Re: Samsung S19A100N ghosting picture..
The panel is the fault, the only fix is to replace the whole lcd, and finding a replacement is difficult, so i've given up on this monitor and bought a new one.

Re: Panasonic TH-L32C20CX
Finally fixed, I found a corrosion on the A board at the back of the lvds cable, luckily that didn't cause too much problem, I cleaned it, and to my surprise it came on, didn't know where that corroded path was going, so I will know what the sos 4 blink, but never mind, I had too much time on this one, thank's to all that helped here!...Leave a comment:

Re: Panasonic TH-L32C20CX
Looking at the schematic of TC-L32C22 voltage reference of power board, my voltage readings maybe low, like the 12v reference i only get 10v, and 17v i get 15v, any idea where should i check? Thanks.Leave a comment:

Re: Panasonic TH-L32C20CX
Here are the power measurements from power supply, pin 1-16, it is taken when the tv is powered on (blinking green light) before the set shuts off with 4 consecutive red light. Are these voltages correct?
Pin 1&2 - 5V
3. - ground
4&5 - 10V
6. - ground
7. - 15V
8. - ground
9. - 2.2V
10. - no contact
11. - 5V
12. - 2.2 V
13. - 0V
14. - 0V
15&16 - ground...Leave a comment:

Re: Panasonic TH-L32C20CX
Hi tom66,
i've searched your tv repair reference library but did not find my model, instead i found this model (TC-L32C22) that has same pics. Of the power board and A board, what do you think? Power blinking 4 times says the problem is DTV12V_SOS, would this mean i need to check the 12v power board rail? If the 12v from power board is ok, where should i check from A board?
Thanks in advance...Leave a comment:

Re: Panasonic TH-L32C20CX
I've resoldered some cold joints and tried replacing caps even if not bulged, still nothing, there's no voltage label on the psu board so i'm blind with power measurements, any ideas What to do?Leave a comment:

Panasonic TH-L32C20CX
The problem with this tv is if left unpluged for several days, the tv will powerup normally for few minutes then suddenly it shuts itself off, trying it again to power the tv on it gives 4 blinking red light, what do you think is the problem?... -
Re: Multi colours on Samsung LE40M86BDX.
My experience after replacing an as15 chip, the broken chip heats a lot (using my finger) but with the new chip its cold, before i was planning to put a heat sink but realized its not the overheating that cause the failure, maybe bad manufacturing or design?Leave a comment:

Re: Sony klv-37u300a t-con issue
I agree with tibimakai, and tom66, voltages should be decreasing, the chip is compatible mine is as15-hf and replaced as15-f worked fine, i suggest you double check your solder, i had problems replacing the chip, thought its well soldered but not.

Re: Samsung S19A100N ghosting picture..
Hi,
Thanks for replying, the ghost image in the attached pics is when theres no connected cpu, i can see the no connected input box moving around the screen but blurry, is it a bad panel?
