Question about RCA L32WD12 32 in. LCD HDTV

1 Answer

Wont power up to green

I used my TV last week for about 4 hours, left for about 8 hours, came back to use it again, and the unit would turn on, but wouldn't power up to the green "on" status, and would turn back to stand by after a minute or so. I tried to let it discharge for well over 12 hours and still nothing. Any ideas?

Hello Big Bristow, It sounds like you may have a shutdown problem. This will require troubleshooting of the television. I must ask if you have experience in electronics, I ask because this is what you will need to troubleshoot this problem: a schematic of the television (to know the correct voltages, signals and signal levels) a multimeter to measure continuity of fuses, and the voltage level to match with the schematic values. an oscilloscope to measure the signals and signal levels and compare them to the schematic values a high voltage probe to measure the high voltage points on the set. These are the basic pieces of equipment needed, in the more advanced are you will need a NTSC signal generator (the Sencore VA62A Universal Video Analyzer does a good job). If you dod not have a background in electronics I would not advise you doing any work on this set and you should take it to a TV repair shop.

    Hello poster of Nov 5 2007,

    There is no quick fix for you, your set has a problem that is activating the shut down circuit. You will need a schematic, a multimeter, and at least a high voltage probe.

    1) take the back off of the set and connect the power cord to the wall power on the set,

    2) Using the schematic locate the power supply section and measure the voltages at the assigned test points note any adnormalities.

    3) Then power down the set and look at the schematic and locate each of the sections and how they connect to the power supply. alternatly power up the set and start removing each of the section and restoring them until the Main Power Supply can activate and remain activated.( This will let you know which system is causing the problem )

    4a) Once you find the system (section) at fault power down the set and use your multimeter set to ohms to measure the componentes on the board to determine if they are functioning or not (this is where the knowledge of elctronic devices comes into play)

    4b) Take the board out and contact PTS and send them the board (PTS will repair the board for you)

    5) If you decide to fix the board yourself or have PTS do it, it is your choice.

    I hope this helps

    Thank you,

Tv does not turn on

If green light flashes more than 8 times, it could be as simple as repairing or replacing the power supply. Unplug the TV ,remove the back. Look for bulged or leaking capacitors on the power supply. Do it yourselfer? only if you have soldering skills, or purchase replacement board. remember, used boards are just as old as your failed board, buy new or rebuilt, Good Luck

TV picture and sound goes off--leaving a blinking green light showing as on (power). Several times in the last week I have shut the power strip off and then on again and the TV went back on with the solid...

If TV goes off and the led stays blinking, that is because the TV is going on protection.
Protection is a special diagnostic mode that starts when an internal fault has been detected.
If this happens erratically while you are watching TV, then parts that can commonly cause the problem are PSU board, main board or digital board, ballast board and converge board on DLP, inverter on LCD, low buffer and sustain boards on plasma.

Mitsubishi WS-65513 Flashing green light

Good Day, charliek1;
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.

Mitsubishi Projection TV model WS-65513

Good Day;
The continues blinking 99.9 % of the time is four caps on your DM board. The caps are C9B01,C9B02,C9B10 and C9B11 they use 1000UHF the upgrade caps are 680 UHF- 35V. The board is on the very left hand side (from back).
I have performed this repair at least 50 times and it takes me still about 1.5 hours. If you are not handy and do not have a solder station, I would recommend that you call a factory authorized service dealer to perform this repair. With service call and ect. it will cost you around $550.00 and the repair can be done in the home, of course prices varies across the country.
Good Luck, Day, Big Irish.

Sony FD Trinitron WEGA KV-36HS500 blinking red light 6 times

My Sony KV36HS500 Trinitron is doing the same thing. Last night the next street over was hit by lightning. The "7" blink pattern was happening, so like the manual stated, unplug it for 4 hours. Which I did. The t.v. is back up and running fine. It's a nice t.v., better than the plasma I paid over a grand for, that's already shot. It's a good t.v. and good that Sony put in the stand by protection to prevent the t.v. from dying an unnecessary young death. Patience, don't rush it, unplug the t.v. and leave it sit. Also, don't use a power strip, that was my mistake, and unplug your t.v. if storms are in the area, I was too lazy to and now I had to deal with this, in 8 years, only twice did this happen. I'd buy another one tomorrow if they still made them.

Won't turn on. Constant blinking green light!

There are 4 1000uf capacitors on the DM board that prevent your set from completeing the boot sequence. replace these with the Radio Shack eqivalents and your problem should be resolved. The 4 capacitors are located right next to each other in a group. Hope this helps.
