Re: Onei 26av400
Mkay, looking at schematic:
http://www.tgohome.com/ServiceManual...&Search=Submit
that diode should NOT appear open...
That would cause loss of 24V audio supply. I can't be certain if that would just cause lost audio or other problems.
Check across C931, C961 and C962 for 24V.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Onei 26av400
Thanks tom,how do i check them c931.c961.c962Comment

Re: Onei 26av400
Check the voltage across them, expect 24V.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Onei 26av400
The same way i checked the diodes with the multimeterComment

Re: Onei 26av400
No, use the DC voltage scale this time like you check a battery.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Onei 26av400
with the setting to v-
so if the cap is 1000uf switch to 1000 ?Comment

Re: Onei 26av400
ignore the c931 quoteComment

Re: Onei 26av400
c931.c961.c962 all been changed and still the same problemComment

Re: Onei 26av400
You did not need to replace them. I asked for the voltage across them.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Onei 26av400
i did test the three and was not getting any readings,so i changed themComment

Re: Onei 26av400
That was not necessary. Lots of things can cause that. When plugged in though, TV should do a self test. So hold meter across leads, plug TV in, see reading.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Onei 26av400
so what have i got to test now ? can you explain why the power/standby light will flash even when the power is pulled.Comment

Re: Onei 26av400
Hold meter across leads of one of those caps, plug TV in, see if reading spikes.
TV has capacitor that stores charge, like battery, when unplugged. So it will run for some time with no power.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Onei 26av400
just the one ? or test all three,could i ask what to select the multimeter to.Comment

Re: Onei 26av400
ok so basically place both leads on cap and see if it holds a reading or drops etcComment

Hello,
I've been given an Alba CBB16 radio to look at. The issue was no sound from either speakers when switching to the radio. They'd just be some buzzing/static. I did some troubleshooting and found that if I mess with the switch in certain ways, the sound cuts in and out on the right channel speaker. It'll go from quiet with some static/buzzing to really loud and clear depending on how the switch is moved. This told me that the radio at least has an issue with this switch.
The switch appears to be broken on the inside causing a poor connection. I tried cleaning it...07-29-2024, 07:05 PM -
Hi all.
Im trying to access the sd card in my ALBA 10tablet directly from my pc, but when I connect using using usb its only showing the internal storage.
I have a samsung tablet and it shows both internal and external storage when connected but no dice with the Alba.Is there some setting i'm overlooking.?
My grandson has an amazon tablet and again the sdcard is not there when plugged in to pc.
Thanks for any help.08-18-2022, 12:08 PM -

Hi this early vestel with inverter and ccfl backlight came in with no backlight and it was the usual suspects on the inverter board ,4 fets ao4616 ,i ordered a kit and repaired inverter .
i now have this smear approx 8 inch from bottom on left hand side
its about half inch wide it stops approx 3/4 across .it doesnt change with pic content
i have examined panel closely for any damage ,
none of the tabs are running hot .
would value your opinions if it is the panel.
ive had many plasma and lcd tvs with horizontal lines,
but they usually go right... -
