Products a pains with steel bracket for heat sinks for transistors
mount.The heat sink design products must take a parts to replace
caps.Should alway replace caps with higher voltages 10v to 25v up higher so
this will never happen again with dead caps swelling up later the product
life.

My 4 yr old DYNEX LCD #DX-46L150A11 screen go blank 2 minute after u cut it
on, the audio works perfect.
This start to happen after wife clean screen with some solution called "di
Screen Dr"
I usually clean screen with a solution called "rocketfish"
I unhooked everything from the TV leaving it off for 24 hours, when i
hooked everything back up and turned on the tv it worked well for several
hours, when i cut off the tv believing it was fixed then cutting it on a
couple hours later the picture showed for about 2 minutes then screen went
blank again. what do i do?

PPS
In fact, only one of the two wires is damaged. It is not as I first
thought, melted, but has due to probable prolonged overheating insulation
that crumbling, particularly at points of contact with its neighbouring
wire and the metal screen housing which has rust at those points of
contact. The other wire remains soft and pliable with only a light
blackening at points of contact with the damaged one. Perplexed. Thx.

Автор Cecil Shalapata ( назад)
PS
I just found a wire with melted insulation at a point where it's attached
to together with the one next to it. These two wires come from the power
board directly to a board at the left side where I believe are the screen
bands. I guess this makes it a plasma TV. There is a twin transformer at
the point where these wires plug into the power board.
I guess the logic board is not involved and will put it back.
I'm not sure how to locate the actual problem. If you're able to guide me,
it'd be much appreciated. Thx.

Hello, I have 46 inch Samsung un46d6500vfxza tv, it started to give
horizontal lines, I tried to repair it by opening panel, when I tested I
was still having horizontal lines. I removed video cable and put it back.
Now, I do not have any picture but I get Audio. When connected to HDMI, I
see blue light and sound but no video. Do you know what could be the issue?
I visually checked Cd31 capacitor and QD2 transmitter but I don't see
anything wrong. Would appreciate any advice.

Is it almost like a chain reaction from a power surge or just the time

when I replaced it and plug in the tv it just gives me a dim green light
now. I have tested the dc volts going to the mainboard and they all seem
fine even my 24vsp seems fine. should I replace every capacitor on this

Hey Tampatec. First i wanna say that i love your videos, i even Watch your

I have a problem with a tv that i hope you know about.
My tv has only sound in short periods, somewhere between 10 and 30 sec, and
then the sound suddenly go crazy with a noisy sound and then shuts off.
could the problem be a broken capacitor ?
non of the capacitors are blown by the way.

will help to determine if the problem is your backlight inverter or the
main board. Here is a link to the video: No Image No Picture on

min. Did this 4-5 times. I opened it and didn't see any bad caps to the

double check plug and solder connections and check more caps and make sure
caps and in the right way. if no go then just buy tv powerboard its around

residue..........my tv has sound only and the blue power light comes and
stays on. cant seem to find a cap kit for my model.

Автор tonyz2897 ( назад)
Is that a proview ipos 150 board? I just trash picked a poleroid tv with
that board and the ec17 cap is visibly bad. I've got new caps for ec17 and
18 (10uf 450v) on the way, but I'm wondering if the caps going bad normally
damage anything else? The reason being is there are no component suppliers
locally and I'd like to order anything else I might need so I'm not waiting
another week for components to ship if the new capacitors alone don't fix
it. Thanks!

Thanks for the suggestion, but I'm afraid that didn't do it either. It
start'n to look like a problem with the signal processor board... figures
I'd get a more expensive problem instead of something simple like a PWR
