Do you know how to check resistors ? If so check the big block type that I have zoomed in on in the picture:Attached FilesPlease Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

Re: hitachi 42pd9r10 dead
Well--Whatever you do--Dont waste dosh on it!
Every one of these Ive seen--Inc the Philips that used the same panel/chassis had a clapped out/cruddy PDP giving awful mal-discharge and nasty green fringing on fleshtones...
Fujitsu/Hitachi used a low voltage PDP (65V Vs,--everyone else uses around 180-220v) with poor aging characteristics...
Orrible bloody things, I don't bother with them anymore...TELEFIX
How PLASMA SCREENS WORK, X-SUS and Y-SUS what they do--

Re: hitachi 42pd9r10 dead
Have you checked the white ceramic fuse on the board along side the connector or even the fuse in the 13Amp plug?
Edit
Just reread your first post in which you say you have checked both fuses.
Have you checked the On/Off switch to see if it has gone open circuitLast edited by dick_barton; 03-14-2016, 05:47 PM.Willing to help but I'm no expert.Comment

Hi everyone,
I have a dps-162kp-1 runtka932wjqz powerboard wich has no power at all on the cold side.
I replaced ic7903, r7900, R7902, C7901, d7950.
Checked the diodes around the chip and also the caps.
On the ic pin 5 no voltage, pin7-8= 315V
On the T7901 pin 1-4 no voltage, pin 2-3=315V
Anybody have any idea where to look further?
Any help is welcome
Thanks Danny from holland -
Hi all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
I couldn't find any other thread that matches my TV problem but have been told it is a common fault. The fault is a flashing LED as if it is in upgrade mode that happens after a few seconds and stays forever. I can't remember all the tricks that have been tried like holding the select button when powering on but nothing worked. The shop sent me a flash drive to plug in a USB port but that did nothing either and they said it was dead which is disgusting for a piece of solid state electronics. I took the back off eventually after removing 34 screws to check for blown caps but everything looks new... -
hello guys,
i need help to repair a edm-033 ps2
history : as always hdmi port and usb ports destroyed after unplugged
after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
so i changed it
now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...
i don't see any projection of liquid metal on pcb.

Hi guys!
I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
I have a bench PSU and if I try to inject voltage the voltage...
