i replaced 7 bad caps on the power board of this tv hoping that would fix it. The tv powered on but no picture after looking on this forum found a thread about testing the ysus board. they said the was a resistor to test the vy voltage that should be 200v. testing this resistor there is no voltage present. any help would be great.

Re: lg plasma 42pc1rr ysus problem
Check the Vs fuses on Y-sus -- most likely one is blown and you will need to replace IPM or Y-sus.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: lg plasma 42pc1rr ysus problem
thanks for the reply have checked the fuses they are ok what is the IPM and were do i find itComment

Re: lg plasma 42pc1rr ysus problem
Do you have 200V at both ends of the fuse relative to the chassis?
Post pictures and we can point out IPM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

China LED TV Board,TP.MS608.P83
My dear we have a problem in Karachi to repair china fake Sony led TV MODEL: TP.MS608.P83 (Asia).These models are running in the market in various model and selling in hug quantity.
Customer said that TV was on but window appear on the screen that (launcher 4.0 is not responding, close the application or wait) customer press the close,
Now TV is on standby mode and not responding anything and we have no flashing or reset idea for this model so please give us an idea to solve this problem.

I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down

I have an LG plasma that after reading through a bunch of posts and doing some testing I believe has a bad YSUS board. The problem is that that doesn't make sense to me for some of the symptoms. The problem started yesterday. While watching a movie the TV just shut down like I pressed power. I have it hooked to a PC and use RS232 to turn it off and on so I thought maybe something had glitched there. I turned it back on and finished the movie with no problems. The same thing happened today so I checked logs to see if something in the control glitched and sent an off command but it didn't, After... -
Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection... -
Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...
