The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hi.

Since the problem is intermittent, start checking from the lamp cage door lock. A defective lamp cage lock can result in similar problems.

The same problem is commonly given by a defective lamp. There is no way of testing a DLP lamp, then the lamp gets usually replaced before repairing the rest. If the lamp has many hours of use, replace the lamp first, then work on the rest.

If the lamp is OK, then it is either a bad PSU or a defective ballast. The PSU supplies power in different voltages. Each line is independently used for a different function. If the PSU is defective there can be intermittent power to the lamp while the rest of the TV functions are working. Power to the lamp goes through the ballast. The ballast is the board that supplies power to the lamp. With both PSU and Ballast problem you may have video going off, or TV going to forced standby with LED blinking with no additional problem (no sound or picture issues before going off).

Ballast and PSU are tested reading voltages. If both parts test OK, then the problem is the digital controller board. In that case the protection circuit it is likely faulty.

Here a service manual for this model at $7.99: M50WH185 ...

what caused the inital problem was a surge of energy caused by the storm. the exact problem, i don't know but it may just be that some of the power cord(including the power cord wires on the of the TV) wires have blown

your power supply unit is going bad you dont have much longer before it goes your volume buttons picture light. screen all run through it. go to vancebaldwinelectronics.com to replace it.

well if they gave you a quote for it then feel lucky most rca parts are hard to get if possible at all i worked at a leasing outfit for some time and our rca products were unrepairable due to this problem really just get a good budget brand like toshiba or lg and check for good reviews before buying ok :)

Hi,

It is not required to set the Picture after replacing the Lamp and Housing. To change the Picture Settings press the MENU button on the Remote, highlight PICTURE and press OK. There you'll get the option to select Picture Preset Mode, Picture Settings, Screen Format, Advanced Picture and Screen Adjust mode. You can customize the settings by selecting the each Picture Menu options.
Click here to download the manual of the TV. View page # 39 for the instructions to change the Picture Menu.

Good Luck!

You need a new projector bulb. Google up your model and buy the best warranteed one you cAN FIND. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!

your lamp for the M502h185 is the following

RCA 270414

that part is available several places on the interent and you can buy the bulb itself or the bulb mounted in a new housing (if yours is damaged) ... if your housing is ok and you can figure out how to mount the new lamp in it then its a little less to get only the bulb ..
here is one place that has both options:

Sounds like a worn lamp. You should pull it out and have a look at it. If you want some more information on projection lamps and what to look for when inspecting them, see my Tips & Tricks. I made a tutorial on them. I hope this was of some assistance.

There are quite a few possibilities with the 5 blinking lights:

• Possibly a bad power supply board (check the lamp first, then troubleshoot further)
• The lamp is faulty
• The ballast is weak and unable to ignite the lamp
• The ballast is faulty
• The color wheel is not responding
• The light engine is not responding
• The lamp is not seated properly, or has not made a connection with the ballast.

Are there any other indications?

your flyback on your deflection board is the problem, rca has a notorious problem with these, some will kill the audio also,just replace the whole deflection board

I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson

Try to check the power supply output side where anything could came into contact with positive and negative line for which when you press play button then it shuts down.

RCA video cables handle analog signals. HDMI cables carry digital video signals. You need a converter. If you are using a component video converter, check if you swapped two of the three RCA video cables. (There are some A/V projectors that can do the translation of RCA and HDMI internally. Most TVs do not.) I hope this helps. Cindy Wells (One of my family's TVs used a dongle to condense the analog video signal to a single port, swapping blue and green gave a black and white output, IIRC.)

Most modern tv remotes are not normally designed to be repaired. You will possibly need to replace it. there are plenty of cheaper after market version that will do the job just as well. Your other option, and yes I know this is a silly answer, when you want to mute the TV is to simply press the volume down button to zero then turn it back up when you want sound.

you will need to rind RCA to whatever input is on your tv google RCA to HDMI copy and paste link for manual https://www.manualslib.com/manual/313476/Rca-Vr677hf.html#manual

You need the TV codes not the remote ones. I would use the Remotes code search feature as the Sanyo has allot of codes and you may spend hours going through them. Sanyo remote codes 0154 0208 0157 0280 0484 0292 0721 0011 0036 0045 0370 0068 0339 0072 0216 0104 0217 0145 0146 0156 0555 0381 0412 0009 0508 0544 0163 0799 0037 1154 0108 0159 0556 0486

The fuse on an RCA flat screen TV is typically located on the power supply board near one of its corners. The power supply board is the board with an array of capacitors, resistors, and heat sinks on it . The fuse is a small cylindrical tube with metal caps and is relatively small compared to other components on the board . If you have never seen a circuit board before, finding the fuse may be tricky. You can consult the user manual for your TV if you need help locating the fuse . TV Fuse Replacement Guide: Locating and Replacing Your TV Fuse - PointerClicker.com Replacing the fuse should be done with caution, especially if it is soldered to the board, as errors could lead to costly damage. You can check if the fuse is blown visually or with a multimeter-like tool. If you are unsure about how to replace the fuse, it is best to seek professional help.
