from the model number you have a 42" set,,the v_set and v_scan voltages need to be set 15vdc lower..this should take care of it,,if not then the plasma panel is bad

SOURCE: v-scan voltage adjustment
If you adjust v-scan make sure you adjust it for the setting that is marked on the panel when you take the back off. Why do you want to adjust v-scan? are you noticing red pixels firing or green ones? This is a diffusion problem and i am familiar with the fix for that. Let me know and we can go from there. Also what is the version of the HP-R5052? Talk to you soon . Thank you Jay

To reset the remote so that it works properly again, take the batterys out of the remote, then press and hold the power battery for at least 30 seconds to drain out any power left in the hadnset , then replace battterys and it should work again. We had this fault and this solution worked for us

It's not the x main. 90% of the time it's a y buffer that goes out. It's usually the top buffer. 3/4 of the time the buffer takes out the y main board too. You cannot just replace the y-main or buffer because it will just burn out the other within seconds. Also about 1/4 of the time it'll take out the top transformer on the power supply too. The solution? First disconnect the power to the y main board. turn on the television and check the voltages coming off of it. Careful it's high voltage 208V! Remember it's DC too. Then disconnect the buffers from the y main board. You can try powering the y-main up to see if the little LED lights up. This does not indicate it's working though but it'll tell you if it is possible to fix. The fixes for these boards is only for electronics guys. It usually involves replacing 1-3 capacitors and 1-4 FET's. Since a bad buffer can take out a good y main in seconds it's usually recommended that one replace all 3 boards at the same time. It's a $250 fix. How do I know all this? I've now repaired 5 of these televisions. I owned one and spent close to 600 repairing it. I bought misc parts and broken sets online for months before I had 2 different repair guys walk me through the process of repairing them. I had so much cash tied up in parts that I bought 3 more dead sets and repaired them to justify all my spending. I've never had an x board fail. I've had EVERY top buffer fail. I've had all but 1 y-mains fail. and 1 lower buffer fail. I've also had the y buffer fry it's top chip, blow a capacitor and FET on the y-main, and fry the top transformer on the power supply before my eyes. It only took 5 seconds. Replacement of the 3 y boards will almost always fix the sound but no picture problem. Hope this helps!
