Question about Sharp 55R-WP4H 55" Rear Projection Television

Turns off after a while & will turn back again after cooling

Our Sharp 55r-wp4h (made April 2002) just past extended warranty started turning off after a while (40mins if left off for few days to 10 mins if left off for only an hour). When it turns off first video shrinks and disappears and sound goes off. The view timer led comes on with flashing off twice continuously. TV will not turn off by remote or front panel switch and will have to be unplugged. Did get an estimate for flyback for $425+tax and did not believe it is flyback. I have some basic debugging skills. On this TV cracked solder on convergance board had caused problems and was fixed. With newer TVs available for around $800 I am trying to see if I can fix this myself. Hardrocko & others thanks for your help here.

Last night after posting this problem, I pulled TV out of entertainment center and opened back cover. Turned TV on & watched flyback & circuit to see what might happen. No arcing. TV did not turn off for 45min. We watched a DVD for nearly 3 hours without TV shutting off. I fear if I close back cover, whatever is getting affected by heat will start failing again. This TV has 9 or 10 PCBs. Do you think it could be bad solder in an area I have not checked? Thanks.

After working 2 days without turning off, it started to turn off in less than 10 minutes and would not turn on.

I spent couple of hours looking at various components and testing them. Nothing I could find as bad. Then found a cracked solder at the bottom of flyback. Fixed it and set is working. I am keeping my fingers crossed.

If the problem is intermittent like I had check solder especially around components that get hot.

3d wavy look...colors are red and green, how do you adjust convergence..on model # 55R-WP4H

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

I have rear projection tv sharp 55u-wp7h. Unable to turn on tv due to view timer automatic turn on. what cause that and how to fix the problem?

I'm having same issue with same TV. It powers off after about an hour and red power light starts flashing. Only way to power back on is by unplugging TV and waiting a while, then plugging it back in, but then the TV will turn off again after a few more minutes, red light flashing again. I've checked the sleep timer and it is turned off, so any other solutions to this problem? All capacitors on power board look fine (not blown). I've read it could be solder joints in power board need to be resoldered.

Sharp 55R WP4H

I called SHARP electronics and didn't stopp calling until I got the head of cstomer relations. After about 18 months I finally got them to replace the digital board assembly with no cost to me. They agreed this was a defective part and at first offered to pay half ($537 - my half). again, I was persistence with this being a defective part. Key here is don't give up! Sharp needs to stand behind their product, period. I don't care if I am out of warranty.
Here is the phone number I have for Customer Relations
630-378-3370
Hope this helps.
Good Luck!

Gets stuck on Convergence menu

i think i know what you mean. if its the screen where you try to adjust the blue and red crosses, then you should press the "av mode" button, that takes you back to the menu, but i still don't see the adjustments I thought I was making, but I didn't have to turn it off. PEACE.
