Re: tv will not turn on
Look on Deflection board 3 capacitors need replacing cp150---cp114----cp120 one is 2200uf 16v Two of them are 220uf 35v. Buy capacitors at Radio SHack. If cp150 is puffed up on top it is bad so replace other 2 caps as well.

What is the source of the TV signal? I know many monitors have a "power-saving mode" that returns the unit to standby if there is no signal coming in.
Check that the signal cables are working (try swapping cables). Make sure the source is on before turning on the TV. Press the Input button to select a different source. Make sure that the source signal is not refreshing (or synching) at a rate that is incompatible with the TV. (If your source is a PC that was previously connected to a CRT monitor, the refresh rate should be reset to 60 Hz before connecting the computer the the Pioneer 424MV.)
I hope this helps.
Cindy Wells (Pioneer TVs usually give a blink code if there is a hardware problem that prevents it from turning on.)
After the TV has shut down, without pressing reset: press and hold both the Device (Input) and Menu buttons on the front panel until the green light starts flashing. It will flash a two digit code: 3-4, 3-8, 5-7, etc. You may have to let the TV shut down a couple of times (without pressing reset) before it will give the code.
Please post the code to help me determine the section of the TV that has failed and what it will take to repair it. It may be a good idea to repeat the test a few times to make sure the TV is giving the correct code.
if the light just constantly blicks green and doesnt stop. You will need the" V26 DM repair kit " which will usually repair that issue. You can get the repair kit at the following link which includes the replacement capacitor and instructions http://servicemanuals.vstore.ca/
Your chassis V21, 2002 model TV has a problem, but to determine what, try this; press the 'input' and 'menu' buttons on the TV"s front panel for at least 10 seconds. Count the blinks (after releasing); eg blink, blink pause 6 blinks = code 26. The code will repeat 3 x's. The most common problem is the convergence IC's are bad or fluid on the boards.
