Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

Did u check the pico fuse and all those resistors on the tv convergence board to make sure with ones are good resistors which are not good resistors and replace all them resistors too?U didn't do that should get it tested and replaces all those dying resitors.Try website like Tvrepairworld.com look up ur Hitachi tv model what resistors and pico fuse u require to check.

Hitachi 43UWX10B 43" Power Light flashes Continuously


I doubt if its the fuse. We just helped a customer with a very similiar problem. Its more likely that the convergence IC have failed and shorted out. When this happens one of the symproms is that the TV will shut down and chirp. Goto www.TvRepairKits.com and click the contact us button. They can provide you with more instructions on how to test if this is the problem.

Hitachi 53UWX10BA HDTV with convergence problem for blue


No there are no quick fix options for this fault. The convergence amplifiers operate similar to a high power audio amplifier, so if there is an impairment anywhere in the system, it will result in distorted audio, or in the case of television convergence amplifiers, a color won't align. The convergence power pacs need to be replaced and the out of tolerance precision resistors located near the power pacs need to be carefully checked and replaced as necessary.

It is also possible that there are root faults that cause the amplifiers to go bad which include bad connections or a bad digital control module. This repair is possible for anyone having basic electronics knowledge and soldering skills.

DP23 LED not lit on deflection board no picture on tv


Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.
