SOURCE: Red Dots

You can get rid of the red dots by adjusting the V-scan voltage down, it's on the panel sticker inside the unit, you can find the test point on the DC to DC pcb, and the adjustment pot is on the same board, lower it as you watch the screen and only lower it enough to rid the screen of the dots

SOURCE: Samsung 50" plasma won't turn on

My 42" plasma is making a clicking sound, then it switches off and keeps clicking but not switching back on, when it does go back on it stays on for just a few moments, it is only 14months old.

SOURCE: 50" Samsung Plasma with black screen

I had the same problem and had the TV serviced and found that the y board was blown $350 total. The repair guy explained that the board has a hot transister underneath that slowly leaked onto the board, but says that they can not get Samsung to admit to the problem. Works fine now but only have a 90 day warrenty on the parts.

SOURCE: Have sound but no picture on Samsung plasma

It's a pretty common problem. The no picture but sound problem is usually the y sustain board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!

I have a samsung 50 plasma tv that will not turn on now. If I unplug it and plug it back in it makes a clicking sound 4 or 5 times then nothing happens.


Probably bad capacitors. Samsung TVs are famous for this. Relative easy fix for a technician that knows how to do board level repairing

Samsung plasma tv made a really loud pop and the screen and sound do not work but the red power light won't come off unless the tv is unplugged what happened?


The main power supply regulator board has the fault. Check if any electrolytic capcitor/s has bursted out. Replace them if any. If this do not help you. repalce the board as card basis.
Replacing it as card basis is fine, rather than making 'surgery' to it.

Philips tv model number 50PFP5332D 37 wont power up


I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.com
