Question about Projection Televisions

Open Question

RCA TV Model no 52RH8LA problem - switches on when it wants to. All other functions fine when operating. When TV refuses to switch on, standby LED flashes red. To date: already replaced all electrolitic caps in power supply and checked secondary power supply caps. Suspect from discussions with other technicians, capacitor on main motherboard.

SOURCE: Main power light turns on but i have no picture or sound

Take a closer look at the power board fuses. There is a fuse numbered 106 a little ways away from the rest of them. I have this same model and got it working long enough to diagnose a bad flyback transformer by replacing this fuse with one from Radio Shack. At some times, I could put in a new fuse and have the set work for a few weeks. The flyback transformer is available from parts.pioneerelectronics.com for around $60.

SOURCE: tv won't turn on 4 blinking led

Hi,
Red led blinks 4 times is an error code that shows that fan is not running in tv, check fans connections and make sure all are plugged properly.
Thanks.

SOURCE: Mitsubishi WD-62525 Red Status Light After Cap Replacement

Mitsubishi V26 error code 41 with solid red status indicator is caused by leakage from capacitors C9A37 and C9A38 (3300mf/16v). The result is a bad fuse F9A02 (15amp pico) which reports error code 41 indicating short protect. The Mits part number is 283P144040 but any PICO 15a fuse will work.

My RCA model no. SLD55A55RQ when i turn it on it flashes white,blue,red,green how do i stop this or fix this?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

An Rca tv turns on then immediately turns off. Rca tv model number 20F512T. It has picture, audio, and no blinking lights. I've checked the main board and no problem what so ever. Nothing burned or loose....


If it turns off going standby, and led is on, then it is on protect, and remaining parts must be tested.

If it turns off completely, and you can restart it with the On button, then the board with controls is faulty.
If it does switch off completely (no light), and only comes back on after unplugging power cord for a while, then there is a different internal fault that is not starting protection circuit , but causing shutdown.
After double checking the PSU board, you will have to test a couple of ICs on main controller board, the deflection circuit and flyback transformer. Check also for broken solder joints and thaces of shorts on all boards and components (eg. burnt areas, blown capacitors), as a short can potentially cause sudden shut down.

Here schematics.

Here all parts for your TV.
