As above click the power button then keep hold of the standby button on the remote green light flashes for a bit then goes green if left on standby it clicks after about 5 mins once in a while it will come on and stay on then when you turn it off it will do the same any ideas

Re: Panasonic tx-l37s20b will only turn on some times
Well, what have you tested.......? Anything at all? Tried heating and cooling? Monitoring PS voltages for stability and accuracy?
If you get stuck on a particular issue, here's the place to ask, but quite frankly you've done enough TVs that you should realise there are obvious steps you should do.
For example, check P/S voltages when working and faulty. Try heating stuff up using a household hair dryer see if it trips out earlier. Enter service menu and check fault codes, if any. Stuff like that.Last edited by tom66; 12-02-2014, 05:46 PM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic tx-l37s20b will only turn on some times
Hi yes tried the voltages from the power board all seem present and correct from the power board seems like some of the av board is getting power but non at all to the t con but it would not be if if it was not switching on properlyComment

Re: Panasonic tx-l37s20b will only turn on some times
If there was no supply to the T-con board you would expect no image. It MIGHT trip a fault code. I would look elsewhere right now.
Use the service manual to locate power on/off signal, check if it is operating correctly (should change from LOW to HIGH or HIGH to LOW when TV tries to turn on)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Where would I find the manual for this tv?Comment

Re: Panasonic tx-l37s20b will only turn on some times
Check my signature, also elektrotanya, eserviceinfo, servicemanuals.pro... Also Google.
Maybe tw2005 has a good source. He's good like that.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic tx-l37s20b will only turn on some times
How can I test that 5ws10 only reason im asking is there was a lg I had with the same type of issue would not turm on and I got a kit from ebay and worked perfectlyAttached FilesComment

Re: Panasonic tx-l37s20b will only turn on some times
Just a resistor. Should measure approx 10 ohms (hence 10 followed by horseshoe symbol - omega - meaning ohms)
Test out of circuit for best measurementPlease do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic tx-l37s20b will only turn on some times
I measured it in circuit and the reading was up and down up and down goin to remove it and test nowComment

It's rare for those resistors to fail intermittently. I'd try hot and cold air to see if it's thermal.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Have to turn C1 on and off multiple times for it to fully come on
Have to run LG C1 on multiple times for it to fully work
If I have it off for a while I have to turn the TV on and off and handful of times for it actually display what it's suppose. The times it doesn't nothing comes up like the input or dobly vision logo. Once it's on I can turn it off and back on fine and the picture looks perfect.
Unhooked everything except antenna. Reset tv to factory settings. Let it sit and when I tried 2hrs later turned TV on and sound comes through but no picture.... -
I get no image nor backlight, standby light blinks 13 times then stops. Any clues what it could be no evidence of damaged componentsYesterday, 04:08 PM -
Hi everyone, I have a Samsung NP750QFG-KA3DE , MainBoard VESTA3-15 BA92-24515A
the battery is charged. pressing the power button the blue LED flashes 3 times and then stays blue. then the sequence repeats.
the fan does not start.
I noticed that I have no power on the processor and it does not heat up. could it depend on the bios?
any advice on what to check? -
Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited... -
I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
Unfortunately the whole machine has to come apart to fix it.
I have...
