\015\012The only generic advice I can offer is that you do not trust a cold check of the caps because one might be breaking down under load.

I have not serviced one of these models before, 26XR9DA. The problem is no Picture Sound OK. The Bachlights come on for about 3 Seconds with Sanyo LOGO visible then go off with the High Voltage inverters powering down. 5 12 and 22 V lines are clean and steady I have changed a few electro caps but this TV seems too new for the common caps problems The B ON pin sits at 3.2 Vs and never changes during startup etc. Im hoping there is a common fault for this symptom. Any help is most welcome


Hi mroulston,\015\012\015\012First check the brightness of the logo when it's first come on, you will notice that there was a slight changed in brightness if the one of the backlights was already busted. This is the very common fault I've encou ... Flat Panel Televisions

I have a Samsung 55 in LCD tv that keeps powering on & off. I checked the caps & they look good and have the higher voltage rating of 25 volts not 12 volts. Any idea what the issue could be?


The capacitors can fail and show no outward signs. You need a special meter to check them. Without a schematic and voltage test points it would be hit and miss trying to find the bad part without the right test equipment. ... Samsung LN55B650 55 in. LCD HDTV

I have the Hisense TL2020 that won't come on. I read the solution to replace the caps. So I pulled out the (3) 1000mfd electroitics but they were all three 16V NOT 25volt as stated in the solution and I don't see a 220mfd at all. Should I replace these three with new 16 volt or new 25 volt electroitics??? Thanks for the assistance

I have a Sharp LC-19DV12U with a defective D501 labeled 10E241. It is located on the power supply pcb connected across the 120v input to the board. The board does appear to use conventional identifiers (c=capacitor, r=resistor, t=transformer) so I would expect it to be a diode although in fact it looks like a ceramic disc capacitor. Unfortunately, I don't have a tech manual or a parts list. Can anyone help with a part number?

It will stay 'on' for 3 seconds and then the relays will click on turn off. No red optical light. If I test the P25 connector pin 1 voltage it will go to 15 Volts for about a seconed and then 0.

Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens. I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver
