SOURCE: Pioneer PDP 5030 power supply problem

Ok here's how I manage solve the problem... Having the back removed opens the contacts on the interlock switch so I guess if it powers up in this state it senses the high voltages are exposed and for safety shuts down... After this the unit will not power up and the power led flashes red continuously as described before…
After some thought it occurred to me that there may not be a problem at all, just be a simple reset function for this condition… I managed to find an easy solution to this… Just call up the hidden engineer’s service menu – On 3rd generation Pioneer Plasmas it’s as follows > Power down the screen > Hold down the “Input” and “Vol +” buttons on the front > Power the screen up and the Service menu comes up on the screen > You don't need to change anything just simply power off and from then the screen should operate as normal…It did for me so I’m well happy now!!
I hope this information will help someone else one day – Good Luck!!…Rob UK…

SOURCE: power shuts off and blinks red .

I had a similar problem, but mine didn´t switch on when pressing on button, I had to take the back cover off and hit the relays, it seems they get stuck, and are difficult to find to replace them. Now it has been working during almost a year with no problem at all. Mine is 4 years old.

SOURCE: My samsung plasma suddenly made clicking noises and tuned off

I wish to tell the world about the simple cheap fix for your plasma! . Please let me know if I helped. I have a 50" Plasma that deicded after a year it didn't want to turn on anymore. It just blinked red LED. Which made me see red! It took me a year to find this inexpesive fix I hope this information will be helpful to you.... These are spendy items and none of us were thinking that after a year (seems like a scam to me) the TV just won't turn on anymore.... Then they say your no longer covered under warranty or you are and they send you to some repair shop 1-2 hours away and always and I mean always tells you the part is on back order.

Lukster is right it is a power supply problem. However you don't need a new board nor do you need to pay someone a ridiculouse abount of money to fix this. I fixed mine for 40 cents.

You more than likey have bad capacitors.
Unplug the TV from power. Remove the back cover. (some models require a star srewdriver) You power supply board is right in the center. A bad cap is bulgded or raised. A good one is flat. caps have an X on the top of them. More than likely you will see a bulding or just straight raised edges on the X on the top of the caps. Cap 3300uf 10v is the ones you are looking for. Once you find them replace them with 3300uf 16v caps. If one cap is not raised replace it anyway. These caps need to be a higher voltage that why the tend to pop. 16V is plenty, don't go any higher in voltage than that.

The caps need to be soldered on. You have 2 options do it yourself or unplug all the wire harness from the board then unscrew the board take your power board (dont forget your new caps) down to a pc repair or tv repair and have them solder them on for you. It will take less than 10 minutes. I do recommend putting the board in an anti static bag. You can buy these caps at radio shack or buy them on ebay.

After you get it repaired replace your board plug all power supply wire harness back onto the board (I recommend numbering the wires as you remove them), replace the back panel cover. Plug her in and fire her up. and BAM it works. then turn it on and off a few times in complete amazement at how simple and inexspensive this was to do. Then get angry cause your repeated calls to tech support was wasted breath.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis.
http://electronicshelponline.blogspot.com/
Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

My hitachi plasma tv model 42PD5000 wont turn on.the red light by the switch wont turn on either.i have checked fuse on plug which is ok.please advise what may be the problem. Thanks Roberto


Hey,

A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.if otherwise, the power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this will help to fix the problem and do take care in handling the problem.....

HP-R5052 reboot


It's definitely an overheating problem if your plasma turns off by itself after a while. I would suggest to place a cooling fan near the back of it as a temporary fix.
There could be a power supply issue along with a Ysustainer board but in order to know that for sure, you should use a hair drier and blow hot air to the power supply and see if the TV turns off, if the time that the tv turns off is shorter when blowing hot air to the power supply; then is the power supply issue.
Good Luck.

Phillips Plasma 42" TV


It is most likely a power supply failure and if there had been no signs of problems in the video display, it is probably the main power supply rather than one dedicated to the plasma display itself.
You might leave it unplugged overnight to give any stored charge inside the unit a chance to bleed off, the remove the back panel.
The primary supply is normally on a separate board and is characterized by having mostly larger components, including one or more transformers with black ferrite cores. The main supply will be associated closer to the AC input while the high voltage supply which may or may not be separate is not.
If you can locate the board with some confidence, check it visually for any signs of heat such as discoloration of board or components. If it seems OK it may be a candidate for exchange or repair by Philips.
I wouldn't advise removing and sending it before you talk to Philips to see if this is a familiar problem to them.

You need to fix power supply module (replace electrolitic capacitor on PCB) in your plasma. It's very frequently failure for this device.
