My RCA 40" LED TV will not power on.
My 40” RCA LED TV has no power or led lights lit. I tried unplugging, holding on the power button for 1 minute, waiting 10 minutes and then nothing. I do hear a clicking sound at regular 3 to 5 second intervals when I plugged it back in but nothing else. Here’s internal photos, what should I try next?
Hi Garisit, for first, exchange all electrolytic capacitors on the power board and logic board.
I appreciate your time and help but this repair is beyond my abilities and professional repair is not cost effective. It's a shame that this tv with very few hours of use will simply be thrown away in today's disposable society.
Hi @garisit ,
the TVs are consumer items, the design of PCBAs has been created with a focus to 2 years warranty, so they usually use the capacitor, without regardless to "long time using". If you will put your TV to the "non-authorized service", the repairman will start by exchanging all capacitors. (no the tantalus capacitors), this is "troubleshooting guide" for repair centres from the suppliers, 1 - Remove dust, 2 - Check the corrosion, if it's existing, exchange PCBA, 3 - Place a new capacitor with the same specs. 4 - Exchange PCBA - PCBA repair is not advantageous.
Maybe, if you will buy a new TV, let this TV in your house, search something about soldering, buy a soldering kit and try to exchange capacitors, for fun, in every electronics components shop, the capacitors cost about 0,5€ /pcs, so it's cheap. Then, to be sure, measure the connectivity between capacitors and PCBA. Nothing more can be measured on the capacitors. :)
