not want to damage the panel. Then remove the back. If there are puffed capacitors, replace them with equal or slightly higher valued capacitors. The value rating for capacitors are mf and voltage, printed on the capacitors. If they look good, you will need to check the dc voltage output from the pcb usually about three connectors in the same area. One way or another, it is a power supply problem, usually corrected by replacing caps, but if that doesn't work, you will need to replace power pcb

My Model LN32A330J1D LCD TV will not power on even though the red stand by light on the power switch is on. The unit is only one year old.


Hi, Try my methode,
Open the rear cover, there 2 PCB board. SMPS board and Main board.
Check on SMPS board first, check capacitors on it, check if any capacitor like almost exploded. If you see that part, replace it with new and higher value (1000uF/16V to 1000uF/25V).
Or, unplug T-con cable ( cable from pcb main to Panel board). plug in ac cord and try to switch on your TV, if its working , that means panel has problem.
I hope that will help you.
If any problem with it, please send me a comment .
Thanks.

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.
