Tv won't turn on. replaced bad caps and after some testing it turned out that the power supply board wasn't giving the supposed voltages.


This problem is not easily to be solved.Tries to changes all the capacitors components even if u think is good around the bad capacitors surrounding area.After that,if u still have the same problems.This problem could be any high voltage components parts like transformers to ICS power regulator.Trying to fix this power supply board probably beyond your ability and u must also have the tv power supply board original schematic and electron scope too . .To measure those power transformers and ics power regulator output.Tries websites like Shopjimmy.com,EBay.com to buy a whole new refurbish tv power supply board for the replacement that is ur best bet.

Help new power supply will not power up.


if you had a surge, it could have damaged more than just the power supply. When you plug in the unit, does the power indicator light up??? your main board could also have damage. The main board sends a signal to wake up the power supply thus turning on the TV. If you have to replace the main board as well, it probably won' t be economical to repair the set.

I accidentally overheated my Panasonic Plasma TV TH-42PZ700U. It won't turn on, and the power button blinks TEN times.


Check and see if there are any blown caps on the power supply. If there are replace them or change your power supply.

Thank you

Hi, I still own a Sharp VCR Model no. VC-H670X. Has been too good to part with. Unfortunately, it won't power up. Having a technical background, I have found that there is power on the primary...


Hi, I would say to you get rid of it. In this time of HDTV's You will no longer be able to record a program with it. It will all be in Digital. But you can still play a video. To record a digital program you will need a PVR (personal video recorder)or DCT.
Check the plug for power. Use another plug.
If it cost more to fix it, you better think about it some more. Good luck.

Hi,

I'm going through here just to share the circuit diagram (schematic) for Boss PSA adapter because I know that many people need to repair their damaged fonts but can not get the original wiring diagram.

Hello naomi1972,

If you checked the fuse, and it is good but the set remains off, this is an indication that you primary power supply has a problem. At this point you will need to have the schematic diagram to check the voltages on the power supply board. If you have a background in electronics you can do this with no problem, however if you do not have a background in electronics, I would suggest that you have a qualified TV repair person fix this TV for you.

My diagnosis of this TV is that the power supply board may be defective. This is the best I can offer with the information given.

I hope this helps,

Thank you,

Plasma went black. Power not interrupted.


Vladislav fixed his TV already by replacing some defective capacitors in the power supply.
The locations of the defective capacitors are C523 and C524. The value is 0.22uF/400VDC or can use 0.22uF/600VDC Polyester coated.
Good Luck.
